Others
The available power supply input is three-phase 200 to 240V only.
Only the electronic thermal O/L relay is provided as the temperature protective function. (Servo motor: Electronic thermal
O/L relay and encoder thermistor, MM-GKR: Electronic thermal O/L relay)
In the low-speed range (750r/min or lower for the 0.1kW, 300r/min or lower 0.2 to 0.75kW), high-frequency tone is heard
because of the high frequency superposition control.
The maximum wiring length between the drive unit and motor is 30m.
