Product Name: BDS5A-103-0101 PWM Digital Servo Drive (Brushless DC / AC Servo Amplifier)
-
Product Introduction: Kollmorgen BDS5 family digital servo amplifier — full-digital DSP-based drive for 1- or 3-phase brushless servo motors (Goldline B/M/BH/MH etc.). Provides torque, velocity, and position control modes; accepts ±10 V analog command, step/direction, or master-follower.

-
Input Power: 115/230 VAC single- or 3-phase (verify label)
-
Bus Voltage Range: ~160–325 VDC internally regulated
-
Control Modes: Torque (current), Velocity (with tach feedback or estimator), Position (with encoder/resolver)
-
Feedback Supported: Resolver, Incremental Encoder, optional SinCos
-
I/O: ±10 V analog command, Enable, Fault, Ready contacts, ±15 V reference
-
Commutation: Software-selectable — auto-commutate with resolver or encoder index
-
Protections: Over-current, over-voltage, under-voltage, over-temperature, following error
-
Mounting: Panel mount with heat sink; forced air cooling recommended above 10 A
-
-
Features: Auto-tuning capability, programmable gain sets, electronic gearing, dual-command source selectable.
-
Installation & Notes:
-
Requires proper motor-to-drive parameter matching (motor Kt, Ke, pole count, resolver transformation ratio).
-
Regenerative resistor may be needed for frequent deceleration of large inertial loads.
-
Observe grounding and shielding practices — BDS5 is sensitive to noise on feedback lines.
