Kollmorgen PRD-KD40EAIZ-62
Product Name: SERVOSTAR CD Series Drive System Code (KD40 Power Stage, EAIZ Option String, 62 Revision)
Introduction: PRD-prefixed assembly code from the CD/ServoStar CD era. “KD40” indicates approx. 40 A or 4 kVA class power module; “EAIZ” encodes supply/feedback/option set; “-62” is internal revision. Effectively a panel-mount CD drive for brushless motors.
Detailed content
Technical Specifications (typical CD KD40 class):
-
Supply: 3-phase 230–480 VAC depending on variant
-
Continuous current: approx. 12–18 A (KD40 is mid-range, not 40 A literal)
-
Control: torque/velocity/position
-
Feedback: resolver, encoder, optional SSI
-
Protection: IP20 (some CD variants IP67 depending on housing option)
-
Mount: panel inside cabinetFunctional Features: Analog/digital hybrid command, auto-commutation, motor database commissioning, replaces older B-series analog amps.Structure & Materials: Sheet metal case, Eurocard power board, isolated I/O.Working Principle: Same AC-DC-AC servo topology with resolver-based commutation.Installation Requirements: Verify actual nameplate—PRD code alone does not fix voltage or current; match to existing CD rack or standalone mount.Precautions: PRD-KD40EAIZ-62 is an order/build code, not a catalog headline; confirm voltage jumpers and feedback card before energizing; incompatible directly with AKD single-cable motors unless adapter used.
