CIMR-G5C4011

CIMR-G5C4011 belongs to discontinued Yaskawa Varispeed 616G5 high-performance flux vector inverter lineup; the suffix C stands for CNC spindle customized specification, specially optimized for machine tool spindle high-speed operation instead of general-purpose drive. Original production is discontinued, mostly supplied as refurbished/used spare parts for old imported CNC lathes and machining center maintenance.

Description

1. Product Introduction

CIMR-G5C4011 belongs to discontinued Yaskawa Varispeed 616G5 high-performance flux vector inverter lineup; the suffix C stands for CNC spindle customized specification, specially optimized for machine tool spindle high-speed operation instead of general-purpose drive. Original production is discontinued, mostly supplied as refurbished/used spare parts for old imported CNC lathes and machining center maintenance.

2. Model Coding Definition

  • CIMR: Fixed part number prefix of Yaskawa AC inverter

  • G5: Varispeed 616G5 full digital flux vector series

  • C: Special spindle dedicated version (optimized for high-frequency spindle drive)

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

  • 011: Rated 11kW constant torque matching asynchronous spindle motor

3. Core Electrical Ratings

  • Rated matched motor power: 11kW (CT constant torque); max adaptable light-load variable torque up to 15kW

  • Rated output capacity: 18kVA, rated output current: 27A

  • Input: 3-phase AC 380~460V, 50/60Hz, allowable voltage deviation ±10%

  • Output: 0~460V variable three-phase AC, maximum output frequency up to 400Hz for high-speed spindle cutting

  • Control modes: Multi-point V/F curve, open-loop sensorless vector, closed-loop flux vector control (requires optional PG encoder feedback card); built-in full auto-tuning for motor parameter automatic identification

  • Built-in dynamic braking chopper inside the unit; external braking resistor can be wired for fast spindle emergency stop

  • Overload capability: 150% rated current sustainable for 60 seconds under heavy spindle cutting load

4. Complete Protection Functions

Full industrial protection including overcurrent, overvoltage, undervoltage, heatsink overheat, motor overload, output short-circuit, input phase loss and ground fault protection; built-in acceleration/deceleration stall prevention and speed search function to avoid unexpected shutdown during fluctuating cutting load.

5. Communication & Terminal Configuration

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

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

  • Multiple digital input terminals, dual analog input (0~10VDC / 4~20mA), pulse reference input, multi-function relay fault signal output terminal; compatible with JVOP-130 digital operation panel for parameter setting and running monitoring

6. Mechanical & Environmental Parameters

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

  • Net weight: approx.12kg; overall dimension: 310(W)×480(H)×210(D)mm

  • Operating ambient: 0℃~50℃ working temperature, relative humidity 20%~80% non-condensing, rated installation altitude below 1000 meters

7. Application Range

Exclusively for spindle driving of old imported CNC milling machine, machining center, vertical lathe and high-speed automation processing equipment; used for equipment overhaul and spare replacement of legacy production lines.
