2-20 Release Brake Current
Range: Function:
par.
16-37 A*
[0.00 -
par. 16-37
A]
Set the motor current for release of the
mechanical brake, when a start condition is
present. The default value is the maximum
current the inverter can provide for the
particular power size. The upper limit is
specified in 16-37 Inv. Max. Current.
NOTICE
When Mechanical brake control
output is selected but no mechanical
brake is connected, the function will
not work by default setting due to
too low motor current.
2-21 Activate Brake Speed [RPM]
Range: Function:
0 RPM* [0 - 30000
RPM]
Set the motor speed for activation of the
mechanical brake, when a stop condition
is present. The upper speed limit is
specified in 4-53 Warning Speed High.
2-22 Activate Brake Speed [Hz]
Range: Function:
0 Hz* [0.0 - 5000.0 Hz] Set the motor frequency for activation
of the mechanical brake, when a stop
condition is present.
2-23 Activate Brake Delay
Range: Function:
0.0 s* [0.0 - 5.0
s]
Enter the brake delay time of the coast after
ramp-down time. The shaft is held at zero
speed with full holding torque. Ensure that the
2-23 Activate Brake Delay
Range: Function:
mechanical brake has locked the load before
the motor enters coast mode.
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 stopped 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. This parameter
must act as a time-out when brake
feedback is activated.
2-26 Torque Ref
Range: Function:
0.00 %* [0 - 0 %] The value defines the torque applied against
the closed mechanical 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
N/A*
[1.00 -
4.00 N/A]
Only active in flux closed loop. The
function ensures a smooth transition
from torque control mode to speed
control mode when the motor takes over
the load from the brake.
