Description

Kollmorgen PRD‑AMPB25EZ‑00

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; 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.

Application Scenarios: Vintage heavy‑duty CNC machine‑tool axes, large‑format printing machinery, material‑handling automation equipment, retrofitting and spare‑part replacement for old‑style automated production‑lines.

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; fast hardware fault detection and latch‑up.

Material Composition: Die‑cast aluminum alloy housing; high‑power IGBT power modules; gold‑plated industrial locking connectors; 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: Heavy‑duty panel‑mount metal chassis; front‑panel fitted with adjustment potentiometers and status LED indicators; rear section equipped with power terminals, motor connector, feedback connector and analog‑signal terminals; 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. Hardware monitoring circuits continuously sample current, temperature and bus voltage. 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; replacement spare‑parts must match hardware revision and motor‑feedback type.
