2.4.2 When Jog operation [Pr. 15, 16]
(common)
You can set the frequency and acceleration/deceleration
time for Jog operation. Jog operation can be performed
from either of the External or the PU operation mode.
This operation can be used for conveyor positioning, test
operation, etc. During Jog operation, the second acceleration/deceleration
via RT signal cannot be selected. (The other second
functions are valid)
This function is invalid when [
Pr. 79 = "3"].
Jog operation is invalid under position control. For ,
Jog operation is invalid with the position control of vector
control.

*
Set the acceleration/deceleration time for Jog operation. As the acceleration/
deceleration time, set the time taken to reach the frequency (initial value is 60Hz) set in
[
Pr. 20 Acceleration/deceleration reference frequency ].
Acceleration/deceleration time can not be set separately.
When [
Pr. 29 Acceleration/deceleration pattern selection = "1"], the acceleration/
deceleration time of S-pattern acceleration/deceleration A is the time required to reach
[
Pr. 3 Rated motor frequency ].
* 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".
[ Pr. 21 ] is not available for . Setting range of [ Pr. 16 ] is 0 to 3600s, and the increment is 0.1s.

(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.)
(2) Jog operation from PU
Press to choose the Jog operation mode.
Hold down the (or ) key to perform
operation.
When [
Pr. 79 Operation mode selection = "4"],
pressing / of the parameter unit starts
the inverter and pressing stops the inverter.
