User manual for the Inovance CHV series PG card, detailing installation, wiring, and configuration for encoder signal processing.
This document is the user manual for the PG card (PG 卡), a modular accessory for the Inovance CHV series vector-type variable frequency drives (VFDs). The card is designed to handle two orthogonal encoder signals, supporting differential, open-collector, and push-pull output types. It also provides a +12V power supply for the encoder and features a frequency divider function with selectable ratios from 1 to 256 via onboard DIP switches.
The manual provides specific instructions on physical installation, including mounting dimensions and screw requirements. It details the terminal assignments for power, input signals, and frequency-divided output signals. Additionally, it includes wiring diagrams and precautions for connecting various encoder types and ensuring signal integrity by separating signal lines from power lines. This manual is written in Chinese.
| Output Impedance | Approx. 300 Ohms |
