• DOK-DIAX01-MAIN+2AD+1M-ANW1-EN-E1,44 • 07.97
Cause:
• Broken connection between motor temperature sensor and control
unit, or faulty temperature sensor (signal appears approximately ten
minuates after fault occurs).
Remedy:
• Check temperature sensor connections.
• If sensor is faulty, contact Indramat customer service!
Note: see Section 3.11
Cause:
Software in programming module does not match control unit.
Remedy:
Use a programming module which matches the control unit. Contact
Indramat customer service.
Cause:
The control unit's 8V supply is faulty.
Remedy:
Contact Indramat customer service.
Cause:
The ± 15V supply of the control unit is faulty.
Remedy:
• Check bus connecting cable (in KDA)
• Contact INDRAMAT customer service (with RAC)
Cause:
The ± 24V supply of the control unit is faulty.
Remedy:
• Check bus connecting cable (in KDA)
• Contact INDRAMAT customer service (with RAC)
Cause:
No external voltage for the control inputs and signal outputs (X2/1 and
19), incorrect polarity or outside the tolerance range.
Remedy:
• Check connections and voltage of external +24V supply. The voltage
level must be between 18V and 36V. If the external +24V is OK, the
fault message is cancelled automatically.
• If the external +24V is absent, the control unit's internal +24V/OV
supply can also be used (link +24Vint/OVint to +24Vext/OVext on X2!).
Note: see Section 3.1
Cause:
The mains voltage exceeds the rated device voltage by more than 15%.
The power contactor in the unit cannot be engaged.
Remedy:
Check mains conditions. If necessary, use transformer to match mains
voltage.
