Kollmorgen BDS5A-220-0001
Product Name: BDS5 Series Servo Amplifier/Drive
Product Introduction: The BDS5 is a legacy digital servo drive series from Kollmorgen, designed for demanding motion control. The “220” likely refers to voltage/current rating (e.g., 220V class or 20A range), and “A” denotes specific hardware revision or option.
Detailed content
Technical Specifications:
-
Output Voltage: 90-160 VAC L-L (depending on exact BDS5 variant, some are 230V class)
-
Continuous Current: Varies by model (e.g., BDS5-106 is 6A, BDS5-120 is 20A); “220” suggests mid-range current.
-
PWM Frequency: 10 kHz typical
-
Logic Supply: +15-20VDC @ 0.25A, +8-12VDC @ 1.0A
-
Resolver Excitation: 8.5 kHzFunctional Features: Supports resolver feedback primarily; analog input control (+/-10V); programmable gain and compensation; fault outputs for diagnostics.Application Scenarios: Retrofit applications, older machine tools, custom automation where resolver-based motors are used.Material Composition: Heavy-gauge steel chassis, through-hole PCB technology, large electrolytic bus capacitors.Structural Features: Larger form factor than S-series; screw terminal blocks for power; DB-style connectors for feedback/I/O; convection or fan-cooled depending on current.Working Principle: Analog/Digital hybrid or full digital control loop generating PWM to regulate motor current based on resolver position feedback and command input.Installation Requirements: Requires shielded cable for motor and feedback; separate grounding for logic and power; regen resistor may be needed externally.Usage Precautions: This is an older generation drive; spare parts may be limited. Ensure compatibility with modern 24V logic levels (some units use 12V logic). Watch for “Feedback Loss” (Error 17) if resolver cables are unshielded.
