1.11 Motor specification
(1) Specifications
*1 When the power supply voltage drops, we cannot guarantee the above output and rated speed.
*2 When the load torque is 20% of the motor rating. The permissible load inertia moment ratio is smaller when the load torque is larger.
Consult us if the load inertia moment ratio exceeds the above value.
*3 This does not apply to the shaft through portion.
*4 Value for MM-CF2C.
*5 The value for MM-CF2B is indicated in parentheses.
*6 Applicable one-rank higher inverters for the lifted low-speed range torque operation.
Motor 2000r/min Series
