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: Refer to: p1215, p1216, p1217, p1227
Notice: For reasons relating to the compatibility to earlier firmware versions, a parameter value of zero in indices 1 to 31 is
overwritten with the parameter value in index 0 when the Control Unit boots.
Note: 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.
The actual value sensing is subject to measuring noise. For this reason, standstill cannot be detected if the speed
threshold is too low.
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 (also refer to p1145).
After this, the brake control is started, the system waits for the closing time in p1217 and then the pulses are
suppressed.
Dependency: Refer to: p1215, p1216, p1217, p1226
Notice: For p1145 > 0.0 (RFG tracking) the setpoint is not equal to zero dependent on the selected value. This can therefore
cause the monitoring time in p1227 to be exceeded. In this case, for a driven motor, the pulses are not suppressed.
Note: 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.
For p1227 = 300.000 s, the following applies:
Monitoring is de-activated.
For p1227 = 0.000 s, the following applies:
With OFF1 or OFF3 and a ramp-down time = 0, the pulses are immediately suppressed and the motor "coasts" down.
Description: Sets the delay time for pulse suppression.
After OFF1 or OFF3, the pulses are canceled, if at least one of the following conditions is fulfilled:
- the speed actual value falls below the threshold in p1226 and the time started after this in p1228 has expired.
- the speed setpoint falls below the threshold in p1226 and the time started after this in p1227 has expired.
Dependency: Refer to: p1226, p1227
Notice: When the motor holding brake is activated, pulse cancellation is additionally delayed by the brake closing time
(p1217).
