2-20 Release Brake Current
Range: Function:
Size
related*
[ 0 - 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:
Size
related*
[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:
Size related* [ 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 s* [0 - 5 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
mechanical brake has locked the load before the
motor enters coast mode.
2-24 Stop Delay
Range: Function:
0 s* [0 - 5 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 - 5 s] This value defines the time it takes for the
mechanical brake to open. This parameter
must act as a timeout when brake feedback is
activated.
2-26 Torque Ref
Range: Function:
0 %* [ 0 - 0 %]
2-27 Torque Ramp Up Time
Range: Function:
0.2 s* [0 - 5 s] The value defines the duration of the torque
ramp in clockwise direction.
2-28 Gain Boost Factor
Range: Function:
1 * [0 - 4 ] 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.
