Power-on 

→

 Operation mode check

Switch power on and make sure that the operation command 

indication "EXT" is lit.

(If it is not lit, press the 

 key to choose the operation mode and 

press the 

 key to switch to external operation.)

2

Start
Turn on the start switch (STF or STR).
The operation status indication "FWD" or "REV" flickers.

3

Acceleration 

→

 Constant speed

Slowly turn the potentiometer (frequency setting potentiometer) full 

clockwise.

The frequency shown on the display increases gradually to 60.00Hz.

4

Deceleration

Slowly turn the potentiometer (frequency setting potentiometer) full 

counterclockwise.

The frequency shown on the display decreases gradually to 0.00Hz.

The motor stops running.

5

Stop

Turn off the start switch (STF or STR).

Keep the start switch (STF or STR) on to perform operation, and switch it off to stop.
1) Set Pr. 15 "jog frequency" and Pr. 16 "jog acceleration/deceleration" time.
2) Set the external operation mode.
3) Switch on the jog signal. Keep the start switch (STF or STR) on to perform 

operation.
Use any of Pr. 180 to Pr. 186 (input terminal function selection) to assign the
