Danfoss FC 300

2-24 Stop delay
Range: Function:
0.0 s
*
[0.0 - 5.0 s] Set the time interval from the moment when the motor is stop-
ped until the brake closes. This parameter is a part of the
stopping function.
2-25 Brake Release Time
Range: Function:
0.20 s
*
[0.00 - 5.00 s] This value defines the time it takes for the mechanical brake to
open/ close. This parameter must act as a time-out when brake
feedback is activated.
2-26 Torque Ref
Range: Function:
0.00%
*
[-100.00 - 100.00 %] The value defines the torque applied against the closed me-
chanical brake, before release
2-27 Torque Ramp Time
Range: Function:
0.2 s
*
[0.0 - 5.0 s] The value defines the duration of the torque ramp in clockwise
direction.
2-28 Gain Boost Factor
Range: Function:
1.00
*
[0.00 - 4.00] When a speed PID-control is connected to the output (flux
closed loop) it must be possible to boost the proportional gain
of the control during the
Activate Brake Delay (par. 2-23). By
increasing the gain, the bump when the motor takes over the
load from the brake can be reduced. The risk of oscillation is
very small due to the relatively short duration and the low (zero)
speed.
