Re fault value = 9:
Enter a value not equal to zero in the pole position identification routine current (p0329, p0325,
p1993).
Re fault value = 10:
Do not initiate a data set changeover during the pole position identification.
Re fault value = 11:
- for incremental encoders without commutation with zero mark (p0404.15 = 0), it does not make
sense to adjust the encoder to determine the commutation angle (p1990 = 1). In this case, the function
should be de-selected (p1990 = 0) or, for an encoder with suitable zero mark, commutation with zero
mark should be selected (p0404.15 = 1).
- for absolute encoders, only adjust the encoder to determine the commutation angle (p1990 = 1) if
the encoder supplies commutation information and is finely synchronized (p1992.8 = 1 and p1992.10
= 1). The encoder is possibly parked, de-activated (p0145), not ready to operate or signals a fault con-
dition.
- deselect the encoder adjustment to determine the commutation angle (set p1990 to 0).
Re fault value = 100, 101:
Check and ensure that the motor is free to move.
Increase the current for motion-based pole position identification (p1993).
Re fault value = 102:
If the motor is to be operated with a brake: Select a different technique to identify the pole position
(p1980).
If the motor can be operated without a brake: Open the brake (p1215 = 2).
Re fault value = 103:
The motion-based pole position identification can only be carried out using an encoder. Connect an
encoder or select another technique for pole position identification routine (p1980).
Re fault value = 104:
Pole position identification, increase the smoothing time, motion-based (p1997).
Pole position identification, increase the rise time, motion-based (p1994).
Pole position identification, check the gain, motion-based (p1995).
Pole position identification, check the integral time, motion-based (p1996).
207996 <location>Drive: Pole position identification routine not carried out
Message -
value:
Drive object: SERVO
Reaction: ENCODER (OFF2)
Acknowledge: IMMEDIATELY
Cause: In operation, the operating mode that requires a pole position identification was changed over, which
is not possible in this state:
- the drive was changed over, flying, from encoderless operation to operation with encoder without
having previously carried out a pole position identification for the encoder. p1404 is then at a value
between zero and the max. speed and the pulses in the speed range above p1404 were enabled with-
out a pole position ident. routine having been previously carried out in operation with encoder.
- in operation, an EDS changeover was made to an encoder where it is necessary to carry out a pole
position identification. However, this has still not been carried out (p1982 = 1 or 2 and p1992.7 = 0).
Remedy: - for a flying changeover between operation with and without encoder with pole position identification
after POWER ON or commissioning (p0010 not equal to zero) enable the pulses once at zero speed.
This means that the pole position identification routine is carried out and the result is available for oper-
ation.
- carry out the EDS changeover with the pulses inhibited, or, before the changeover, carry out a pole
position identification using this data set.
