System Failure

When the CLM detects an error, all outputs are turned off and the error message appears on the CLM display module. Typically, the word "ERROR" appears on the top line of the display. The second line displays an error message. After the error condition has been corrected, the message must be cleared by pressing the CL key on the CLM keypad, or by providing a +24-volt input to the external Clear input (connector X3, pin 8).

8.1 SYSTEM RELATED ERROR CODES

1.The parameter containing the invalid input can be displayed by switching into Parameter mode and pressing the CL key on the CLM keypad, or by providing +24 Vdc to the external Clear input (connector X3, pin 8).

2.Consult chapter 4 for the minimum and maximum limits of the parameter in which the error occurred.

1.The Emergency Stop pushbutton has been pressed.

2.The Emergency Stop circuit has been broken. Consult the machine builder's wiring diagrams to determine what could have caused the break in the E-Stop circuit.

3.+24 Vdc has been applied to CLM connector X5, pins 1 and 2, but CLM connector X3 is not installed.

4.+24 Vdc must be applied to CLM connector X3, pins 36 and 37. Also, the reference (0 Vdc) must be applied to the CLM connector X3, pins 34 and 35.

1.If this error occurs every time the CLM is turned off and on, replace the back-up battery. This error might also occur if the firmware is removed or a different CLM firmware is installed.

2.Verify that every CLM-LA parameter has valid numbers stored in each parameter. The CLM-LA parameters might contain asterisks (*), indicating invalid data has been entered. Refer to chapter 4 for information on how to enter the CLM-LA parameters.

1.If this error occurs every time the CLM is turned off and on, replace the back-up battery. This error might also occur if the firmware is removed or a different CLM firmware is installed.

2.Verify that every CLM-LA program ha  valid numbers stored in each progra  block. The CLM-LA program commands might contains asterisks (*)  Refer to chapter 5 for information on ho  to enter the CLM-LA program commands.

3.This error will also occur if the number of decimal places in parameter B007 has been changed, but the program blocks were not re-stored correctly. Re-store the program blocks by downloading a program from Motion Manager or by scrolling to the edit screen and pressing the Block Store key.

1. Verify that Parameter mode is selected before transmitting parameter information to the CLM.

2. Check CLM display screen for status of system inputs.

1.The program comman  contains asterisks (*). Refer to chapter 5 to determine if the program command is used properly.

2.The auxiliary input or output programmed in the CLM program is zero.

1.The BCD program commands is programmed incorrectly.

2.Verify auxiliary inputs 1 through 8 are in a BCD format.

1. The BCB, BCD, and BMB program commands can result in a jump or branch to a target bloc  greater than 999. This jump is caused by combination of an offset, jump distance, or binary input. If either of these command  are used, refer to chapter 5 to determine if the program command is used properly.

2. The branch or jump command contain  an asterisk (*) in the target block. Refer t  chapter 5 to determine if the program command is used properly.

1. The Direction Axis parameter must be compatible with the wiring of the encoder or with the command inputs E1/E2.

2. The data entered in the Encoder Data parameter does not correspond to the  encoder used on the back of the axis motor. Check that the lines per revolution  entered in the parameter matches the data on the encoder.

3. The RPM/Volts in the  Drive Sensit. parameter does not correspond to the RPM/Volts on the axis amplifier's command input (E1/E2).

4. The axis moved without a command voltage being applied to the amplifier  command input (E1/E2), i.e., the axis was physically moved by means other than the motor.

1  The axis servo amplifier does not have power applied. Verify that the Bb contact  on the axis servo amplifier are closed. For more information on conditions tha are needed to apply power, consult the manual for the servo amplifier being used.

2. Th  Encoder Data parameter does not correspond to the encoder used on the back of the axis motor. Verify that the encoder value stored in parameter corresponds to the encoder mounted on the motor.

3. The RPM/Volt in the Drive Sensit. Axis parameter does not correspond to the RPM/Volts on the axis servo amplifier command input (E1/E2).

4. The Accel. Rate parameter value is too large. The motor is unable to accelerate at this rate.

5. The axis Amplifier Enable output is not connected to the Amplifier Enable (RF) input on the amplifier.

6. The axis encoder cable is not connected to the CLM encoder connector, or the axis motor encoder cable is not connected.

7. The axis encoder cable is wired incorrectly or is defective. 

8. The axis encoder is defective.

9.The motor cannot turn because of a mechanical bind.

1. The absolute encoder valu  stored in the Encoder Data parameter does not correspond to the encoder used on the back of the axis motor. Verify that the absolute encoder value stored in parameter corresponds to the absolut encoder value.

2. The axis absolut  encoder cable is not connected to the CLM encoder connector or the axis absolute encoder cable is not connecte to the axis motor.

3. The axis absolut encoder cable is defective or wired incorrectly.

4. The axis absolute encoder is defective.

1. The absolute encoder value stored in the Encoder Data parameter does not correspond to the encoder used on the back of the axis motor. Verify that the absolute encoder value stored in parameter corresponds to the value shown on the absolute encoder.

2. The axis absolute encoder cable is defective or is wired incorrectly.

3. The axis absolute encoder is defective.

1. The commanded positio  has exceeded the axis minimum travel limit.

2. Verify that the axis minimum travel limit parameter is correct.

1. The commanded positio  has exceeded the axis maximum travel limit.

2  Verify that the axis maximum travel limit parameter is correct.

1. Verify that the axis parameters are correct. Axis can be homed in Manual or Automatic mode. Refer to chapter 4, Parameters for mor   information on axis homing.

2. Verify tha  the axis position command in the CLM user program is correct. Refer to chapter 5 for more information on the axis position commands.
