What to do if the Festo CMMB-AS-0x shows an Overcurrent error?
If the Festo Controller displays an overcurrent error, it means the instantaneous current exceeds the overcurrent protection value. First, check the motor cable for short circuits. If the problem persists, replace the controller.
What to do if the Festo CMMB-AS-0x displays an Overvoltage error?
If the Festo Controller displays an overvoltage error, it means the supply power voltage exceeds the allowable input voltage range, or in case of emergency stop, there is no external braking resistor or braking. Check to see if the supply power voltage is unstable and if a suitable braking resistor is connected.
What should I do if my Festo CMMB-AS-0x Controller shows a 'Wrong motor model' error?
If your Festo Controller shows a 'Wrong motor model' error, it means the current motor type is different from the motor type saved in the controller. You can either access EA01 via the KEY to confirm the motor type and then access EA00 and set it to 2, or access EASY_MT_TYPE (0x304101) via PC software, confirm the value, and then save the parameter.
Why is my Festo CMMB-AS-0x showing an Encoder not connected error?
If your Festo Controller shows 'Encoder not connected' error, the encoder wiring is incorrect or disconnected. Use a multimeter to check the connection of the encoder signal cable.
What to do if the Festo CMMB-AS-0x displays an Undervoltage error?
If the Festo Controller displays an undervoltage error, it means the power voltage input is lower than the low voltage protection alarm value. Check to see if the supply power voltage is unstable.
What to do if the Festo CMMB-AS-0x Controller shows an Encoder internal error?
If the Festo Controller displays an 'Encoder internal' error, it indicates an internal encoder error or that the encoder is damaged. First, access panel address d3.51 Encoder_OP by KEY and set it to 1. Then, try to reset the controller error. If the error persists, replace the motor.
What to do if the Festo CMMB-AS-0x Controller displays a Chop Resistor error?
If the Festo Controller displays a 'Chop Resistor' error, it indicates that the braking resistor is overloaded or its parameters are not set correctly. Set the resistance and power of the external braking resistor through d5.04 and d5.05.
What should I do if my Festo CMMB-AS-0x shows a 'Motor or controller IIt' error?
If your Festo Controller shows a 'Motor or controller IIt' error, it means the brake is not released when the motor shaft is rotating. Measure the brake terminal voltage to ensure it is correct and that the brake is released when the controller is enabled. Eliminate any mechanical sticking by adding lubrication and reduce the acceleration or load inertia.
How to resolve a 'Closed loop direction' error on a Festo Controller?
If you encounter a 'Closed loop direction' error on your Festo Controller, which indicates a different direction between the motor and position encoder, change the encoder counting direction.
What does 'Low Logic Voltage' mean on a Festo CMMB-AS-0x and how to fix it?
If the Festo Controller indicates 'Low Logic Voltage', it means the logic power voltage is too low. Check to see if the logic power voltage is unstable.
