Startup of Standard Design

Bus operation

The mechanical brake is controlled by the relay output.

A braking resistor (BW..) must be connected to terminal 13 and 15 at the wiring board
of MOVIMOT

®

, terminal 14 is not assigned.

The relay functions as brake control relay so that the ready signal function is no long-
er available (it is imperative that you observe section "Use of relay output with special
function 7 + 9" starting on page 75).

The new function "Brake applied at down ramp" is introduced. Bit 9 in the control
word is assigned with this function as virtual terminal according to MOVILINK

®

pro-

file.

As soon as bit 9 is set during the down ramp, the relay output applies the brake and
MOVIMOT

®

inhibits the output stage.

If the motor frequency is lower than the stop frequency, the brake is applied indepen-
dent of the status of bit 9.

Terminal operation

The mechanical brake is controlled by the relay output.

A braking resistor (BW..) must be connected to terminal 13 and 15 at the wiring board
of MOVIMOT

®

, terminal 14 is not assigned.

The relay functions as brake control relay, so that the ready signal function is no long-
er available.

Applying the brake via bit 9 cannot be used in terminal operation.
