Kollmorgen PRD‑AMPB25EZ‑00REV

Product Introduction: Revised hardware‑revision variant of PRD‑AMPB25EZ‑00 analog servo amplifier. Internal component layout and protection‑circuit parameters are optimized. It maintains identical external pin‑out, mechanical dimension and core performance parameters. It executes analog torque‑velocity closed‑loop control for brushless permanent‑magnet servo motors, supports four‑quadrant regenerative operation. Used as direct drop‑in replacement unit for original PRD‑AMPB25EZ‑00 amplifier in legacy equipment maintenance scenarios.

Description

Kollmorgen PRD‑AMPB25EZ‑00REV

Technical Specifications: Single‑phase 115‑230 VAC input, 50‑60 Hz; continuous output current 25 Arms; peak output current 50 Arms; switching frequency 20 kHz; ±10 V analog command interface; resolver and incremental encoder feedback support; optically‑isolated digital enable input; fault‑relay contact output; external regeneration‑resistor terminal; operating temperature 0‑50 °C; storage temperature‑20‑85 °C; humidity 5‑95 % RH non‑condensing; panel‑mount chassis structure; weight 3.4 kg.

Functional Features: Four‑quadrant regenerative power operation; optimized hardware current‑limiting protection; analog PI‑loop gain adjustment via potentiometers; resolver‑based motor commutation; fault‑relay alarm‑contact output; external regeneration‑resistor connection; analog monitor test‑points for real‑time signal observation; hardware inhibit input for emergency‑stop function; revised internal over‑temperature protection threshold for improved reliability.

Application Scenarios: Replacement for PRD‑AMPB25EZ‑00 in vintage heavy‑duty CNC machine‑tools, large‑format printing machinery, material‑handling automation equipment, old‑style automated production‑line maintenance work.

Performance Parameters: Current‑loop bandwidth up to 1000 Hz; velocity‑loop bandwidth adjustable up to 400 Hz; short‑term 200 % peak overload capacity for 30 seconds; optimized hardware fault‑detection response speed.

Material Composition: Revised‑version die‑cast aluminum alloy housing; high‑power IGBT power modules; gold‑plated industrial locking connectors; revised‑layout flame‑retardant high‑voltage PCB circuit board; metal heat‑sink fin assembly; front‑panel adjustment potentiometers and LED indicator array; metal mounting brackets.

Structural Features: Identical mechanical dimension and panel‑mount structure as PRD‑AMPB25EZ‑00; front‑panel fitted with adjustment potentiometers and status LED indicators; rear‑side pin‑out and connector definition fully compatible with original unit; non‑fan convection‑cooling structure; all external signal ports adopt industrial‑grade locking connectors.

Working Principle: AC input power is rectified into DC‑bus voltage. Power semiconductor devices output three‑phase variable‑frequency current to drive brushless servo motor. Resolver or encoder feedback delivers rotor position and velocity signals into analog PI‑control circuits. Amplifier responds to ±10 V external analog command to realize torque and velocity closed‑loop regulation. Revised‑version hardware monitoring circuits continuously sample current, temperature and bus voltage with optimized threshold parameters. Fault conditions trigger immediate power‑stage shutdown and activate fault‑relay output.

Installation Requirements: Install vertically inside industrial control cabinet; maintain 80 mm upper‑lower ventilation clearance and 50 mm left‑right clearance; separate power cables and signal cables with physical distance greater than 12 cm; all shielded signal cables implement single‑end shield grounding; connect unit protective‑earth terminal to cabinet grounding‑bar reliably; install external regeneration‑resistor according to actual deceleration‑energy demand.

Usage Notes: Allow sufficient DC‑bus bleeding‑off time before opening cabinet for maintenance; strictly prohibit live‑plugging motor and feedback connectors; do not exceed rated input voltage and output‑current parameters; regularly inspect fault‑relay contact status and terminal‑tightening condition; direct drop‑in replacement for PRD‑AMPB25EZ‑00 without mechanical modification; verify fault‑relay logic after replacement installation.
