2.1 Error diagnostic messages F...

Many areas are monitored in connection with operating modes and parameter settings. An error message is generated if a condition is discovered which no longer allows proper operation.

Error Classes

The errors are separated into four different error classes. The error class is evident from the diagnostic message. They are determined with the drive's error response.

Error class : DiagnosticMessage: Drive Reaction:

Fatal F8xx Torque free switching

Travel range F6xx Velocity command value-zero switch

Interface F4xx In accordance with best possible deceleration

Non-fatal F2xx In accordance with best possible deceleration

Fig. 2-1: Error Classes and Drive Reaction

Drive's Error Reaction

If an error state is detected in the drive then an automatic operation of the drive's error response will be started as long the drive is in control. The H1 display blinks a Fx / xx. The drive's reaction can be parameterized by P-0-0119, Deceleration as best as possible, with interface and non-fatal errors. At the end of each error reaction the drive is switched off.

Reset the Error

Errors will not be automatically deleted but must be:

· Reset from the control through the initialization of the command S-0-0099, Reset Class 1 Diagnostics, or

· reset by pressing the "S1" button.

If the error state is still present then the error will be immediately detected again. A positive edge bit on the control enable signal is necessary in order to turn on the drive again.

F207 Switching to uninitialized Operation Mode

Cause:
0 has been selected in at least one of the four mode parameters S-0-0032..35. This mode was selected by the bits 8 and 9 in the master control word when the drive controller was on.

Remedy:

F208 UL The motor type has changed.

Description:

The settings for current regulation, velocity command, and position loop are stored in the feedback of the motor. After powering up, the drive compares the motor type stored in the parameters with the connected motor type. If the two do not match, the drive remains in this state. By pressing the S1 key, the drive overwrites its stored parameters with the control loop parameters from the motor feedback.

Cause:
The motor has been exchanged. A parameter file has been loaded, but the parameter P-0-4036, Contacted motor type contained a different motor type.

Remedy:
Command C700 Basic Load or press the S1 button.

F209 PL Load parameter default values

Description:
After the firmware is replaced (EPROMs), if the parameters have been changed in regards to the old product, the drive displays "PL". By pressing the S1 button on the drive or by starting the command "load basic parameters", all the parameters will be erased and restored with the default values.

Cause:
Product was replaced. The number of parameters in comparison to the new products has changed.

Remedy:
Press S1 button on the drive controller and all the paramters will be erased and restored with default values

WARNING -> This overwrites all parameters and positioning blocks.

F218 Amplifier Overtemp. shutdown

Description:
The temperature of the DKC heatsink will be monitored. If the temperature of the heatsink is too high, the drive will power down in order to protect against damage.

Cause:
1. Ambient temperature is too high. The specified operational data is valid up to an ambient temperature of 45°C.

2. The DKC's heatsink is dirty.

3. Air flow is prevented by other assembly parts or a control cabinet panel assembly.

4. Heatsink blower may be defective

Remedy:

For 2. Remove any obstruction or dirt from the heatsink.

For 3. Install the device vertically and clear a large enough area for proper heatsink ventilation.

For 4. Exchange drive.

F219 Motor Overtemp. shutdown

If the motor temperature exceeds the value in S-0-0204, Motor shutdown temperature, the drive will generate this error message. The value in S-0-0204 is fixed at 150°C for MHD-,MKD- and MKE motors. The appropriate value must be entered from the motor's technical specifications for all other types of motors. For motors of series: 2AD, 1MB, LAF, LAR, and MBW, the current motor temperature can be called up with parameter S-0-0383, Motor temperature.

Cause:
1. The motor became overloaded. The effective torque demand on the motor was above its permissible continuous torque level for too long.

2. Short circuit or ground in the connection to motor temperature monitoring.

3. Instability in the velocity control loop.

Remedy:
For 1. Check the layout of the motor. For motors which have been in operation for longer periods of time, check to see if the operating conditions have changed (in regards to cleanliness, friction, moved components, etc.).

For 2. Check the wiring to the motor temperature monitor X6/1 and X6/2 for grounds and short circuits.

For 3. Check the velocity control loop parameters (see the functional description).

F221 Error Motor temp. surveillance defective

Cause:
Short-circuit in the wiring to the motor temperature monitoring.

Remedy:
Check the wiring to the motor temperature monitoring X6/1 and X6/2 for short-circuits.

F226 Undervoltage in power section

The DC bus voltage is monitored in the power supply module. The drive controller is notified via the control voltage bus whether the DC bus voltage is above a minimum permissible value. If the CD bus voltage falls below that threshold, the DC bus voltage message will be removed by the power supply unit and the selected P-0-0119, Best possible deceleration will be performed. Requirement: The P-0-0118, Power off on error parameter has been set such that the undervoltage condition is handled as a fault.

Cause:
1. The power is switched off without having de-activated the drive via the controller enabling signal (RF) before.

2. The drive has been activated via the controller enabling signal (RF) without having activated the power section before.

3. Malfunction of the power supply unit.

Remedy:
Ref. 1.+2. Checking the logic that is used for activating the drive in the connected controller.

Ref. 3. Eliminate the malfunction of the power supply unit. See Applications Manual of the power supply unit.

F228 Excessive Deviation

When the position loop is closed, the drive monitors whether it is able to follow the specified command value. This is done by calculating a model position value in the drive and comparing that value with the actual feedback value. This error is generated if the difference between theoretical and actual position value permanently exceeds the value of the S-0-0159, Monitoring window parameter.

