Operating method
Operate the motor by selecting any of the operation data No.0 to No.3 based on a combination of ON/OFF status of
the M0 and M1 inputs. The motor is operated using the rotation speed, acceleration time, and deceleration time in the
selected operation data number. This explains an example for when 4-speed operation is performed with the FWD, M0,
and M1 inputs.
[Operation procedure]
1. Set the "external operation signal input" parameter to "ON" from "OFF." (Factory setting: OFF)
2. Set the operation switch to the "RUN" side.
3. Select the operation data number using the M0 and M1 inputs.
4. When the FWD input is turned ON, the motor rotates at the rotation speed of the selected
operation data number.
5. If the M0 and M1 inputs are switched, the motor changes to the rotation speed of the operation
data number selected.
6. If the FWD input being ON is turned OFF, the motor decelerates to a stop.
