OVC must not be enabled in hoisting applications.
3.20.3 B-2# Mechanical Brake
Parameters to configure the operation of an electro-magnetic (mechanical) brake, typically required in hoisting applications.
B-20 Release Brake Current
Range:
par. AP-37 [0.00 - par. AP-37 A]
A*
B-21 Activate Brake Speed [RPM]
Range:
0 RPM* [0 - 30000 RPM]
B-22 Activate Brake Speed [Hz]
Range:
0 Hz* [0.0 - 5000.0 Hz]
B-23 Activate Brake Delay
Range:
0.0 s* [0.0 - 5.0 s]
B-24 Stop Delay
Range:
0.0 s* [0.0 - 5.0 s]
B-25 Brake Release Time
Range:
0.20 s* [0.00 - 5.00 s]
B-26 Torque Ref
Range:
0.00 %* [0 - 0 %]
B-27 Torque Ramp Time
Range:
0.2 s* [0.0 - 5.0 s]
Function:
Set the motor current for release of the mechanical brake, when a start condition is present. The upper
limit is specified in par. DR-37 Drive Max. Current.
Function:
Set the motor speed for activation of the mechanical brake, when a stop condition is present. The upper
speed limit is specified in par. H-73 Warning Speed High.
Function:
Set the motor frequency for activation of the mechanical brake, when a stop condition is present.
Function:
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. See Mechanical Brake Control section in the AF-650 GP Design Guide.
Function:
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.
Function:
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.
Function:
The value defines the torque applied against the closed mechanical brake, before release
Function:
The value defines the duration of the torque ramp in clockwise direction.
