Kollmorgen E33NCHA-LNN-NS-00 Wiring Steps

1. Pre-Wiring Preparation

Confirm the matched servo drive is fully compatible with the E33NCHA-LNN-NS-00 servo motor (230 VAC operating voltage, 3.3 A RMS continuous current). Completely cut off the servo drive main power and control power, and wait for full discharge of internal bus capacitors to ensure operation safety. Prepare dedicated shielded motor power cables and absolute encoder feedback cables. Inspect motor power connectors and feedback connectors for shell damage, pin deformation and poor contact. Complete motor mechanical installation and coupling alignment before wiring construction. Confirm the cabinet protective grounding bar is intact and available for use.

2. Cable Routing and EMC Layout

Strictly separate high-power motor cables and low-signal encoder cables, avoid long-distance parallel laying, and keep a minimum spacing of 20 cm to reduce electromagnetic interference. Arrange cables in cable chains for moving equipment scenarios. Avoid excessive bending, twisting and stretching of cables and connectors. Reserve reasonable cable slack to adapt to motor stroke and mechanical movement, preventing cable tension damage during operation.

3. Motor Power Wiring

Connect the three-phase power terminals U, V, W of the motor and servo drive output strictly in corresponding phase sequence to ensure consistent phase order. Use green-yellow grounding wire to connect the motor power cable PE terminal to the cabinet protective grounding bar. Terminate and ground the power cable shielding layer at the drive side. Fasten the M23 power connector with standard torque to ensure intact IP65 waterproof and dustproof performance. This motor model has no built-in holding brake, so no brake wiring is required.

4. Absolute Encoder Feedback Wiring

Lay dedicated shielded feedback cables to connect the motor encoder port and servo drive feedback interface. The drive provides 24 VDC power supply (allowable range: 20–28 VDC) for the encoder, with accurate matching of 0 V reference signal wiring. Standardize the termination of absolute serial position signal lines. Adopt single-point grounding for feedback cables: only ground the shielding layer at the drive side, and keep the motor-side shielding floating. Fasten encoder connector locking screws with specified torque to prevent loose contact and signal interruption during long-term operation.

5. System Grounding Configuration

Use short-distance and large-section copper wires to connect the motor housing to the cabinet protective grounding bar. Do not rely solely on connector shielding for system grounding. Realize equipotential grounding of the servo drive chassis, equipment cabinet and motor housing to effectively suppress interference and ensure operational safety.

6. Post-Wiring Visual Inspection

Recheck the U/V/W three-phase phase sequence again to eliminate phase-to-phase short circuit and phase-to-ground short circuit risks. Verify the encoder power supply matches the standard voltage range with no signal line short circuit or open circuit. Confirm all connectors are fully locked and fastened, with complete sealing rings and cable glands to meet IP protection requirements. Ensure no bare wires or exposed conductors are present.

7. Insulation and Continuity Test

Perform all tests under full power-off state. Measure the insulation resistance between motor U/V/W windings and PE grounding terminal to confirm no insulation aging or breakdown. Test the continuity of the whole grounding loop to ensure reliable grounding performance.

8. Power-On Pre-Inspection

Switch on the servo drive control power only, keep the drive in disabled state. Establish communication with the drive via Kollmorgen WorkBench software. Verify the system correctly identifies the motor absolute encoder, normally reads motor position data, and confirms no feedback faults or alarm codes.

9. No-Load Commissioning Test

Disconnect the motor mechanical coupling to ensure no load on the motor shaft. Enable the servo drive and complete motor parameter auto-identification. Perform inching jog test to check motor rotation direction; swap any two of the U/V/W phases if the rotation direction is reversed. Monitor real-time operating current, motor temperature and encoder status to ensure no over-current, abnormal vibration or system alarms.

10. Final Verification and Handover

Power off the system again, re-tighten all connectors as required. Restore the motor mechanical coupling connection. Save and back up all servo drive configuration parameters. Complete wiring inspection records and test logs, and put the motor into formal normal operating state.
