Frequently Asked Questions

What does ND and HD mean for this drive?
ND is Normal Duty for standard applications. HD is Heavy Duty for tougher uses with higher torque demands. Always check the current rating for your voltage.

Can I use it on a 415V system?
Yes. A 415V system falls within the 400V class input range (342-440V AC). It will operate correctly.

Is a keypad included for programming?
No, this open-type drive does not come with a Human Interface Module (HIM). You may need to purchase one separately for parameter setup.

What is the purpose of the internal brake transistor?
It helps to quickly stop the motor by dissipating excess energy, which is useful for applications requiring fast stopping or holding a load.

How do I choose between 400V and 480V operation?
The drive auto-detects the input voltage. You must set the motor parameters (like voltage and current) correctly for your specific motor and supply voltage.
