The JOG function can be selected using Multi-function Input terminals (Pr.4-04 to Pr.4-08) if
programmed for Jog (d10). When the Jog terminal is “closed”, the AC drive will accelerate
from Minimum Output Frequency (Pr.1-05) to Jog Frequency (Pr.1-14). When the Jog
terminal “open”, the AC drive will decelerate from Jog Frequency to zero. The
acceleration/deceleration time is decided by the Jog acceleration/deceleration time (Pr.1-13).
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.
