How can I set the home velocity HV for DMC-21x3 controller?

Hello mshaheen61,
HV command is not available for a DMC-21x3 controller.

An alternative would be to use FE and FI commands instead of HM command. HM command consists of two stages for steppers and three stages for servos. You can use FE command to find home input transitions and FI command to find the index as described for the third stage of HM command for servo motors.

For more information please see the command reference for HM, FE, and FI commands.

Thank you,
