SINAMICS alarms
207320 <location>Drive: Automatic restart interrupted
Message value: %1
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SERVO_COMBI, SERVO_SINUMERIK828, SIC_COMBI,
SIC_SINUMERIK_828
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: - The specified number of restart attempts (p1211) has been completely used up because within the monitoring time
(p1213) the faults were not able to be acknowledged. The number of restart attempts (p1211) is decremented at each
new start attempt.
- there is no active ON command.
- the monitoring time for the power unit has expired (p0857).
- when exiting commissioning or at the end of the motor identification routine or the speed controller optimization, the
drive unit is not automatically powered up again.
Fault value (r0949, interpret hexadecimal):
Only for internal Siemens troubleshooting.
Remedy: - increase the number of restart attempts (p1211). The actual number of starting attempts is displayed in r1214.
- increase the delay time in p1212 and/or the monitoring time in p1213.
- issue an ON command (p0840).
- either increase or disable the monitoring time of the power unit (p0857).
207321 <location>Drive: Automatic restart active
Message value: -
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SERVO_COMBI, SERVO_SINUMERIK828, SIC_COMBI,
SIC_SINUMERIK_828
Reaction: NONE
Acknowledge: NONE
Cause: The automatic restart (AR) is active. When the line supply returns and/or the causes of the existing faults are removed
the drive is automatically restarted. The pulses are enabled and the motor starts to rotate.
Remedy: - the automatic restart (AR) should, if required, be inhibited (p1210 = 0).
- an automatic restart can be directly interrupted by withdrawing the power-on command (BI: p0840).
207329 <location>Drive: kT estimator, kT(iq) characteristic or voltage compensation does not
function
Message value: %1
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: NONE
Acknowledge: NONE
Cause: A function of the function module "extended torque control" (r0108.1) was activated - however the (complete) function
is not available.
Fault value (r0949, interpret decimal):
1 ... 3: The kT estimator is active (p1780.3 = 1) without a functioning compensation of the voltage emulation error in
the drive converter. This means that the accuracy is severely restricted.
1: The drive converter voltage emulation error "final value" is 0 (p1952).
2: The drive converter voltage emulation error "current offset" is 0 (p1953).
3: The compensation of the voltage emulation error is disabled (p1780.8 = 0).
4: The kT estimator (p1780.3 = 1), the kT(iq) characteristic (p1780.9 = 1) or the compensation of the voltage emulation
error (p1780.8 = 1) was activated without activating the function module "extended torque control" (when the function
module is activated, the following must apply: r0108.1 = 1).
