- 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
f343 setting' to 'the direction of the f342 setting'.
The motor is able to accelerate smoothly at the same time as releasing the brake because f344
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
f345 setting. After that, the VF-S11 outputs creeping frequency while setting time of f346, and stops
after delayed time of mechanical brake.
