Product Introduction
The Elmo G-TUB30/480FEHSNA2 is a high-performance digital servo drive engineered for demanding industrial motion control applications. It delivers 30kW of continuous power from a compact form factor, making it ideal for robotics, CNC machinery, and semiconductor equipment where space is limited but power density is critical. The drive accepts 3-phase 400-480VAC input and provides precise current, velocity, and position control loops.Unlike conventional drives, the Elmo G-TUB30/480FEHSNA2 achieves ≥98% conversion efficiency through advanced power management, significantly reducing heat generation and energy costs. It supports EtherCAT and CANopen for real-time multi-axis synchronization, and includes comprehensive protection against overvoltage, overcurrent, and overtemperature conditions. The 60A peak output current enables high dynamic response for rapid acceleration and deceleration profiles.
Installation & Configuration Guide
Preparation (15 min)
Verify the Elmo G-TUB30/480FEHSNA2 matches your motor’s voltage and current ratings. Confirm 3-phase 400-480VAC supply is available and properly fused. Gather shielded motor cables, EtherCAT cables, and appropriate torque tools. Self-correction: Always measure the incoming AC voltage before connecting—voltage outside the ±10% tolerance can damage the internal power stage.Removal (5–10 min)
Lock out and tag out all power sources. Wait 5 minutes for DC bus capacitors to discharge (verify with a multimeter before touching). Disconnect motor cables, power input, and communication cables. Remove mounting hardware and carefully extract the drive from the cabinet. Inspect the heatsink fins for dust accumulation or damage.Installation (10 min)
Mount the Elmo G-TUB30/480FEHSNA2 vertically in the cabinet with adequate clearance for airflow (minimum 50mm above and below). Secure mounting screws to specified torque. Connect shielded motor cables using proper grounding clamps. Connect EtherCAT cable to the designated IN port. Verify all connections are tight and strain-relieved.Power-On & Test (15 min)
Apply control power first (24VDC if applicable), then main AC power. Observe the drive status LED for normal initialization. Use Elmo Motion Studio or Composer software to verify communication via EtherCAT. Run the motor auto-tuning routine to optimize current loop gains. Perform a no-load rotation test, then gradually increase load while monitoring current and temperature.
Troubleshooting Quick Reference
| Symptom | Probable Cause | Immediate Action |
|---|---|---|
| Overcurrent Fault | Motor short or ground fault | Measure motor winding resistance. Check cabling. |
| Overvoltage Fault | Deceleration too fast or no brake resistor | Add braking resistor. Reduce decel rate. |
| No Communication | EtherCAT cable or config error | Check cable continuity. Verify node address. |
| Overtemperature | Insufficient cooling or overload | Check fan operation. Reduce duty cycle. |
| Position Error | Encoder wiring or tuning issue | Verify encoder signals. Re-run auto-tune. |
Dimensions, Mounting & Wiring Notes
- Dimensions: Verify exact dimensions from Elmo datasheet (varies by revision)
- Mounting: Vertical orientation required. Standard cabinet mounting with M4/M5 screws.
- Terminal Notes: Use shielded cables for all motor and encoder connections. Real-world detail: The power terminals are typically located on the bottom of the unit; if your cable entry is from the top, use proper cable glands to maintain IP20 rating and prevent strain on the terminals. The EtherCAT port is usually on the front panel near the status LED.
FAQ
What motor is compatible with the G-TUB30/480FEHSNA2?
This drive supports brushless DC, AC servo, and linear motors. Verify that the motor’s rated voltage matches 400-480VAC and that continuous current does not exceed 60A. Consult the Elmo motor compatibility matrix for specific part numbers.Do I need a braking resistor?
If your application involves frequent deceleration or vertical loads, yes. The internal braking circuit requires an external resistor to dissipate regenerative energy. Size the resistor based on your deceleration energy calculations.Can I use this drive with a non-Elmo motor?
Yes. The G-TUB30/480FEHSNA2 is compatible with most brushless motors. However, you will need to manually configure commutation, encoder type, and current limits in Elmo Motion Studio. Auto-tuning may require additional parameters for non-Elmo motors.How do I update the firmware?
Connect via USB or EtherCAT and use Elmo Motion Studio. Download the latest firmware from the Elmo support portal. Never interrupt the firmware update process—power loss during update can brick the drive.What is the difference between FEHSNA2 and other revisions?
The suffix indicates specific hardware options, communication protocols, and regional certifications. FEHSNA2 typically denotes EtherCAT communication with specific safety or I/O configurations. Cross-reference the full part number with your existing system to ensure compatibility.I’m getting intermittent overcurrent faults. What should I check?
First, measure motor insulation resistance (should be >10 MΩ). Check all cable connections for looseness or corrosion. Verify the motor cable shield is properly grounded at both ends. If the fault persists, the drive’s IGBT module may be degraded and require replacement.Does this drive support safety functions like STO?
Safety function availability depends on the specific suffix. Check the datasheet for your exact model number. If STO is required and not present, you must use external safety relays or upgrade to a safety-certified variant.
