Jog Operation (Pr. 15, Pr. 16) - Mitsubishi Electric FR-A720-0.4K Instruction Manual

4.11.2 Jog operation (Pr. 15, Pr. 16)

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.

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 293)
* 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)

If not displayed, press
external [EXT] operation mode.
If the operation mode still does not change,
set Pr. 79 to change to the external operation mode.
2.
Turn the JOG switch on.
3.
Turn the start switch (STF or STR) on.
The motor rotates while start switch
(STF or STR) is ON.
Rotates at 5Hz. (Initial value of Pr. 15)
4.
Turn the start switch (STF or STR) off.
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")

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