 In the diagram shown below, the Acceleration/Deceleration Time of the AC drive is time

between 0 Hz to Maximum Output Frequency (Pr.01-00). Suppose the Maximum Output

Frequency is 60 Hz, Minimum Output Frequency (Pr.01-05) is 1.0 Hz, and

Acceleration/Deceleration Time is 10 seconds. The actual time for the AC drive to

accelerate from start-up to 60 Hz is 9.83 seconds and the deceleration time is also 9.83

seconds. ((60-1) x 10/60=9.83secs).



When the Jog command is “ON”, the AC drive will accelerate from Minimum Output

Frequency (Pr.01-05) to Jog Frequency (Pr.01-14). When the Jog command is “OFF”,

the AC drive will decelerate from Jog Frequency to zero. The Accel/Decel time is decided

by the Jog Accel/Decel time (Pr.01-13, Pr01-22).



During operation, the AC drive cannot perform Jog command. And during Jog operation,

other operation commands cannot be accepted, except command of FORWARD,

REVERSE and STOP keys on the digital keypad.
