We have a 600w 220vDC motor that we need to control from the breakout board. Is there a suitable motor controller available with a PWM or 0-10v input and an inhibitor switch? Everything I've seen doesn't have an inhibitor switch and it looks like the only way to turn the motor controller off and on via the breakout board is through a relay on the 240vAC supply. I tried a solid state relay on the DC output to the motor, although there are separate issues with solid state relays and it wasn't satisfactory.

We do have a great deal of experience with VFDs and AC setups already yet I'm not really willing to junk the DC motor, as it's fine for the job, and an AC setup would be another £250 expense that isn't really necessary. Information on DC setups seems to be a little thin on the net. How have other people addressed this issue?
