Explanation of braking setting function
At starting the motor:
When the operation signal is ‘ON’, the brake release signal is ‘ON’ after getting the flux of magnetic induction before brake releasing.
The output torque of inverter is generated before the brake is released by outputting ‘the frequency of the 
setting’ to ‘the direction of the 
setting’.
The motor is able to accelerate smoothly at the same time as releasing the brake because 
function provides ‘the delay of acceleration beginning ‘.
At stop the motor:
When the operation signal is ‘OFF’, the brake close signal is ‘ON’ after reaching the creeping frequency of 
setting. After that, the VF-S11 outputs creeping frequency while setting time of 
, and stops after delayed time of mechanical brake.
Braking mode selection
0: Disabled
1: Enabled (forward run)
The rise operation is forward rotation of motor at RISE/DESCENT action.
The direction of inverter output frequency (
) is forward direction regardless of FORWARD/REVERSE drive.
2: Enabled (reverse run)
The rise operation is reverse rotation of motor at RISE/DESCENT action.
The direction of inverter output frequency () is reverse direction regardless of FORWARD/REVERSE drive.
3: Enabled (operating direction)
This value is for the horizontal operation.
The direction of inverter output frequency () is same as direction of drive.
Release frequency
The inverter outputs ‘s frequency to ‘s direction. This function is for generating motor torque by slipping of the restrained motor. By this, the motor starts smoothly when the brake is released.
The setting value depends on load condition. The standard setting is ‘the slipping frequency’ at rated output of applied motor.
Release time
The release time is time to maintain frequency of setting at start.
The standard setting is delayed time of mechanical brake.
Creeping frequency
The ‘close brake signal’ outputs ‘s frequency while 
‘s setting time at stop.
The setting value depends on load condition. The standard setting is
The setting value depends on load condition. The standard setting is ‘the slipping frequency’ at rated output of applied motor
Creeping time
The creeping time is time to maintain frequency of .
The standard setting is a little more than delayed time of mechanical brake.
