NOTE
• The motor can also be used for applications which require the rated speed of 1800 r/min.
• The torque characteristic is when the armature winding temperature is 20°C, and the input voltage to the inverter is 200 VAC
or 400 VAC.
• Constant-speed operation cannot be performed for the speed of 150 r/min or less.
• The standard models (MM-EFS[]1M and MM-EFS[]1M4) of 11 kW capacity or higher are designed for a direct connection only.
