REMARKS
· The motor can also be used for applications which require the rated speed of 1800r/min.
CAUTION
• The torque characteristic is when the armature winding temperature is 20°C, and the input voltage to the inverter is
400VAC.
• Constant-speed operation cannot be performed for the speed of 150r/min or less.
