-
Integrated position controller with program memory
-
Electronic gearing and registration functions
-
STO-capable variants in later firmware
-
Auto-tuning through Windows GUI
Application Scenarios:
-
Retrofit of older Kollmorgen Goldline / 6SM motors
-
Standalone single-axis machines
-
Converting, labeling, light CNC
Working Principle:
AC mains is rectified to a DC bus; an IGBT bridge synthesizes 3-phase PWM current to the motor under closed-loop control from rotor feedback. Command source can be analog ±10 V, pulse/direction, master encoder, or internal motion program.
Installation Requirements:
-
Vertical mounting on grounded metal panel
-
Top/bottom clearance ≥ 40 mm, side clearance ≥ 75 mm
-
24 V DC control supply isolated from power ground
-
Shielded feedback and motor cables, separated from power runs
Usage Precautions:
-
Not for new designs; use AKD or Essentials for spare planning
-
Verify firmware vs. motor feedback type before power-up
-
Regenerative resistor may be required for high-inertia decel
