PG Card (Encoder1387)

The EM760-PG-S1 is an expansion card designed for SINEE’s EM760 series variable frequency drives (VFDs), providing interface support for SinCos (sine-cosine) incremental encoders. This card enables highly accurate speed and position feedback, essential for advanced closed-loop vector control applications in demanding industrial environments.

Key Features

• SinCos Encoder Interface: Supports industry-standard sine-cosine signal encoders for precise real-time speed and position feedback.

• Enhanced Control: Enables closed-loop vector control (FVC) by allowing the EM760 VFD to read high-resolution encoder signals for optimised performance and control accuracy.

• Plug-and-Play: Easily installable as an option module on the EM760 series drive, with clear wiring and setup procedures.

• Robust Performance: Suitable for high-precision motion applications, improving response time, accuracy, and position holding under load.

• Typical Use Cases: Ideal for servo-drive upgrades, cranes, hoists, advanced conveyors, and any application needing precise motor regulation.

Technical Overview

• Signal Type: Differential SinCos (sine-cosine), typically 1Vpp

• Function: Provides pulse generation (PG) feedback for closed-loop and high-resolution control

• Compatibility: For use with the EM760 VFD series and compatible SinCos encoders

• Application: Used in vector control modes (especially FVC) where encoder feedback is critical for dynamic motor response and position control
