Wiring: Power to Mitsubishi RESET pin when E-Stop

About

This wiring scheme may not exist on older SMT benders. The wiring allows for power to run to the RESET pin on the Mitsubishi drive whenever the Master Power and Safety Relay Contactors are deenergized. This clears the Mitsubishi drives of any faults, and decreases the number of times the drives will stay in a faulted condition even after pulling the E-Stop.

STEP 1: Wire Jump

Wire jump point 22 in M-1 to point 22 in M-2

STEP 2: Attach a Power Line

Tap into power by finding wires 2432 at the terminal strip. Run a wire from the strip up to an into point 21 of the M-1 contactor

STEP 3: Run the Mitsubishi RESET Wire To M-2

• Run wire from point 14 in the B cable on the Mitsubishi drives to point 21 of the M-2 connector.
• There is a cable running from both the Feed and Rotate drives. Point 14 from both cables must be found and used to connect to the M-2 contactor.
• If the cable is a stock Mitsubishi cable, then there will be many wires in the cable. Wire 14 will be white with a green stripe
• If there is no wire 14, then you will need to run a small wire (24 AWG) into the connector at the drives. The connectors use solder cups. Solder the wire into point 14 at the B connector.
