TROUBLESHOOTING
E-21
Faulty stepper motors Signalization input: PLC-A input
1.01
Fault
Cause
Troubleshooting
Red light on/flashing at
some of stepper motor
driver.
1. Driver signaling breakdown.
Switch the machine off for more than 1
min and switch it on again. In case the
drive still shows a problem, replace off for
driver 12.0010.4.161, or call the service.
ATTENTION - drivers can be
interchangeable, but they have different for
individual axes (driver controllers).
Green light on at all
stepper motor drives.
1. Drivers signaling circuit disconnected.
Check correct connection or plug-in of
connectors and line wires to drivers.
Signalization PLC-A input 1.01.
2. Faulty PLC input
Check signal on PLC-A input, replace PLC
06.8015.0.001.
E-30
Communication error between PLC-A and PLC-B
Fault
Cause
Troubleshooting
For Ultraflex or Indexer
version only.
Loss of communication
between PLC-A and
PLC-B
1. Communication cable between PLCs
disconnected
Check correct connection or plug-in of
cable connectors into PLC communication
block. Yellow control light COMM must be
flashing on all communication block.
2. Faulty cable between PLCs
Repair / replace 06.1500.0.052.
3. Faulty communication block on PLC
Replace block 12.0010.4.067.
3.2. FAULTS THAT SHOWS ONCE MACHINE IS STARTED
Fault
Cause
Troubleshooting
Machine is switched on
with the power switch,
but the table light and
display does not light
up, the ventilator in the
control box does not
work.
1. Power supply is not connected.
Check connection cord or voltage is
socket. ATTENTION - line voltage!
2. Power supply cord faulty
Change cable 12.0008.4.885.
ATTENTION - line voltage!
3. Power contactor QS1 faulty
Replace contactor 12.0010.4.200.
ATTENTION - line voltage!
Machine is switched on
with the powr switch,
but the table light and
display does not light
up. The ventilator in
the control box works.
Green control light in
control box at GS1
source is not on.
1. Fuse F2 - T2A
Replace fuse 12.0008.4.665. ATTENTION
- line voltage!
2. GS1 - 24V source faulty
Replace source 12.0010.4.168.
ATTENTION - line voltage!
3. Power supply 24V short circuit
Necessary to remove short circuit - find
the circuit place by disconnection one part
after another (PLC, display, connectors
X7,X8,X9) and troubleshoot.
The ventilator in the
control box does not
work, but the table light
and display are on.
1. Fuse F1 - T2A burnt
Replace fuse 12.0008.4.665.
ATTENTION - line voltage!
2. Faulty ventilator EV2
Replace ventilator 12.0008.4.682.
ATTENTION - line voltage!
