CIMR-G3A2L45

CIMR-G3A2L45 belongs to Yaskawa discontinued Varispeed 616G3 full digital low-noise general-purpose inverter series, 200V voltage class, originally OEM customized specification for machine tool and special equipment spindle drive, no standard universal counterpart model in regular G3 product lineup. This model has been phased out of official production, mainly applied for old CNC lathe, machining center equipment maintenance and spare part replacement.

Description

1. Product Overview

CIMR-G3A2L45 belongs to Yaskawa discontinued Varispeed 616G3 full digital low-noise general-purpose inverter series, 200V voltage class, originally OEM customized specification for machine tool and special equipment spindle drive, no standard universal counterpart model in regular G3 product lineup. This model has been phased out of official production, mainly applied for old CNC lathe, machining center equipment maintenance and spare part replacement.

2. Model Coding Definition

  • CIMR: Fixed prefix for all Yaskawa AC inverter

  • G3: Varispeed 616G3 classic all-digital inverter series

  • 2A: Three-phase AC 200V~230V input voltage grade

  • 2L45: Custom OEM specification code, exclusive hardware circuit and factory pre-set fixed control program tailored for end-user equipment, cannot be directly replaced by standard G3 serial inverters with regular digit marking (such as 23P7,27P5 etc.)

3. Core Electrical Specifications

Input power: Three-phase AC 200~230V, 50/60Hz, allowable input voltage fluctuation ±10%
Output: Three-phase variable voltage 0~230V, maximum output frequency up to 400Hz for high-speed spindle operation; rated matching motor power is 7.5kW, rated output current 33A
Control mode: Original V/F multi-point curve control with low-speed torque boosting, optimized for intermittent start-stop of machine spindle and turret motor; built-in dynamic braking transistor to connect external braking resistor for rapid spindle stop.

4. Protection Functions

Complete protection logic including overcurrent, overvoltage, undervoltage, thermal overheat, output short-circuit, input phase-loss and motor overload protection; supports stall prevention during heavy-load acceleration and deceleration.

5. Environmental & Installation Parameter

Protection rating IP20, forced air cooling with built-in cooling fan, only indoor cabinet installation permitted; operating ambient temperature range 0℃~50℃, relative humidity 20%~80%RH without dew condensation, installation altitude below 1000 meters.

6. Application Range

Primarily equipped on vintage Mazak, Okuma and other imported CNC turning/milling centers, dedicated to spindle or turret indexing drive, widely used for equipment overhaul and spare replacement of old-generation Japanese machine tools.
