Digital Input Sinusoidal Brushless Servo Amplifiers

The DigiFlex® Performance™ (DP) Series digital servo drives are designed to drive brushed and brushless servomotors. These fully digital drives operate in torque, velocity, or position mode and employ Space Vector Modulation (SVM), which results in higher bus voltage utilization and reduced heat dissipation compared to traditional PWM. The drive can be configured for a variety of external command signals. Commands can also be configured using the drive’s built-in Motion Engine, an internal motion controller used with distributed motion applications. In addition to motor control, these drives feature dedicated and programmable digital and analog inputs and outputs to enhance interfacing with external controllers and devices.

This DP Series drive features a single RS-232/RS-485 interface used for drive configuration and setup. Drive commissioning is accomplished using DriveWare® 7, available for download at www.a-m-c.com.

All drive and motor parameters are stored in non-volatile memory.

These drives support resolver feedback. Resolvers are very reliable in hostile industrial environments, as they are resilient to vibration, dirt and high temperatures.

Resolver Requirements: 5kHz carrier frequency / 4Vrms excitation voltage / 0.5 transformation ratio / 12 or 14-bit user configurable interpolation

DPR-series drives now support Indexing and Jogging commands using the Motion Engine feature in DriveWare^® 7.

The combination of a DigiFlex® Performance™ servo drive with the DriveWare software establishes a new benchmark in versatility! Capabilities built into DigiFlex® servo drives include:

• Full tuning control of all three servo loops: Position, Velocity and Torque
• Real-time oscilloscope with up to 8 channels to ensure that tuning achieves the highest performance
• Status window with over 50 simultaneous channels for drive and system diagnostics
• I/O configuration for over 60 events and signals, configurable to latch/non-latch as well as active-high and active-low
• Universal servo motor compatibility by means of automatic commutation adjustment
• Dual Loop Feedback - Increases both stability and accuracy.
