Jogging Command
When the terminal [JG] is turned on and the
Run command is issued, the inverter outputs
the programmed jog frequency to the motor.
Use a switch between terminals [JG] and
[P24] to activate the JG frequency.
The frequency for the jogging operation is set
by parameter A38.
Set the value 01(terminal mode) in A02 (Run
command). Since jogging does not use an
acceleration ramp, we recommend setting the jogging frequency in A38 to 5 Hz or less
to prevent tripping.
The type of deceleration used to end a motor jog is selectable by programming function
A39. The options are:
• 00 Free-run stop (coasting)
• 01 Deceleration (normal level) and stop
• 02 Use DC braking and stop
