Suggested Remedy
Check the wiring of the STO circuit and any switches or devices within that
circuit. Ensure that any intermediate devices are not activating momentarily
during drive operation.
Can happen if an external 24V supply is used and the voltage ramps up slowly on
power-up. Could also happen if the drive 24V rail is overloaded and collapses
momentarily, check the loading of the 24V rail and all control connections.
Contact the supplier of the drive for further advice
A speed error has been detected (Locked Rotor)
Check the motor wiring, disconnect the drive and measure the phase to
phase resistance from the motor cable
Check the motor wiring, disconnect the drive and measure the phase to
phase resistance from the motor cable and refer to motor datasheet
Check the motor wiring
Check the motor wiring
Check the motor wiring
Check the motor wiring
Check the Modbus wiring, ensure that the 0V common is used, ensure that
the communication wiring is kept away from any power wiring
