4. Diagnostics and Fault Clearance
4.2 Fault Diagnostics
The red „FAULT“ LED comes on. The fault messages appear in the
display. The fault messages must be cancelled with the red accept key
after the fault has been remedied (reset).
Cause:
Plug connector X7 on the CDR board in the control unit has been fitted
with an ADW2 analogue speed command value interface.
Remedy:
Switch off the control unit. Replace ADW2 with ADW3. Contact Indramat
customer service!
Cause:
Bleeder monitor has tripped due to overheating.
The bleeder in the control unit is faulty or no bleeder has been fitted.
Remedy:
Check whether the bleeder resistor in the upper part of the control unit
is faulty (visual inspection). If the bleeder is OK, then allow for the
cooling-down period (approximately 15 minutes).
If the control unit is not fitted with the "additional bleeder" option, <256>
is incorrectly contained in the value of FUNCT2 (A06).
Cause:
The limiting current in the control unit set on the electronic cut-out has
been exceeded.
Remedy:
Check the motor cable for a short-circuit or earth fault. Check the motor
for shorted windings or earth fault.
Cause:
Error on the CDR board.
Remedy:
Switch control unit off. Replace CDR board. Contact Indramat customer
service!
Cause:
The DC bus circuit is not charging up properly when the power contactor
is energized.
Remedy:
Check supply cable is securely connected to mains terminal.
Remove possible short-circuit in the DC bus circuit (L+,L-) (KDA/TDA
and RAC2 only).
Otherwise, contact Indramat customer service!
Cause:
Earth fault in motor cable or DC bus circuit.
Remedy:
Switch off control unit. Check motor cable (cabinet cable entry gland?)
and replace if necessary. Check motor. With KDA, check the DC bus
wiring.
