CIMR-G5A4045

CIMR-G5A4045 belongs to discontinued Yaskawa Varispeed 616G5 high-performance flux vector inverter series, standard 400V voltage grade model. This full-digital AC drive supports V/F control, open-loop sensorless vector and closed-loop flux vector control with high low-speed torque output, widely used for heavy-duty industrial equipment retrofitting and legacy CNC machine maintenance replacement. Original production has been stopped, available mainly via refurbished or surplus spare parts for after-market service.

Description

1. Product Overview

CIMR-G5A4045 belongs to discontinued Yaskawa Varispeed 616G5 high-performance flux vector inverter series, standard 400V voltage grade model. This full-digital AC drive supports V/F control, open-loop sensorless vector and closed-loop flux vector control with high low-speed torque output, widely used for heavy-duty industrial equipment retrofitting and legacy CNC machine maintenance replacement. Original production has been stopped, available mainly via refurbished or surplus spare parts for after-market service.

2. Model Code Definition

  • CIMR: Fixed prefix of Yaskawa general AC inverter

  • G5: Varispeed 616G5 full digital high-performance vector series

  • A: Standard general specification without customized factory programming

  • 4: Three-phase AC 380~460V (400V class) input voltage

  • 045: Rated power code matching 45kW standard asynchronous motor

3. Key Electrical Specifications

  • Matched standard motor power: 45kW (constant torque rating); 55kW under variable torque light-load condition

  • Rated output capacity: 73kVA; Rated output current: 96A

  • Input: Three-phase AC 380V~460V, 50/60Hz, permissible input fluctuation ±10%

  • Output: Three-phase variable AC 0~460V; maximum adjustable output frequency up to 400Hz for high-speed spindle operation

  • Control options: Multi-point V/F curve, sensorless vector control, closed-loop flux vector control (needs external PG encoder feedback card); built-in motor auto-tuning function for automatic motor parameter identification

  • Built-in dynamic braking transistor terminal; external braking resistor or separate braking unit can be configured for fast deceleration and emergency stop; no internal built-in braking resistor

4. Protection Functions

Full-set industrial protection logic including overcurrent, overvoltage, undervoltage, heatsink overheat, motor overload (150% rated current sustain for 60s), output short-circuit, input phase loss, ground fault protection; equipped with acceleration/deceleration stall prevention to avoid unexpected shutdown under heavy fluctuating load.

5. Communication & Terminal Configuration

  • Standard onboard MEMOBUS (Modbus-RTU) serial communication interface

  • Optional expansion cards: PG speed feedback card, Profibus-DP, CC-Link, DeviceNet communication adapter

  • Multi-channel digital input terminals, dual analog input (0~10VDC / 4~20mA), pulse input, multi-function relay fault signal output terminal

6. Mechanical & Environmental Parameters

  • Protection class: IP20, forced air cooling with built-in large-size cooling fan; cabinet indoor installation only

  • Dimension: 340(W) × 630(H) × 280(D) mm; net weight approx.44kg

  • Working ambient: 0℃~50℃ operating temperature, relative humidity 20%~80% non-condensing, installation altitude below 1000m

7. Typical Application Fields

Heavy-duty CNC machine spindle drive, large conveyor system, extruder, industrial fan & water pump, metallurgical auxiliary equipment and packaging heavy machinery speed regulation; mostly applied for overhaul of old imported industrial production lines and machine tools.
