Installation and Wiring
Proper installation is critical for the module's performance and safety. Follow these general guidelines:
- Power Off: Ensure the inverter and all connected equipment are powered off before installation.
- Module Mounting: Securely attach the PG expansion module to the designated expansion slot on the INVT inverter.
- Wiring Connections: Connect the PG feedback signals (e.g., A, B, Z phases, VCC, GND) from the motor or encoder to the corresponding terminals on the module. Refer to the specific wiring diagram for your inverter model and encoder type.
- Grounding: Ensure proper grounding of the module and connected equipment for safety and noise reduction.
- Power On: After verifying all connections, power on the inverter and the system.
Wiring Diagram Description:
The wiring diagram illustrates the connections between the PG encoder and the expansion module. It typically shows terminals for power supply (VCC, GND), signal phases (A+, A-, B+, B-, Z+, Z-), and potentially shield connections. Ensure correct polarity and signal integrity.
Note: Always refer to the specific wiring diagrams provided with your INVT inverter and PG encoder for detailed instructions.
Operation and Configuration
Once installed, the PG module's parameters need to be configured within the inverter's control settings. This typically involves setting the PG pulse count per revolution and selecting the PG type (e.g., incremental encoder).
Parameter Settings:
- PG Pulse Count: Input the number of pulses generated by the encoder per revolution of the motor shaft.
- PG Type: Select the appropriate encoder type (e.g., differential, open collector).
- PG Feedback Direction: Configure the direction of feedback if necessary.
Refer to the INVT inverter's user manual for detailed instructions on accessing and modifying these parameters.
Troubleshooting
Common issues and potential solutions:
- No PG Signal: Check wiring connections, encoder power, and encoder functionality. Ensure the correct PG type is selected in the inverter parameters.
- Incorrect Speed/Position: Verify the PG pulse count setting. Ensure the encoder is correctly mounted and the shaft is not slipping.
- Module Not Recognized: Confirm the module is properly seated in the expansion slot. Check for any physical damage.
