Description: Sets the speed threshold for the standstill identi󹪝cation.
Acts on the actual v
alue and setpoint monitoring.
When braking with OFF1 or OFF3, when the threshold is undershot, standstill is identi󹪝ed.
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.

NOTICE
For reasons relating to the compatibility to earlier 󹪝rm
war
e 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
Stands
till is identi󹪝ed 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 identi󹪝cation.
When braking
with OFF1 or OFF3, standstill is identi󹪝ed 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.
