• PWM mode I!ID
By changing PWM mode setting, it is possible to select motor sound
appropriate for load and to reduce resonant vibration for the standard acoustic
noise model. Available in sixteen settings.
• Electronicthermal relay
rn
The setting value can be set as a current value (A) for the motor's overheating
protection. Optimum protection characteristics. including a drop in the motor
cooling performance at low speed operation. can be obtained. The motor
protection function will not operate when set to 0 (A). (The output transistor
protection function will operate.)
Set the motor rating current at 50Hz for a triple-rating motor.
Set to 0 (A) when using the external thermal relay.
