Product Overview

Key Features

• Dual control modes: Isochronous mode for standalone constant speed operation, and droop mode for grid parallel connection and load sharing.

• High control accuracy: Speed regulation error within ±0.25%, equipped with adaptive PID algorithm. Speed input range: 0.5–32000 Hz.

• Complete I/O configuration: 2 MPU/proximity speed inputs, 8 analog inputs (4–20 mA), 20 discrete inputs; 2 actuator outputs (4–20 mA / 20–200 mA), 8 relay outputs.

• Multiple protection functions: Overspeed trip, critical speed avoidance, soft start and valve position limiting. It supports 15 shutdown fault inputs and 15 alarm inputs with first-out fault recording.

• Communication ports: RS-232 and RS-485 interfaces, compatible with Modbus RTU and ASCII protocols for remote monitoring and parameter configuration.

• Industrial reliability: IP20 protection rating, wide operating temperature range. Certified with CE, UL and compliant with SIL2 safety standard.
