I use MC Power, and MC_MoveVelocity to define speed of frequency inverter. How I can completely reset velocity to 0 (zero), 3L+ line (supply for outputs) is break. How to control turning of or on Q0.1 for direction? Thanks.

If is that parameter 0 direction output depends of sign of Velocity parameter. If direction parameter 1 output is ON (OFF), if 2 output is OFF (ON). One thing that iI noticed is that you can not change direction or any other parameter if axis disabled (MC_Power Enable input is false). Best regards.
