4.11.2 Jog operation (Pr. 15, Pr. 16)
The above parameters are displayed as simple mode parameters only when the parameter unit (FR-PU04/FR-PU07) is connected. When the
operation panel (FR-DU07) is connected, the above parameters can be set only when Pr. 160 User group read selection = "0". (Refer to page 308)
* When the setting of Pr. 21 Acceleration/deceleration time increments is "0" (initial value), the setting range is "0 to 3600s" and the setting increments are
"0.1s", and when the setting is "1", the setting range is "0 to 360s" and the setting increments are "0.01s"
(1) Jog operation from outside
⋅ When the JOG signal is ON, a start and stop can be made by the start signal (STF, STR). (The JOG signal is
assigned to the terminal JOG in the initial setting)
You can set the frequency and acceleration/deceleration time for Jog operation. Jog operation can be performed
from either the outside or PU.
Can be used for conveyor positioning, test operation, etc.

Set the acceleration/deceleration time for Jog operation. Set the 
time taken to reach the frequency (Initial value is 60Hz) set in Pr. 20 
Acceleration/deceleration reference frequency
 for acceleration/
deceleration time. 
The acceleration and deceleration time cannot be set separately.
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")
