This lesson covers the fundamental steps required to commission a Siemens G120C drive.

Whether you are starting with a new unit or recovering from a factory reset, these steps ensure the drive accurately matches your motor specifications and is reachable on your network.

Phase 1: Basic Setup and Standards

The first step in commissioning is defining the regional standards. This determines the units (HP vs. kW) and base frequencies (60Hz vs. 50Hz) used during the process.

  • Language Selection: Choose English to navigate the menus.

  • Quick Setup: Access this menu to begin the guided commissioning.

  • Factory Reset: If the drive was previously used, select "Reset to Factory Settings" to ensure no old parameters interfere with your new configuration.

  • Motor Standard: Select Nema 60 Hz US for North American applications.

Phase 2: Entering Nameplate Data

Inputting accurate motor data is critical for the drive's control algorithms. For this specific trainer setup, use the following values:

  • Motor Type: Induction three-phase motor.

  • Supply Voltage: 230V.

  • Motor Current: 0.18 Amps.

  • Motor Power: 0.0 HP (Fractional).

  • Motor Speed: 3300 RPM.

Phase 3: Motor Identification and Testing

After saving the parameters, the drive must "learn" the electrical characteristics of the motor.

  1. Motor ID Test: This procedure calibrates the drive to the specific motor connected. Note that the motor will rotate during this process.

  2. Hand Mode: Use the manual controls on the keypad to verify rotation.

  3. Direction Check: Confirm the motor rotates counter-clockwise when viewed from the front.

Phase 4: Network Configuration

To communicate with a PLC, the drive requires a unique IP address.

  • Tooling: Use the SIM IP discovery tool to find the drive on the network.

  • Assignment: Assign the default IP address 192.168.1.12.

  • Execution: Finalize the IP change to enable industrial ethernet communication.
