Applicable motor power: standard load 90kW, heavy load 75kW.

Power supply specifications: three-phase 380 - 480V (±15% - ±10%), frequency 50 - 60Hz (±5%).

Protection level: IP21, suitable for installation in indoor control cabinets.

Installation method: wall-mounted.

Performance parameters

Output current: Under standard load, 156.2A at 380V, 135.8A at 480V; under heavy load, 134.3A at 380V, 118.1A at 480V.

Overload capacity: standard load 110% for 60 seconds, 150% for 2 seconds; heavy load 150% for 60 seconds, 180% for 2 seconds.

Output frequency range: 0.1 - 599Hz.

Input / Output interface

Digital input: multiple programmable inputs, support 24V DC, used to control the basic operation of the inverter.

Analog input: usually 3, support 0 - 10V or 4 - 20mA input, can receive external speed given signal.

Analog output: 2, 0 - 10V or 4 - 20mA, can output frequency, current and other parameters for monitoring.

Relay output: 3, 250V AC/3A, used for alarm or status indication.

Communication interface: Modbus RTU (RS485) and Modbus TCP (Ethernet) are standard, and expansion cards such as Profibus DP, DeviceNet, and Ethernet/IP are optional, which facilitates communication with the host computer or other devices.

Features

High-performance control: Supports sensorless vector control (SVC) and closed-loop vector control (FOC), providing precise torque and speed control.

Energy monitoring: Built-in energy meter function, which can monitor energy consumption in real time and facilitate energy management.

Multi-motor control: Can drive multiple motors at the same time for synchronous or independent control.

Integrated safety function: Supports functions such as safe torque cancellation (STO) and safe stop (SS1), meeting SIL3/PLe safety level.

Intelligent PID control: Built-in PID regulator, supporting closed-loop control such as pressure, flow, and temperature.

Automatic parameter backup: Supports fast copying of parameters via USB or memory card, simplifying debugging and maintenance.
