1. Running the motor
Set the operation switch to the “RUN”, the motor to start rotating.
2. Adjust the speed
Pressing the button, the speed increase by 1 r/min,
Pressing the button, the speed decrease by 1 r/min.
3. Determining the speed
- Set
Pressing the button, the rotation speed is determined.
When the display is blinking, the rotation speed has not set.

- Confirmation
Prevents the undesired changes in the speed,
Press the button for 5 seconds or more when STAND-BY mode when “LOCK” appears, the lock function is activated.
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.

Operation by I/O Signals

1. Operation Method
- Using the built-in power supply in the driver, the motor is operated through external signals.
- Connect Pins the I/O signal connector as in the figure of the righ.
- When operating using external signals, change the parameter setting in the “external operation signal input” to “on”. Refer to Manual.
- Using the external I/O signals, the motor can be operated 8-Speeds data.

3. Timing Chart
In case of parameter “external operation signal input” to “on” and the rotation direction switch is set to “FWD”.
· The motor rotates when either FWD input or REV input is set to “ON”.
· The motor instantaneous stop when FWD input and REV input is set to “ON” at the same time.
4. Example of connection using Switches or Relays
This is an example of connection when operating Ezi-SPEED using contact switches such as switches or relays.
5. Connection example for I/O signals and programmable controller
This is connection example when the motor is operated using a transistor output type programmable controller.
  • ※ For the Y0, Y1 and Y2, be sure to keep the current value at 100mA or less,
       If the current exceeds this value, connect the limiting resistor R.

6. In the case of using a external controller with a built-in clamp diode
If a external controller with a built-in clamp diode is used, a leakage path may form and cause the motor to operate even when the external controller power is off, as long as the drive power is on. Since the power capacity of the controller is different from that of the drive, the motor may operate when the external controller and drive powers ate turned on or off simultaneously. When powering down, turn off the drive power first, followed by the external controller power. When powering up, turn off the external controller power first, followed by the drive power.
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.
7. 8-Speed Operation(In the case of the “external operation signal input” parameter is set to “ON”)
① Set the operation switch to the “RUN” side.
② Select the operation data number using the P0, P1 and P2 inputs.
③ When either of the FWD input 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 input or REV input which has been turned ON is turned OFF, the motor will stop.

5 ON OFF ON 2,500
6 OFF ON ON 4,000
