Jog Frequency - Delta Electronics AC Motor Drive VFD-EL User Manual

Chapter 4 Parameters|
In the diagram shown below, the Acceleration/Deceleration Time of the AC motor drive is the
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 motor drive to
accelerate from start-up to 60 Hz and to decelerate from 60Hz to 1.0Hz is in this case 9.83
seconds. ((60-1) * 10/60=9.83secs).

Only external terminal JOG (MI3 to MI12) can be used. When the Jog command is "ON", the
AC motor drive will accelerate from Minimum Output Frequency (Pr.01.05) to Jog Frequency
(Pr.01.15). When the Jog command is "OFF", the AC motor drive will decelerate from Jog
Frequency to zero. The used Accel/Decel time is set by the Jog Accel/Decel time (Pr.01.13,
Pr.01.14).
