OMRON/YASKAWA VZA47P5FAA / CIMR-VZ4A0023FAA V1000 Compact Inverter

Overview

The OMRON/YASKAWA VZA47P5FAA / CIMR-VZ4A0023FAA is a V1000 series compact sensorless vector inverter, manufactured by Yaskawa for Omron under the OYMC joint venture. The OMRON/YASKAWA VZA47P5FAA / CIMR-VZ4A0023FAA is rated 7.5kW heavy duty and 11kW normal duty for three-phase 380V to 480V AC supply. It supports sensorless vector control for asynchronous motors and permanent magnet motors, delivering high starting torque at low speed. The OMRON/YASKAWA VZA47P5FAA / CIMR-VZ4A0023FAA is widely stocked as spare drive for fan, pump, conveyor and general automation retrofits.

Features

The OMRON/YASKAWA VZA47P5FAA / CIMR-VZ4A0023FAA provides 200% torque at 0.5Hz for heavy load startup. It integrates built-in EMC filter and safe torque off function, and supports auto-tuning for induction and PM motors. The OMRON/YASKAWA VZA47P5FAA / CIMR-VZ4A0023FAA has RS485 Modbus communication as standard, with optional expansion cards for PROFIBUS DP, EtherCAT, DeviceNet and PROFINET. It includes full protection including overcurrent, overvoltage, undervoltage, overheat, motor overload and ground fault detection. The OMRON/YASKAWA VZA47P5FAA / CIMR-VZ4A0023FAA uses standard vertical cabinet mounting and shares the same parameter software as Yaskawa V1000 platform.

Specs

Device Type: V1000 compact sensorless vector inverter Model: OMRON/YASKAWA VZA47P5FAA / CIMR-VZ4A0023FAA Heavy Duty Rating: 7.5 kW Normal Duty Rating: 11 kW Input Voltage: 3 × 380 V AC to 480 V AC, 50/60 Hz Control Mode: V/f control, sensorless vector control, PM motor control Standard Communication: Modbus RS485 Safety Function: STO safe torque off Protection Grade: IP20 Mounting: Vertical installation inside control cabinet Application: Conveyor, pump, fan, packaging machine, general variable speed drive

Principle

The OMRON/YASKAWA VZA47P5FAA / CIMR-VZ4A0023FAA receives frequency setpoint via terminal signals or Modbus bus. The internal control unit calculates the required voltage and frequency and drives the IGBT power module to output PWM waveform to the motor. It estimates motor speed and flux without encoder feedback through sensorless vector algorithm. The inverter continuously monitors current, bus voltage and internal temperature. When fault conditions are detected, the OMRON/YASKAWA VZA47P5FAA / CIMR-VZ4A0023FAA cuts off output and stores fault code for diagnosis.

Applications

The OMRON/YASKAWA VZA47P5FAA / CIMR-VZ4A0023FAA is used for variable speed regulation of fans, water pumps and conveyors in industrial plants and building HVAC systems. It serves economical speed control for light and medium duty automation feeders. The OMRON/YASKAWA VZA47P5FAA / CIMR-VZ4A0023FAA applies to spare stock and emergency repair of existing Omron / Yaskawa V1000 drive assemblies. It also supports cabinet renovation and energy saving transformation projects.
