Cause: Fault detected on the DRIVE-CLiQ component involved. Faulty hardware cannot be
excluded.
Fault value (r0949, hexadecimal):
20: Error in the telegram header.
23: Receive error: The telegram buffer memory contains an error.
42: Send error: The telegram buffer memory contains an error.
43: Send error: The telegram buffer memory contains an error.
Remedy: - check the DRIVE-CLiQ wiring (interrupted cable, contacts, ...).
- check the electrical cabinet design and cable routing for EMC compliance
- if required, use another DRIVE-CLiQ socket (p9904).
- replace the component involved.
230845 <location>Power module DRIVE-CLiQ: Cyclic data transfer error
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: A DRIVE-CLiQ communications error has occurred between the control unit and the power
module involved.
Fault value (r0949, hexadecimal):
0B: Synchronization error during alternating cyclic data transfer.
Remedy: Carry-out a POWER ON.
See also: p9916
230850 <location>Power module: Internal software error
Reaction: OFF1 (NONE, OFF2, OFF3)
Acknowledge: POWER ON
Cause: An internal software error in the power module has occurred.
Fault value (r0949, decimal):
1: Background time slice is blocked.
2: Checksum over the code memory is not OK.
3: The synchronization instant of the DSA link coincides with a compare interrupt.
4: Overflow of the software stack.
5: Overflow of the hardware stack (too many nested function calls or interrupts).
6: Program counter contains an invalid program address.
7: In the background, a global interrupt inhibit was detected.
Remedy: - replace power module.
- if required, upgrade the firmware in the power module.
- contact the Hotline.
230851 <location>CU DRIVE-CLiQ: Sign-of-life missing
Reaction: OFF2 (NONE, OFF1, OFF3)
Acknowledge: IMMEDIATELY
Cause: A DRIVE-CLiQ communications error has occurred between the control unit and the power
module involved. The DRIVE-CLiQ component did not set the sign of life to the control unit.
Fault value (r0949, hexadecimal):
0A: The sign-of-life bit in the receive telegram is not set.
Remedy: - upgrade the firmware of the component involved.
230860 <location>CU DRIVE-CLiQ: Telegram error
Reaction: OFF2
Acknowledge: IMMEDIATELY
