About
On some older benders, the Mitsubishi drives power down when E-Stop is pressed. This approach causes the Feed and Rotate axes to loose the HOME status in the I2T modules when the E-Stop is pressed.
So with newer CNC Bender software, it is necessary to keep the Mitsubishi drivers powered - even when the E-Stop is activated.
STEP 1: Check the State of the Drives at E-Stop
|
Set MASTER POWER ON, Press the E-Stop, then examine the drives LED screens. If they are blank, then the drives are off, and you will need to perform this wiring change during a CNC Bender upgrade.

STEP 2: Find Three Wires
Find the three wires entering the top left side of the white fuse buse to the left of the Feed drives.
- The wires will be labelled 3L1, 3L2, and 3L3.
- Trace those wires to the M-2 contactor.
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 CN1B 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 CN1B connector.
