Par. No. Name
Description: Sets the delay time for pulse suppression.
After OFF1 or OFF3 and zero speed detection, the system waits for this time to expire and the pulses are
then suppressed.
Standstill is identified in the following cases:
The speed actual value falls below the speed threshold in p1226 and the time started after this in p1228
•
has expired.
The speed setpoint falls below the speed threshold in p1226 and the time started after this in p1227 has
•
expired.
Dependency: p1226, p1227
p1414 Speed setpoint
filter activation
Description: Setting for activating/de-activating the speed setpoint filter.
If only one filter is required, filter 1 should be activated and filter 2 de-activated, to avoid excessive pro-
cessing time.
Dependency: The individual speed setpoint filters are parameterized as of p1415.
p1415 Speed setpoint
filter 1 type
Description: Sets the type for speed setpoint filter 1.
0: Low pass: PT1
•
1: Low pass: PT2
•
2: General 2nd-order filter
•
Dependency:
PT1 low pass: p1416
•
PT2 low pass: p1417, p1418
•
General filter: p1417 ... p1420
•
p1416 Speed setpoint
filter 1 time con-
stant
Description: Sets the time constant for the speed setpoint filter 1 (PT1).
This parameter is only effective if the filter is set as a PT1 low pass.
Dependency: p1414, p1415
p1417 Speed setpoint
filter 1 denomi-
nator natural
frequency
Description: Sets the denominator natural frequency for speed setpoint filter 1 (PT2, general filter).
This parameter is only effective if the speed filter is parameterized as a PT2 low pass or as general filter.
The filter is only effective if the natural frequency is less than half of the sampling frequency.
Dependency: p1414, p1415
p1418 Speed setpoint
filter 1 denomi-
nator damping
Description: Sets the denominator damping for velocity setpoint filter 1 (PT2, general filter).
This parameter is only effective if the speed filter is parameterized as a PT2 low pass or as general filter.
Dependency: p1414, p1415
p1419 Speed setpoint
filter 1 numerator
