p0492 Maximum speed difference per sampling cycle / n_dif max/samp_cyc
VECTOR_G Can be changed: U, T
Data type: FloatingPoint32
P-Group: Encoder
Not for motor type: -
Min
0.00 [rpm]
Description: Sets the maximum permissible speed difference within the current controller sampling time.
Dependency: Refer to: r1408
Refer to: F07902, F31118, A31418, F32118, A32418, F33118, A33418
Note: For a value of 0.0, the speed change monitoring is disabled.
The following applies for square-wave encoders:
If the speed difference exceeds the threshold value p0492, depending on p0491, either encoderless closed-loop
speed/torque control is selected or the drive is switched off with fault F3x118.
The following applies for other speed encoders:
If the speed difference exceeds threshold value p0492, in order to avoid subsequent faults, the old speed actual
value is kept and after time p2178 shut down with fault F07902 (motor stalled).
p0492 Square-wave encoder maximum speed difference per sampling cycle /
n_dif max/samp_cyc
ENC Can be changed: U, T
Data type: FloatingPoint32
P-Group: Encoder
Not for motor type: -
Min
0.00 [rpm]
Description: Sets the maximum permissible speed difference within the current controller sampling time for squarewave
encoders.
Dependency: Refer to: F31118, A31418
Note: For a value of 0.0, the speed change monitoring is disabled.
if the set maximum speed difference is only exceeded for one sampling time of the current controller, then an
appropriate alarm is output. However, if the maximum speed difference is exceeded over several sampling times,
then a corresponding fault is output.
p0492 Square-wave encoder max. velocity difference per sampling cycle /
v_dif max/samp_cyc
ENC (Lin_enc) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Encoder
Not for motor type: -
Min
0.00 [m/min]
Description: Sets the maximum permissible velocity difference within the current controller sampling time for square-wave
encoders.
Dependency: Refer to: F31118, A31418
Note: For a value of 0.0, velocity change monitoring is disabled.
if the set maximum velocity difference is only exceeded for one sampling time of the current controller, then an
appropriate alarm is output. However, if the maximum speed difference is exceeded over several sampling times,
then a corresponding fault is output.
