The above characteristics apply when the rated AC voltage is input from the inverter. (Refer to page 150.) Output and rated motor speed are
not guaranteed when the power supply voltage drops.
*2
This excludes the part where the axis passes through.
Motor torque characteristic
The following figures show the torque characteristics of high-efficiency IPM motors [MM-EF (1800r/min) series]
when used with inverters.

CAUTION
• The torque characteristic is when the armature winding temperature is 20°C, and the input voltage to the inverter is 200VAC
or 400VAC.
• Constant-speed operation cannot be performed for the speed of 180r/min or less.
