Overview of Alarms
SINAMICS-Alarms
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 current number of starting attempts is dis-
played 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: A_INF, B_INF, S_INF, SERVO, VECTOR
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 %1
value:
Drive object: SERVO
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 emu-
lation 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).
Remedy: Re fault value = 1, 2:
- carry out an identification of the voltage emulation error in the drive converter (p1909.14 = 1, p1910
= 1).
- set the parameter to compensate the voltage emulation error in the drive converter (p1952, p1953).
Re fault value = 3:
- enable the compensation of the voltage emulation error in the drive converter (p1780.8 = 1).
Re fault value = 4:
- activate the function module "extended torque control" (r0108.1 = 1) or de-activate the corresponding
functions (p1780.3 = 0, p1780.8 = 0, p1780.9 = 0).
207330 <location>Flying restart: Measured search current too low
Message -
value:
Drive object: VECTOR
Reaction: OFF2 (NONE, OFF1)
Acknowledge: IMMEDIATELY
