Start/Stop, change of rotational direction,
multi-level speed operation by external I/O,
etc.
6. Display indication
(load ratio, actual speed, etc.)
Display of load ratio
(100%)
Display of actual speed
(1500rpm)
7. Multi-level speed operation ( 8 speeds )

9-3 Operating
After turning on the power, operate the product as follows.
④ To stop running
the motor
① To start runing
the motor
② To adjust the motor
rotation speed
③ To determine the
setting of the motor
rotation speed
① Running the motor
Set the operation switch to the “RUN”, the motor to start rotating .
② Adjust the speed
When pressing the “+” button, the rotation speed accelerates by 1r/min increment and when
pressing the “-“ button, the rotation speed decelerates by 1r/min decresment.
When press and hold the“+”,”-“ button, RPM will acceleration and deceleration
by 1rpm->10rpm->100rpm.
③ Rotation Speed Confirmation and Lock
- When pressing the “S” button, the rotation speed is determined.
When the display is blinking, the rotation speed has not set.
- Can lock the operation by pressing the “S” button for more than 5 seconds in the “STAND-BY”
mode for can not change the definite rotation speed.
④ Stopping the motor
Setting the operation switch to the “STAND-BY” side causes the motor to decelerate to a stop.
Setting the operation switch again to the “RUN” side causes the motor to start rotating at the
set rotation speed.
⑤ Changing the rotation direction
Change the rotation direction of the motor (gearhead) using the rotation
direction switch. The rotation direction can be changed while operating.
With the combination type, the rotation direction of the gearhead output
shaft varies depending on the rear ratio of the gearhead.

9-4 Operating by I/O signals
The motor can be operated and stopped from the external signals.
① Setting the “External operation signal input” parameter
Set the parameter (PAr-> io.En-> on / oFF) to "on" (page 14)
"on"-External I / O enabled, "oFF"-External I / O disabled / The factory setting is "oFF".
② Run command [Run when FWD or REV input is ON]
Forward rotation when FWD (No. 2) + LCOM (No. 7)
connected / Reverse rotation when REV (No. 3) + LCOM (No. 7) connected
(Operation should be made with front control Run position, no operation at stand-by)

⑥ Driving at two or more speeds
You can operate at two or more speeds by switching to external input.
Up to 8 speeds are possible.
•Operating method
Operate the motor by selecting any of the operation data No.0 to No.7 based in a combination
of ON/OFF status of the P0, P1 and P2 inputs. The motor is operated using the rotation speed,
acceleration time, deceleration time and torque limit in the selected operation data number.
•Operation procedure (When the “external operation signal input” parameter is set to “ON”)
1. Set the operation switch to “RUN” side
2. Select the operation data number suing the P0, P1 and P2 inputs
3. When the FWD or REV input is turned ON, the motor will rotate.
4. Switch the operation data number using the P0, P1, and P2 inputs
5. When the FWD or REV input switch has been turned ON or is turned OFF, the motor will stop.
* Setting speed value is example, can be changed to needed speed.
When changing from the present speed to the new speed, the acceleration time and
deceleration time set in the next operation data number are used.

•When setting the speed increasing ratio to 1.00, the speed reduction ratio
will be effective.
•When setting a longer time in the “overload alarm detection time except
when holding a shaft” parameter, an overload status may continue.
Repeating this condition may result in shorter service life of the motor and
gearhead.
•If a load exceeding the limited duty region was applied or output shaft was
holded, the “overload alarm detection time except when holding a shaft” is
maximum 5 seconds.
