Par. No. Name
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.
p1227 Zero speed detection
monitoring time
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: Refer to p1215, p1216, p1217, p1226
Notice: The setpoint is not equal to zero dependent on the selected value. This can therefore cause the moni-
toring 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.
p1228 Pulse suppression delay
time
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 ex-
pired.
- 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).
p1414 Speed setpoint filter acti-
vation
Description: Setting for activating/de-activating the speed setpoint filter.
Dependency: The individual speed setpoint filters are parameterized as of p1415.
Note: The drive unit displays the value in hex format. To know the logic (high/low) assignment to each bit, you
must convert the hex number to the binary number, for example, FF (hex) = 11111111 (bin).
p1415 Speed setpoint filter 1
type
Description: Sets the type for speed setpoint filter 1.
Dependency:
PT1 low pass: p1416
PT2 low pass: p1417, p1418
General filter: p1417 ... p1420
