● Using the SBR (Safe Brake Ramp) function,
the inverter monitors whether the motor speed
decreases.
● The gradient of the SBR function can be
adjusted. The SBR function only starts after the
"Delay time for braking ramp". The SBR
function starts with the speed setpoint that was
applicable when SS1 was selected.
● When the standstill monitoring threshold is
fallen below, the inverter safely switches off the
motor torque (STO).
● The inverter monitors the motor speed using
the SAM (Safe Acceleration Monitor) function.
● The inverter prevents the motor from re-
accelerating by continuously adjusting the
monitoring threshold to the decreasing speed.
● The inverter reduces the monitoring threshold
until the "Shutdown speed" has been
reached.
● The inverter safely switches off the motor
torque (STO) if one of the following conditions
is fulfilled:
– The inverter detects that the motor is
stationary.
– The maximum time until the torque is
switched off has expired.
