Drive: Encoder Serial Number Changed; Drive: Angular Commutation Offset Transfer Running - Siemens Sinamics S120 Diagnostic Manual

207414 <location>Drive: Encoder serial number changed
Message value: -
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: ENCODER (NONE, OFF2)
Acknowledge: IMMEDIATELY
Cause: The serial number of the motor encoder of a synchronous motor has changed. The change was only checked for
encoders with serial number (e.g. EnDat encoders) and build-in motors (e.g. p0300 = 401) or third-party motors (p0300
= 2).
Cause 1:
The encoder was replaced.
Cause 2:
A third-party, build-in or linear motor was re-commissioned.
Cause 3:
The motor with integrated and adjusted encoder was replaced.
Cause 4:
The firmware was updated to a version that checks the encoder serial number.
Remedy: Re causes 1, 2:
Carry out an automatic adjustment using the pole position identification routine. Acknowledge the fault. Initiate the pole
position identification routine with p1990 = 1. Then check that the pole position identification routine is correctly exe-
cuted.
SERVO:
If a pole position identification technique is selected in p1980, and if p0301 does not contain a motor type with an
encoder adjusted in the factory, then p1990 is automatically activated.
or
Set the adjustment via p0431. In this case, the new serial number is automatically accepted.
or
Mechanically adjust the encoder. Accept the new serial number with p0440 = 1.
Re causes 3, 4:
Accept the new serial number with p0440 = 1.
207415 <location>Drive: Angular commutation offset transfer running
Message value: -
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: OFF2
Acknowledge: NONE
Cause: The angular commutation offset was automatically determined using p1990 = 1.
This fault causes the pulses to be suppressed - this is necessary to transfer the angular commutation offset to p0431.
See also: p1990 (Encoder adjustment, determine angular commutation offset)
Remedy: The fault can be acknowledged without any additional measures.
