A.3 Parameters
p1226[0]
Threshold for zero speed detection
Data type: FloatingPoint32
Read permission:
Write permission:
Can be changed in the operating
state:
Parameter group:
Unit: rpm
Min:
0.00 [rpm]
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 canceled.
if the brake control is not activated, the following applies:
When the threshold is undershot, the pulses are canceled and the drive coasts down.
Dependency:

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.
p1227[0]
Zero speed detection monitoring time
Data type: FloatingPoint32
Read permission:
Write permission:
Can be changed in the operating
state:
Parameter group:
Unit: s
Min:
0.000 [s]
Description:
Sets the monitoring time for the standstill identification.
When braking with OFF1 or OFF3, standstill is identified after the time set here 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 canceled.
