SINAMICS G120 Control Units CU240S, Edition 05/2007
Remedy: • r0949 = 100 or 200
Increase the ramping times p1120/p1121 or the safety tolerance p9691/p9891,
check the motor parameters (p0394 - p0311) or run the motor identification (p1910) again.
Decrease the rate of switching the safety signals or lower the cycle time of the PLC.
• r0949 = 101 or 201
Increase the ramping times p1120/p1121 or the safety tolerance p9691/p9891,
check the motor parameters (p0394 - p0311) or run the motor identification (p1910) again.
• r0949 = 102 or 202
Increase the ramping times (p1120, p1121) so that deviation between reference and actual frequency is mini-
mized.
Increase the safety tolerance p9691/p9891 or run the motor identification (p1910) again for better tuning of the
observer and controllers.
• r0949 = 104 or 204
Acknowledge the fault once more
Power cycle the CU
• r0949 = 106 or 206
Check connection with safe brake module and mechanical brake
Check the 24 V power supply for safe brake module
• r0949 = 107 or 207
Check connection between CU and power module
Power cycle the CU
• r0949 = , 108, or 208
Decrease the rate of switching the safe digital inputs or increase debounce delay time p9650/p9850.
• r0949 = 109 or 209
Power cycle the CU
