Frequently Asked Questions

What is the difference between ND and HD ratings?
ND (Normal Duty) is for standard applications. HD (Heavy Duty) is for applications with high starting torque or frequent starts/stops. Choose the rating based on your motor's hardest job.

Can this drive run on a standard 460V supply?
Yes. A 460V supply is within the 480V AC input range. The drive will operate normally.

What does "110% overload for 60 seconds" mean?
The drive can safely deliver 10% more than its rated current for one minute. This handles temporary high-demand situations without faulting.

Is a programming keypad included?
No. This is an open-type drive without a Human Interface Module (HIM). You may need to purchase one separately for initial setup.

How does the internal brake transistor help?
It provides dynamic braking, helping to stop the motor faster than just coasting. This is useful for applications that need precise stopping control.
