Frequency setting by external terminals
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 299)
* 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.

Pr. 20
Acceleration/deceleration reference frequency for acceleration/
deceleration time.
The acceleration and deceleration time cannot be set separately.
REMARKS
