The Jog input [JG] is used to command the 
motor to rotate slowly in small increments for 
manual operation. The speed is limited to 
10 Hz. The frequency for the jogging opera-
tion is set by parameter A038. Jogging does 
not use an acceleration ramp, so we recom-
mend setting the jogging frequency A038 to 
5 Hz or less to prevent tripping.

When the terminal [JG] is turned ON and the 
Run command is issued, the inverter outputs 
the programmed jog frequency to the motor. 
To enable the Run key on the digital operator 
for jog input, set the value 01(terminal mode) 
in A002 (Run command source).

The type of deceleration used to end a motor jog operation is selectable by programming 
function A039. The options are:

• 00   Free-run stop (coasting)

• 01   Deceleration (normal level) and stop

• 02   Use DC braking and stop

A002= 01, A038 > B082,
A038 > 0, A039

No jogging operation is performed when the set 
value of jogging frequency A038 is smaller than the 
start frequency B082, or the

 value is 0 Hz.

Be sure to stop the motor when switching the 
function [JG] ON or OFF.