Cause:
1. The drive's acceleration capacity is exceeded.

2. The axis is blocked.

3. Incorrect parameter values set in the drive parameters.

4. Incorrect parameter values in S-0-0159, Monitoring window

5. The power supply has been switched of while the controller enabling signal is applied. Possible cause: Malfunction in an AC servo drive at the common power supply module.

Remedy:
Ref. 1. Check the S-0-0092, Bipolar torque/force limit value parameter and set it to the maximum permissible value of the application. Reduce the specified acceleration value from the controller (see controller Manual).

Ref. 2. Check the mechanical system and eliminate jamming of the axis.

Ref. 3. Check the drive parameters.

Ref. 4. Set the parameter values of S-0-0159, Monitoring window.

Ref. 5. Check AC servo drive with error message different than "28".

F229 Motor Encoder Failure: Quadrant Error

Cause:
1. Defective encoder cable.

2. Disruptive electro-magnetic interference on the encoder cable.

3. Defective motor encoder interface.

4. Defective drive controller.

Remedy:
For 1. Exchange the encoder cable.

For 2. Keep the encoder cable well away from the power cables.

For 3. Exchange the motor encoder interface.

For 4. Exchange the drive controller.

F233 External Power Supply Error

Cause:

The DEA plug-in modules have isolated inputs and outputs. Proper operation of those inputs and outputs requires an external 24-V voltage to be applied. The drive monitors that voltage as soon as a DEA plug-in module has been installed.

Remedy:
Check the external 24-V power supply.

Name: Unit: min.: typ.: max.:

External operating voltage +UL V 18 24 32

External current consumption IL mA 100

Fig. 2-5: External power supply

F236 Excessive Position Feedback Difference

Cause:
In the communication phase 4 transition check command, position feedback value 1 and position feedback value 2 are set to the same value and the cyclic evaluation of both encoders is started. In cyclic operation (phase 4), the position feedback difference of both encoders is compared with S-0-0391, Monitoring window ext. feedback. If the amount of the difference exceeds the monitoring window, error F236 Excessive position feedback difference is diagnosed, the parameter-selected error response performed, and the reference bits of both encoders are cleared.

1. Incorrect parameter for the external encoder (S-0-0115, Position feedback 2 type parameter, S-0-0117, Resolution of external feedback).

2. Incorrect parameter setting of mechanical system between motor shaft and external encoder. (S-0-0121, Input revolutions of load gear; S-0-0122, Output revolutions of load gear S-0-0123, Feed constant).

3. The mechanical system between motor shaft and external encoder is not rigid (e.g. gear play).

4. Defective encoder cable.

5. Defective module (DLF or DEF) for the evaluation of the external measuring system.

6. Maximum input frequency of the encoder interface exceeded.

7. External encoder is not mounted to the driven axis.

8. Incorrect reference dimension of an absolute encoder.

Remedy:
Ref. 1. Check S-0-0115, Position feedback 2 type parameter and S-0-0117, Resolution of external feedback

Ref. 2. Check S-0-0121, S-0-0122, Input/Output revolutions of load gear and S-0-0123, Feed constant

Ref. 3. Increase S-0-0391, Monitoring window ext. feedback.

Ref. 4. Replace encoder cable.

Ref. 5. Replace module for the evaluation of the external measuring system.

Ref. 6. Reduce the velocity.

Ref. 7. Set S-0-0391, Monitoring window ext. feedback to 0 (de-activate monitoring function)

Ref. 8. Perform P-0-0012, C300 Command 'Set absolute measurement'.

F237 Excessive Position Command Difference

Cause:
When the drive is operating in position control, position command values which come via the SERCOS interface are monitored. If th velocity equired of the drive by two successive position command values is reater than or equal to the value in S-0-0091, Bipolar velocity limit alue, position command value monitoring is initiated. The Excessive position command value is stored in parameter P-0-0010. The last valid position command value is stored in parameter P-0-0011. If position data are to be processed in modulo format, then the interpreation of the command values is also dependent on the value set in S-0-0393, Command value mode for modulo format. The parameter should be set for the "shortest path" (0).

Remedy:
Compare S-0-0091, Bipolar velocity limit value with the velocity in the program and adjust to match it, if necessary.

F242 External Encoder Failure: Signal too small

Cause:
The analog signals of an external measurement system are used for high resolution analysis of that measurement system. These are monitored according to two criteria:

1. The pointer length, which is calculated from the sine and cosine signals, must be at least 1 V.

2. The maximum pointer length resulting from the sine and cosine signals must not exceed 11.8 V.

Remedy:
1. Check the measurement system cable.

2. Check the measurement system.

F245 External Encoder Failure: Quadrant Error

A hardware error was discovered in the high resolution position interface for "DLF" sine signals of the external measurement system.

Cause:
1. Defective encoder cable.

2. Disruptive electro-magnetic interference on the encoder cable.

3. Defective DLF module.

Remedy:

For 1. Exchange the encoder cable.

For 2. Keep the encoder cable well away from the power cables.

For 3. Exchange the DLF module.

F248 Low Battery Voltage

Cause:
For motors of series MKD and MKE, the absolute position information is stored by a battery-powered buffer in the motor feedback. Th battery is designed for a 10-year life span. If the battery voltage falls below 2.8 V, this message appears. The absolute encoder function will still be preserved for about 2 weeks.
