1. What is the G691M Variable Frequency Drive Module?

The G691M is an electronic power device that controls motor operation using internal electronic switches and software. Also known as an AC drive, VSD (Variable Speed Drive), or Inverter, it provides stepless speed regulation, torque control, soft start/stop, and overload protection to meet various equipment application requirements.

2. What functions does it provide?

It offers comprehensive motor control functions including V/f, Open/Closed Loop Vector, and Direct Torque Control (DTC). Key features include a built-in PLC supporting 16 multi-step speeds, one-step sequence programming for constant pressure/temperature, an internal braking chopper (up to 160kW), and rich I/O connectivity with Modbus RTU communication.

3. What are the key parameters influencing selection?

When selecting the right G691M model, consider the Supply Voltage (1-phase 220V, 3-phase 220V, or 3-phase 380V), the Motor Power Rating (ranging from 0.75kW up to 500kW), the required Overload Capacity (150% for 120s or 180% for 10s), and the specific Application Type (e.g., heavy-duty compressor vs. general-purpose fan).

4. What are the available options for this product?

The G691M offers multiple physical configurations: K1-K4 models feature a Molded Enclosure, while K5-K12 models utilize a compact Metal Unit (Sheet metal). Protection levels can be selected between standard IP20 and optional IP65. Additionally, an optional low-temperature operation upgrade allows usage in environments down to -20°C.

5. What standards does it meet and which markets is it designed for?

The G691M is designed for global industrial markets, complying with IP20 open type and IP65 protection standards. Its wide voltage compatibility (200-240V and 380-440V) and Modbus RTU communication make it suitable for international automation, processing, and heavy-duty machinery sectors.

6. What are the installation precautions?

Ensure the drive is installed in an environment within the ambient temperature range of -10°C to 40°C (without derating) or up to 60°C (with derating). Maintain proper cabinet ventilation for heat dissipation. Humidity must be kept under 90% HR without condensation. For cabinet mounting, refer to the specific L1/W1 installation dimensions corresponding to the shell model (K1-K12).
