6.5.7.5 Setting the Motor Pre-excite time (FUN_53)
Pre-excitation refers to a process where power is supplied to the coils in the
motor to magnetize them before the motor rotation begins. Because pre-
excitation creates flux in a motor by magnetizing the coils and gets the motor
ready to run, it enhances motor’s acceleration response in a system where a
high starting torque is required.
During pre-excitation, the [FWD] and [REV] indicators flash simultaneously.
•
The pre-excite time set at FUN_53 is used only when FUN_02 (Spd Ref Sel)
is set to “Keypad1”, or “Keypad2”.

6.5.7.6 Zero-speed time after a stop (FUN_54)
FUN_54 (Hold time) is used to set the time for the motor to stay at the zero-
speed after a deceleration stop. When the motor is running a load with high
inertia, this function can prevent a motor movement by the residual inertia.
