Kollmorgen 60WKS-M240/26
-
Product Name: Seidel 60WKS Analog Brushless Servo Amplifier
-
Product Introduction: Industrial analog servo drive from Seidel (absorbed into Kollmorgen), built for 240 VAC-class 3-phase input and ±10 V speed/torque command control of brushless synchronous servo motors.
Detailed content
-
Technical Specifications:
-
Input Supply: 3 × 240 VAC (wide range 100–240 VAC variants exist, M240 denotes 240 V motor class)
-
DC Bus: approx. 320 VDC
-
Continuous Output Current: 13 A
-
Peak Output Current: 26 A
-
Control: analog differential ±10 V, resolver or tachometer feedback
-
Construction: 19-inch rack module or compact housing variant
-
Protection: IP20, cabinet-only installation
-
Compliance: EMC 89/336/EEC, Low Voltage 73/23/EEC, EN 60204
-
-
Functional Features: High dynamic IGBT/transistor output stage; adjustable gain and tach filter; fault relay; overcurrent/overvoltage/short-circuit monitoring; operates from isolating transformer or Seidel DC supply.
-
Material / Structure: Folded sheet-metal case; finned heat sink; PCB with analog command section and power bridge; rear backplane edge connector.
-
Working Principle: Mains isolated to DC bus, PWM commutated 3-phase current based on rotor angle from resolver/tacho, analog input sets speed or torque setpoint.
-
Application Scenarios: Legacy CNC axes, robot joints, converting lines, press feeds using Seidel SM-series or Kollmorgen 6SM motors.
-
Installation Requirements: Install in grounded steel enclosure with forced airflow if stacked; supply via isolating transformer per Seidel spec; separate signal and power shields; fuse primary per manual.
-
Usage Notes: Obsolete series, treat as spare-only; M240/26 means 240 V motor class, 13 A cont / 26 A peak; analog loop gains must be re-tuned when motor inertia changes; disable output before disconnecting motor under power.
