Description
The drive reports warning 101, Speed monitor when the speed is outside the limit.
The drive trips and reports alarm 101, Speed monitor.
The drive 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 op-
tion is available in closed loop only. The drive trips and reports alarm 101, Speed monitor in run-
ning mode. In stop mode, the drive catches the flying load and reports warning 101, Speed moni-
tor. In catch mode, the drive applies holding torque to control the 0 speed on a potentially mal-
functioning brake (closed loop). To exit this mode, send a new start signal to the drive. A coast or
Safe Torque Off also terminates the function.
