Power Input (DC Bus Supply)

This servo drive relies on a shared DC bus power supply system matched with HMV series rectifier modules. The permissible DC bus operating voltage ranges from 530 VDC to 670 VDC to accommodate voltage fluctuations under variable load conditions. The control circuit adopts a nominal 26 VDC auxiliary power supply to sustain stable operation of internal logic, signal processing and communication circuits. The maximum DC bus input current reaches 37 A under full-load working conditions.

Motor Output

At a switching frequency of 4 kHz, the drive provides a continuous rated output current of 40 A for long-duration stable motor operation. It can deliver peak output current up to 75 A to satisfy short-time acceleration and high-torque dynamic demands. The maximum output voltage to the servo motor is 500 V, and the maximum achievable output frequency is 1000 Hz, supporting high-speed servo motor operation for high-precision automation equipment.

1. Pre-operation Safety Requirements

Only qualified electrical and automation technicians are permitted to perform installation, wiring, commissioning and maintenance. Cut off the DC bus power and 26 VDC control power supply before opening the cabinet or disconnecting any connectors. Maintain a minimum waiting period for internal capacitors to fully discharge to avoid electric shock hazards. Implement proper protective earthing for the drive unit to satisfy EMC specifications. Prevent electrostatic discharge when touching circuit boards. Do not plug or unplug power terminals, encoder cables and SERCOS communication cables under powered status. Verify no foreign conductive debris inside the drive compartment prior to power-on.

2. Pre-power Inspection Checklist

Confirm the DC bus voltage supplied by HMV rectifier modules stays within the 530～670 VDC range. Check that auxiliary control voltage maintains 26 VDC nominal. Inspect tightness of all power wiring terminals and motor cable connections. Verify shielding of motor power cables and encoder cables is grounded properly. Confirm SERCOS fiber optic links are intact and correctly routed without sharp bending. Check cooling fan function and ensure sufficient ventilation space around the drive to avoid overheating. Confirm all emergency stop circuits, limit switches and safety interlock signals are wired and functional. Verify matching parameters between servo motor specifications and drive configuration.

3. Power-on & Initial Commissioning Steps

Switch on the 26 VDC control power supply firstly, then energize the shared DC bus system. Observe drive LED indicators to confirm normal initialization without alarm codes. Establish communication via engineering software through SERCOS fiber interface. Load matched firmware and motor parameter sets to the drive. Complete auto-tuning for current loop, speed loop and position loop to optimize dynamic response. Set operation mode including position control, speed control or torque control according to machine requirements. Configure current limitation: continuous 40 A and peak 75 A shall not be exceeded for long-duration operation. Set maximum output frequency up to 1000 Hz based on motor rated speed. Execute low-speed jog test without load to inspect rotation direction, encoder feedback and mechanical interference. After no-load verification, carry out gradual load test step by step.

4. Normal Operation Specifications

Operate within the defined DC bus voltage window to prevent under-voltage or over-voltage alarms. Avoid continuous operation under peak 75 A current; peak current is only allowed for short-time acceleration and deceleration processes. Keep the switching frequency at 4 kHz as factory default for stable current output. Continuously monitor drive temperature, fan operating status and real-time output current during long-run production. Record fault codes instantly once abnormalities occur. Do not arbitrarily modify protection parameters such as overcurrent, overvoltage and over-temperature thresholds. Maintain stable SERCOS communication to guarantee synchronized multi-axis motion execution.

5. Shutdown Procedure

Execute controlled axis stop commands via upper controller firstly and wait for axes to come to a complete standstill. Disable drive pulse output and release servo enable signal. Cut off DC bus power supply first, then disconnect the 26 VDC control power. For long-term equipment downtime, isolate the drive unit from the power distribution system.

6. Fault Handling & Maintenance

When overcurrent, overvoltage, overheating or communication failures trigger alarms, stop operation immediately and cut off power supply for troubleshooting. Check cable damage, motor short circuit, mechanical jamming and cooling system failures corresponding to alarm information. Do not repeatedly power on for trial runs if hardware damage is suspected. Perform regular maintenance: clean fan dust accumulation, check terminal tightness, inspect cable aging and verify communication fiber condition. If firmware update is required, strictly follow official update procedures and avoid power interruption during downloading.

7. Key Operation Restrictions

This drive relies on a shared DC bus HMV rectifier system; direct connection to three-phase AC mains is prohibited. Do not operate beyond ambient temperature limits without current derating. Prevent vibration and liquid ingress into the drive cabinet. Unmatched servo motors and encoder systems cannot be matched for operation.
