Jog operation (Pr. 15, Pr. 16)
(1) Jog operation from outside
When the JOG signal is on, a start and stop can be made by the start signal (STF, STR).
For the terminal used for Jog operation selection, set "5" in any of Pr.178 to Pr.182 (input terminal function selection) to assign
For the terminal used for Jog operation selection, set "5" in any of Pr.178 to Pr.182 (input terminal function selection) to assign
the function.
The frequency and acceleration/deceleration time for Jog operation can be set. Jog operation can be performed in either
of the external and the PU operation mode.
This operation can be used for conveyor positioning, test operation, etc.

Acceleration/deceleration time for Jog operation. Acceleration/
deceleration time is the time taken to reach the frequency set in Pr. 20
Acceleration/deceleration reference frequency (initial value is 60Hz).
Acceleration/deceleration time can not be set separately.

These parameters are displayed as simple mode parameter only when the parameter unit (FR-PU04/FR-PU07) is connected. When the parameter unit is not
connected, the above parameters can be set by setting Pr. 160 Extended function display selection = "0". (Refer to page 162)

REMARKS
When you want to change the running frequency, change Pr. 15 Jog frequency. (initial value "5Hz")
When you want to change the acceleration/deceleration time, change Pr. 16 Jog acceleration/deceleration time. (initial value "0.5s")
The acceleration time and deceleration time cannot be set separately for Jog operation.
When you want to change the acceleration/deceleration time, change Pr. 16 Jog acceleration/deceleration time. (initial value "0.5s")
The acceleration time and deceleration time cannot be set separately for Jog operation.
