limit.
The frequency converter trips and reports
alarm 101, Speed monitor.
The frequency converter reports alarm 101,
Speed monitor in running mode and warning
101, Speed monitor in stop or coast mode. This
option is only available in closed-loop
operation.
Select when there is a need to catch a load,
for example when mechanical braking fails.
This option is available in closed loop only.
The frequency converter trips and reports
alarm 101, Speed monitor in running mode. In
stop mode, the frequency converter catches
the flying load and reports warning 101, Speed
monitor.
In catch mode, the frequency converter
applies holding torque to control the zero
speed on a potentially malfunctioning brake
(closed loop). To exit this mode, send a new

[1] Speed Enables speed closed-loop control with
closed feedback. Obtain full holding torque at 0 RPM.
