problem with IRB 1400

[potis]

We have a problem with a usedIRB 1400. we made a cold start up but the is an error when we try to power the motors. it says

37001: Contactor activate Error
Motor On contactor did not activate or
Motor On signal is not distributed
through auxiliary contact
Check:
Restart system
Replace Motor On contactor or
auxiliary contact
Replace system board.

before the cold start up the robot was working. any ideas?? where is the motor on and the auxiliary contactor??

After the cold start, you installed the robot system, didnt you? Have you checked the panel unit card? What about the leds EN, MS, NS.....?

MOTORS ON and MOTORS OFF modes
The principle task of the safety circuit is to ensure that the robot goes into MOTORS
OFF mode as soon as any part of the chain is broken. The robot computer itself controls
the last switches (ENABLE and MOTORS ON).
In AUTO mode, you can switch the robot back on by pressing the MOTORS ON button on
the operator’s panel. If the circuit is OK, the robot computer then closes the MOTORS ON
relay to complete the circuit. When switching to MANUAL, the mode changes to
MOTORS OFF, at which stage the robot computer also opens the MOTORS ON relay. If
the robot mode does not change to MOTORS OFF, the ENABLE chain will break and the
ENABLE relay is opened. The safety circuit can thus be broken in two places by the robot
computer.
In any of the MANUAL modes, you can start operating again by pressing the enabling
device on the teach pendant. If the circuit is OK, the robot computer then closes the
MOTORS ON relay to complete the circuit. The function of the safety circuit can be
described as a combination of mechanical switches and robot computer controlled
relays which are all continuously monitored by the robot computer.
