Delay time
The SBR function only starts after an adjustable time. To begin with, the inverter monitors the
speed setpoint that applied when SS1 was selected.
Braking
The inverter brakes the motor with the OFF3 ramp-down time.
Shutdown speed
The inverter safely switches off the motor torque using the STO function if the speed has
reached the shutdown speed.

r9722.1
Status signals
1 signal: SS1 active
r9714
Speed diagnostics [rpm]
[0] Load-side speed actual value
Electrical speed of the motor. For induction motors, the mechanical speed is ob‐
tained from the electrical speed and slip.
[1] Actual SAM/SBR speed limit
r9723.16
1 signal: SAM/SBR active
p1135
OFF3 ramp-down time
p1226
Standstill detection, speed threshold (Fac‐
tory setting: 20 rpm)
The inverter switches off the motor torque
if the speed either fulfills the condition for
standstill detection or the shutdown
speed p9569 has been reached.
p1227
Standstill detection monitoring time (Value
depends on the power unit)
