SINAMICS S110 List Manual (LH7), 06/2012, 6SL3097-4AP10-0BP3
Note:
This fault does not result in a safety stop response.
Remedy: When safety functions are enabled (p9501 <> 0 and/or p9601 <> 0):
1. Activate the "Firmware update automatic" function (p7826 = 1).
2. Save the parameters (p0977 = 1) and carry out a POWER ON.
When de-activating the safety functions (p9501 = 0, p9601 = 0), the fault can be acknowledged after exiting the
safety commissioning mode.
F01665 SI CU: System is defective
Message value: %1
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: A system defect was detected before the last boot or in the actual one. The system might have been rebooted (reset).
Fault value (r0949, interpret hexadecimal):
200000 hex, 400000 hex, 8000yy hex (yy any):
- Fault in the actual booting/operation.
800004 hex:
- Parameters p9500/p9300 are, under certain circumstances, not the same. In addition, Safety message
C01711/C30711 is displayed.
Additional values:
- defect before the last time that the system booted.
Remedy: - carry out a POWER ON (power off/on).
- upgrade firmware to later version.
- contact the Hotline.
Re fault value = 200000 hex, 400000 hex, 8000yy hex (yy any):
- ensure that the Control Unit is connected to the Power Module.
Re fault value = 800004 hex:
- Check that parameters p9500/p9300 are the same.
A01666 (F) SI Motion CU: Steady-state (static) 1 signal at the F-DI for safety-relevant acknowl-
edgement
Message value: -
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: NONE
Acknowledge: NONE
Cause: A logical 1 signal is present at the F-DI configured in p10006 for more than 10 seconds.
If, at the F-DI no acknowledgment was performed for safe acknowledgment, then a steady-state logical and 0 signal
must be present. This avoids unintentional safety-relevant acknowledgement (or the "Internal Event Acknowledge"
signal) if a wire breaks or one of the two digital inputs bounces.
Remedy: Set the fail-safe digital input (F-DI) to a logical 0 signal (10006).
Note:
F-DI: Failsafe Digital Input
Reaction upon F: NONE
Acknowl. upon F: IMMEDIATELY
A01669 (F, N) SI Motion: Unfavorable combination of motor and power unit
Message value: %1
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: NONE
Acknowledge: NONE
Cause: The combination of motor and power unit used is not suitable for using safe motion monitoring functions without an
encoder.
Alarm value (r2124, interpret decimal):
Number of the motor data set, which caused the fault.
Remedy: Use a suitable power unit with a lower power rating or a motor with a higher power rating.
Reaction upon F: NONE (OFF1, OFF2, OFF3)
Acknowl. upon F: IMMEDIATELY (POWER ON)
