Parameter Descriptions
2-16 AC Brake, Max current
Range: Function:
100 % [0 - Enter the maximum allowed current when
*
160 %] using AC brake to avoid overheating of
motor windings.
NOTICE
Parameter 2-16 AC Brake, Max current
is only available for asynchronous
motors.
2-17 Over-voltage Control
Option: Function:
Overvoltage control (OVC) reduces the risk of
the frequency converter tripping due to an
overvoltage on the DC link caused by
generative power from the load.
[0] Disabled No OVC required.
*
[1] Enabled Activate OVC except when using a stop signal
(not at to stop the frequency converter.
stop)
[2] Enabled Activate OVC.
CAUTION
PERSONAL INJURY AND
EQUIPMENT DAMAGE
Enabling OVC in hoisting applications
may lead to personal injuries and
equipment damage.
•
DO NOT enable OVC in hoisting
applications.
2-19 Over-voltage Gain
Range:
100 % [0 - 200 %]
*

4.3.3 2-2* Mechanical Brake
2-20 Release Brake Current
Range: Function:
0 A [0 - 100 Set the motor current for release of the
*
A] mechanical brake when a start condition is
present. The upper limit is specified in
parameter 16-37 Inv. Max. Current.
NOTICE
When mechanical brake control output is
selected, but no mechanical brake is
connected, the function does not work by
default setting due to too low motor
current.
2-22 Activate Brake Speed [Hz]
Range: Function:
0 Hz [0 - 400 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 0 speed
with full holding torque. Ensure that the
mechanical brake has locked the load before the
motor enters coast mode.
