Drive stays in AF although enable request is false

Any comments on drive staying with torque after input to MC_Power from CXA_PLCOPEN library is written to false? It happens when a motion error is generated while drive is with torque. When the error is still present the toggling of enable input to MC_Power does not have an effect.

You would get a system report from the core, but nothing happens when I press the button to create it.

Drive: XCS2-W0023ARN-02AETM5NNNN-S0312N2NNNN3NN

Firmware: FWA-XD1-AXS-V-0312N-NN.00

Motion app: 1.14.0

Hello,

could you please check if the MC_Reset solves your expects?

As my colleague said you have to follow the state machine of the axis. At the moment it is not possible to disable the drive as long as an error is present. On the other hand the drive should automatically be disabled as soon as an error is present.

Hello,

Please check that the call to the MC_Power is not inside an IF/ELSE statement.

Otherwhise if you change the enable input but you don't call the function block , it will not make any effect and the drive will stay in AF.
