Mechanical brake controlled by MOVIMOT
®
:
•
Terminals 13, 14 and 15 are assigned to the brake coil of the mechanical brake at
the wiring board of MOVIMOT
®
.
•
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, MOVIMOT
®
applies the brake and in-
hibits 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.
•
The relay is switched as ready relay (standard function).
Mechanical brake controlled by 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.
