I am building a tool where I need to change the direction of the 90 VDC gear reduction motor with two foot switches.

Power is coming from a motor controller with variable speed. Terminal 4 and 5 have 90 VDC across them.

Motor has green, white and black wire, black and white to terminal 4 and 5 drive the motor fine, reverse the terminal and the motor runs in reverse direction.

I have 2 foot switches that have NO, NC, COM terminals on them.

Is there a simple way I can wire this motor to not run when neither switch is pressed, and run in either direction based on which switch you push?

Sorry for the non-technical description, I'm not a electrical guy, but a mechanical guy.

    \$\begingroup\$ Do you have a manual for the motor controller? Is it a standard (eg. KB) type? \$\endgroup\$ – Spehro Pefhany Mar 24 at 1:33

    \$\begingroup\$ As a mechanical guy, do you think your geared motor system will be just fine if you suddenly reverse its direction from full-speed forward to full-speed backward? \$\endgroup\$ – jonk Mar 24 at 1:57
