Jog Operation (Pr. 15, Pr. 16) - Mitsubishi Electric FR-E720-008 Instruction Manual

4.7.2

Jog operation (Pr. 15, Pr. 16)

You can set the frequency and acceleration/deceleration time for Jog operation. 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.

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 when Pr. 160 User group read selection = "0". (Refer to page 187)
∗ When the Pr. 21 Acceleration/deceleration time increments setting is "0" (initial value), the setting range is "0 to 3600s" and setting increments is "0.1s". When
the setting is "1", the setting range is "0 to 360s" and the setting increments is "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).
For the terminal used for Jog operation selection, set "5" in any of Pr.178 to Pr.184 (input terminal function selection) to assign
the function.

Operation
1.
Screen at powering ON
Confirm that the External operation mode is
selected. ([EXT] lit)
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 ON the JOG switch.
3.
Turn the start switch (STF or STR) ON.
The motor runs while the start switch (STF
or STR) is ON.
The motor runs 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")
The acceleration time and deceleration time cannot be set separately for Jog operation.
