Physical & Electrical Performance Parameters

Deterministic Fieldbus Integration & Motor Drive Dynamics

High starting torque and vector control capabilities in open loop mode deliver precise machine dynamics and motion profiles. The drive supports open network fieldbus communication options, enabling real-time status exchange and setpoint transfer over EtherNet/IP deterministic networks. Backplane bus communication velocity across optional option cards ensures low-latency register access, while firmware flash compatibility guarantees predictable motor speed response during multi-axis synchronization.

Installation & Wiring Guidelines

• Enclosure Clearance: Mount the unit vertically on a flat panel inside an IP54 or higher control cabinet, maintaining a minimum 100 mm top and bottom clearance for thermal dissipation.
• AC Line Reactor Wiring: Connect an optional AC reactor to the main supply lines to suppress harmonic current generated from the inverter, especially if power supply capacity exceeds drive capacity.
• DC Choke Configuration: Install a DC reactor across the internal DC link terminals for improved harmonic mitigation compared to standard AC line reactors.
• Motor & Line Grounding: Route input power cables (3-phase 380 to 480 VAC) and motor power leads in separate grounded metallic conduits to avoid high-frequency noise coupling.

Frequently Asked Questions

• What limits exist on the maximum output voltage supplied to the AC motor?

  The output voltage ranges up to 3-phase 380 to 480 VAC and cannot exceed the incoming line voltage under any operational state.

• What constraint applies when using the 3G3AX-NFI23 filter option with this drive?

  When configured with the 3G3AX-NFI23 noise filter option, only the Heavy Duty (CT) rating specification is supported.

• What is the maximum allowable duty cycle for internal dynamic braking?

  The built-in dynamic braking transistor circuit operates with a maximum braking resistor duty cycle (BRD usage) of 10%.

• How can harmonic current generation be minimized effectively?

  A DC reactor suppresses harmonic current better than an AC reactor, and both components can be installed simultaneously for maximum reduction.

• When should an AC reactor be connected to the AC power input lines?

  Connect an AC reactor if power supply capacity greatly exceeds inverter rating, or if power factor improvement is required.

• Does the inverter support closed-loop encoder feedback for speed control?

  The drive delivers high starting torque and precise torque regulation strictly in open loop mode without requiring encoder feedback.

• What process control features are integrated directly into the firmware?

  The unit features internal PID control, multi-step speed selection, starting frequency adjustment, carrier frequency adjustment, and jogging operation modes.

• How are fieldbus communications integrated into the drive platform?

  Optional communication cassettes interface directly with major open network systems, connecting the drive to field controllers.
