Braking time learning function
f325
: Brake releasing waiting time
The brake release request signal is not output during f325 (Brake releasing waiting time)
setting time when the brake release.
The function is disabled when f325=0.00.
f326
: Brake releasing small current detection level
The inverter trip as low-current operation fault (uc) if the output current is f326 or less after
a lapse of f325 setting time when the brake release.
The function is disabled when f326=0.
f340
: Creeping time 1
Inverter suspends the braking request for the time set with f340 to minimize swing of load.
f341
: Braking mode selection
This parameter is to select operation mode of brake sequence function.
Usually, the forward (Terminal F) operation is winding up.
f342
: Load portion torque input selection
This parameter is to set the brake releasing torque value balanced with the load torque to
prevent load gap (shifts) at brake release.
Usually, set f342 = 4, and set the fixed value to f343 (Hoisting torque bias input) .
f343
: Hoisting torque bias input
This parameter is to set hoisting torque bias value and enabled only when f342 = 4.
The 100% value is the motor rated torque determined by f405 (Motor rated capacity) and
f417 (Motor rated speed).
Usually, set f343 =100. In case of trouble after brake learning, adjust this setting value.
