7.5.1 Motor specification

The above characteristics apply when the rated AC voltage is input from the inverter. (Refer to page 330)
Output and rated motor speed are not guaranteed when the power supply voltage drops.

This excludes the part where the axis passes through.


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.
