Features

Benefits

Current Limit

Spindle motor can accelerate up in current limit thus providing the fastest acceleration rate possible.

Built-in Dynamic Braking Transistor for commonly used Drive sizes in the Machine Tool Industry
 

Reduced costs when applying Dynamic Braking in order to achieve fast deceleration

Overtorque Detection

The drive can warn the user of a damaging load related fault situation before it occurs by using Overtorque and/or Undertorque Detection.

This is useful to detect any wear or damage along the cutting blades or bits.

BCD/Binary Digital Input (DI-08, 16 options)

· I/O Interface with numerical controls (NC)

· Multi-function Inputs and Outputs

· Speed Agree Output

Energy Saving Mode 
(reduces the amount of excitation current that arises with lighter loads)

Suppress any vibration or instability that occurs when performing light machining for the finishing of the work piece.

Zero-Servo and Orientation Function

Stop at a fixed location

Maximum Frequency
