E6581310 - 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'.

E6581310 f342 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 (f343) 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 (f343) is reverse direction regardless of FORWARD/REVERSE drive.
