Kollmorgen BDS5T-210

Kollmorgen BDS5T-210

Product Overview The BDS5T-210 is a higher-power variant within Kollmorgen’s BDS5T programmable servo drive series. It delivers substantially greater output current than the 203 model while maintaining the same intelligent motion control capabilities and torque command functionality. This drive is suited for medium-duty industrial applications requiring higher torque and faster acceleration.

Description

Kollmorgen BDS5T-210

Technical Specifications

  • Main DC Bus Voltage: 225 VDC minimum to 360 VDC maximum
  • Logic Power Supply: ±15 to 20 VDC at 0.25 A; +8 to 12 VDC at 1.00 Amp
  • Continuous Output Current: 10.0 Amps RMS at 45°C ambient, convection cooled
  • Peak Output Current: 20.0 Amps RMS for 2.0 seconds duration
  • Output Power at 160 VDC Bus: 4.0 KVA continuous; 8.0 KVA peak
  • Internal Heat Dissipation: 75 Watts maximum
  • Control Architecture: Three-loop control with position, velocity, and torque modes
  • Programming: Full motion control language identical to BDS5-203

Functional Features

  • All programming features of the BDS5 series including multitasking, S-curves, and electronic gearbox
  • Higher current capacity for larger frame servo motors
  • Enhanced internal heatsink design for 75W dissipation
  • Compatible with Kollmorgen GOLDLine series brushless motors
  • External regeneration resistor capability for high-deceleration applications
  • Resolver and encoder feedback interfaces
  • General purpose I/O for machine integration

Application Scenarios

  • Medium-duty CNC machinery axis control
  • Industrial robots and articulated arms
  • Large format printing and scanning systems
  • Metal forming and stamping equipment
  • High-speed packaging lines
  • Automated guided vehicle steering systems

Performance Parameters

  • 10 Amp continuous current supports motors up to approximately 2 kW mechanical output
  • 20 Amp peak current delivers 3:1 overload capability for acceleration
  • 4 KVA continuous output power at nominal bus voltage
  • Maintains full programming capability at maximum current output

Structural Characteristics

  • Larger chassis footprint than BDS5-203 to accommodate higher power components
  • Enhanced aluminum heatsink with greater surface area
  • Heavy-duty power terminals rated for 20 Amp peak current
  • Same control interface layout as smaller BDS5 variants for consistency

Working Principle Identical control architecture to BDS5-203 but with scaled power stage. The PWM output stage uses higher current-rated IGBT or MOSFET power switches to deliver 10 Amps continuous. The control processor executes the same motion programs, but the current loop compensator is tuned for the higher power bandwidth. Torque mode operation provides direct current command proportional to input signal, suitable for tension control and force applications.

Installation Requirements

  • Require larger electrical enclosure due to increased heat dissipation
  • Use 14 AWG or larger wire for motor power connections
  • External regeneration resistor strongly recommended given 75W internal dissipation
  • Ensure 8-inch minimum clearance around heatsink surfaces

Operating Precautions

  • Higher peak currents demand careful motor thermal verification
  • Monitor drive chassis temperature during extended operation
  • Verify external regen resistor wattage rating matches application duty cycle
  • Do not operate at peak current beyond 2-second rating to prevent thermal shutdown
