Startup of Standard Design
"Rapid start" partial
function Regardless of whether MOVIMOT
®
is controlled in terminal or bus operation, the pre-
magnetization is fixed at 0 s, i.e. pre-magnetization does not take place at the beginning
of the release to start accelerating at the setpoint ramp as quickly as possible.
"Rapid stop" partial
function The new function "Brake applied at down ramp" is introduced in bus operation. Bit 9 is
assigned with this function as virtual terminal in the control word.
As soon as bit 9 is set during the down ramp, MOVIMOT
®
directly applies the brake
(brake control is carried out through MOVIMOT
®
) or via the MOVIMOT
®
signal relay out-
put (brake control is carried out through relay output) and blocks the output stage.
If the motor frequency is lower than the stop frequency (3 Hz), the brake is applied in-
dependent of the status of bit 9 during the down ramp.

In terminal operation, the rapid stop function via control word bit 9 is not
available.
