GE A208-0004-0170/10D Servo Drive

The GE A208-0004-0170/10D, also cataloged as the A208-0004-0170 Servo Drive, operates as a dedicated hardware component for closed-loop motor vector control and regenerative energy management within CNC motion control systems.

Hardware Specifications

V/Hz and Field-Oriented Vector Control Execution

The A208-0004-0170/10D utilizes six onboard IGBT modules driven by three-phase Hall effect feedback sensors to execute high-bandwidth field-oriented vector control algorithms. The internal power stage dynamically balances thermal heat sink dissipation profiles while maintaining precise current loop modulation. A 2400 uF DC link capacitance coupled with an integrated braking chopper absorbs regenerative voltage surges during steep deceleration ramps to preserve drive stability.

Frequently Asked Questions

Q: Does this servo drive retain parameter configurations internally during main power shutdown?

A: No. The drive does not contain a battery backup circuit for non-volatile storage. All drive parameters and motor profiles must be saved externally and reloaded via controller software if power is cycled.

Q: What mounting orientation is required to ensure adequate thermal heat dissipation?

A: The unit must be mounted vertically on a flat surface to facilitate unimpeded natural thermal convection across the rear heat sink assembly.

Field Installation Guidelines

1. Isolate primary 230 VAC three-phase supply voltage and lock out main disconnects prior to touching electrical terminals.
2. Mount the chassis vertically, maintaining a minimum clearance of 100 mm above and below the heat sink assembly for convection cooling.
3. Terminate motor phase leads and external braking resistor lines using shielded cables grounded at a single chassis grounding stud.
4. Route the +/-10 VDC analog command and resolver feedback lines separately from three-phase power conductors to prevent electrical noise coupling.
