44.08 Brake open delay
0.00 ... 5.00 s
Description
Activates/deactivates (or selects a source that
activates/deactivates) the mechanical brake control logic.
0 = Brake control inactive
1 = Brake control active
0.

Digital input DI1 (10.02 DI delayed
Digital input DI2 (10.02 DI delayed
Digital input DI3 (10.02 DI delayed
Digital input DI4 (10.02 DI delayed
Digital input DI5 (10.02 DI delayed
Digital input DI6 (10.02 DI delayed
Digital input/output DIO1

Activates/deactivates (and selects the source for) brake
open/close status (acknowledgment) supervision.
When a brake control error (unexpected state of the
acknowledgment signal) is detected, the drive reacts as
defined by parameter 44.17 Brake fault function.
0 = Brake closed
1 = Brake open
0.

Source selection (see Terms and abbreviations

Defines the brake open delay, i.e. the delay between the
internal open brake command and the release of motor
speed control. The delay timer starts when the drive has
magnetized the motor and increased the motor torque to the
level required for brake release (parameter
open torque reference). Simultaneously with the timer start,
the brake control logic energizes the brake control output
and the brake starts to open.
Set this parameter to the value of mechanical opening delay
specified by the brake manufacturer.
