Incorrect Direction Of Rotation Of The Encoder Actual Value Inversion; Drive: Pole Position Identification Not Successful - Siemens Sinamics S120 Diagnostic Manual

207993 <location>Drive: Incorrect direction of rotation of the field or encoder actual value
inversion
Message value: -
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY
Cause: Either the direction of the rotating field or the encoder actual value has an incorrect sign. The motor data identification
automatically changed the actual value inversion (p0410) in order to correct the control sense. This can result in a
direction of rotation change. To acknowledge this fault, the correctness of the direction of rotation must first be
acknowledged with p1910 = -2.
Remedy: Check the direction of rotation, also for the position controller, if one is being used.
If the direction of rotation is correct, the following applies:
No additional measures are required (except p1910 = -2 and acknowledge fault).
If the direction of rotation is incorrect, the following applies:
To change the direction of rotation, two phases must be interchanged and the motor identification routine must be
repeated.
207995 <location>Drive: Pole position identification not successful
Message value: %1
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The pole position identification routine was unsuccessful.
Fault value (r0949, interpret decimal):
1: No current is established.
2: The starting current is not zero.
3: The selected max. distance was exceeded (p1981).
4x: The measuring signal does not permit a clear evaluation.
5: The max. current was exceeded during the measurement.
6: The current measurement must be re-calibrated.
7x: The Sensor Module does not support the pole position identification routine.
8: The pole position identification routine current required is greater than the max. current.
9: The set pole position identification routine current is zero.
10: Data set changeover during the pole position identification.
11: The encoder adjustment to determine the commutation angle (p1990 = 1) and the encoder without zero mark is
not finely synchronized or does not have any valid data.
100: Motion-based pole position identification, 1st and 2nd measurement different. Motor locked or current (p1993)
too low.
101: Motion-based position position identification, insufficient motion, motor locked or current (p1993) too low.
102: Motion-based pole position identification, brake is being used and is closed. The motion-based position position
identification in conjunction with the brake is not permitted.
103: Motion-based pole position identification without encoder.
104: Motion-based pole position identification, speed actual value not zero after stabilizing time.
Note: x = 0 ... 9
