Working Principle The drive operates by receiving command inputs through serial communication or internal program execution. The processor calculates motion profiles and generates current commands for the three-phase PWM output stage. Motor position feedback from resolver or encoder is compared against commanded position to generate error signals. The control algorithm processes position, velocity, and current loops sequentially to produce smooth, accurate motion. In torque mode, the velocity feedback loop is bypassed and current command is derived directly from the torque command input multiplied by the proportional gain constant.
Installation Requirements
- Install in NEMA-rated electrical enclosure with minimum IP54 protection
- Maintain 6-inch clearance around heatsink for natural convection
- Connect external regeneration resistor kit if duty cycle exceeds internal dissipation capacity
- Use Kollmorgen PSR4/5 connector kits for proper motor and feedback cable termination
- Configure autobaud communication before applying motor power
Operating Precautions
- Only qualified personnel should install, set up, and operate this equipment
- Ensure all system components including motor and drive are properly grounded
- Verify DC bus polarity before connection as reverse polarity causes permanent damage
- Do not operate without proper motor feedback connected
- Monitor internal temperature during extended peak current operation
- Back up all motion programs before firmware updates
