The motor controller received the start
command from the programme unit, but did
not receive an interlock ACK (“Door locked”
signal).

If the power is on, be very careful when
working on the machine.

Switch off the machine for at least 30 seconds to
ensure the motor controller has been completely
reset. Then try to start the machine again. If the
error returns, troubleshoot as follows:

1. Measure the interlock signal on the motor controller
U1:X302.

No signal

Signal OK

Troubleshoot the motor
controller.

2. Measure the signal on interlock bus A1:X37 of the
programme unit.

No signal

Signal OK

Troubleshoot the cabling
between the motor
controller and programme
unit. Inspect the cabling and
replace if necessary.

Troubleshoot the interlock circuits.
