p1226 Threshold for zero speed de‐
tection
0.00 210000.0
0
20.00 rpm Float IM T, U
Description: Sets the speed threshold for the standstill identification.
Acts on the actual value and setpoint monitoring.
●
When braking with OFF1 or OFF3, when the threshold is undershot, standstill is identified.
The following applies when the brake control is activated:
● When
the threshold is undershot, the brake control is started and the system waits for the brake closing
time in p1217. The pulses are then suppressed.
If the brake control is not activated, the following applies:
● When the threshold is undershot, the pulses are suppressed and the drive coasts down.
Dependency: p1215, p1216, p1217, p1227
p1227 Zero speed detection moni‐
toring time
0.000 300.000 300.000 s Float IM T, U
Description: Sets the monitoring time for the standstill identification.
When
braking with OFF1 or OFF3, standstill is identified after this time has expired, after the setpoint speed
has fallen below p1226.
After this, the brake control is started, the system waits for the closing time in p1217 and then the pulses
are suppressed.
Dependency: p1215, p1216, p1217, p1226
p1228 Pulse suppression delay
time
0.000 299.000 0.000 s Float IM T, U
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 activa‐
tion
- - 0000 bin - U16 IM T, U
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 processing
time.
Dependency: The individual speed setpoint filters are parameterized as of p1415.
