Description

1.Model Coding Explanation

CACR：Yasnac VS800 full-digital CNC feed-axis AC Servopack series for machine tool OEM matching

SR：Hardware reserves dual command input circuit（±10V analog + differential pulse）, Y114 firmware locks fixed control mode

15：Rated 1.5kW, AC200V grade, continuous rated output current 11.7Arms

BB：Standard mainboard & universal I/O base PCB layout

1：3-phase AC200~230V main power input; independent single-phase AC200V control power supply

AM：CN2 port hardware dedicated for absolute serial encoder, onboard 3.6V backup battery socket for absolute position retention after power-off

Y114：Exclusive OEM fixed customized firmware variant, all core motion parameters factory-locked, user unauthorized parameter modification prohibited, fixed I/O definition tailored for designated CNC machine brand

2.Basic Electrical Specifications

Three-phase main input AC200~230V, 50/60Hz, allowable voltage fluctuation -15%~+10%. Separate single-phase AC200V feeds control circuit individually.

Overload rating: 150% rated current sustainable for 60s, 300% peak overload limited within 3s during startup. DC bus nominal voltage DC280~320V; terminals P-BN for external regenerative braking resistor connection for frequent deceleration working condition.

IGBT sine-wave PWM modulation, max output frequency 300Hz, IP20 protection grade for vertical cabinet installation, unit net weight approx 3.3kg.

3.Core Customized Features of Y114 Version

Fixed default control mode: factory locked ±10VDC analog speed control, pulse position control function disabled via firmware and cannot be activated by onsite parameter setup; torque control also locked unavailable.
Absolute encoder matching fixed for specified OEM servo motor only, factory preset encoder resolution and battery low-voltage threshold; auto-tuning function partially restricted, full motor parameter auto-identification invalid, only tiny current loop fine-tuning accessible.
All loop parameters fixed solidly: position loop gain, speed loop gain, acceleration/deceleration time constant, anti-resonance filter frequency/gain pre-calibrated per OEM mechanical structure, locked without edit permission.
CN1 I/O pin definition fully fixed by Y114 OEM rule, digital input/output function cannot be remapped via parameters, different from standard open AM general model.
RS422 serial communication only supports reading running status and fault history data; parameter upload/download & write operation blocked by factory firmware lock.
AM exclusive absolute battery detection reserved: low backup battery voltage triggers dedicated alarm to remind periodic battery replacement every 2~3 years.

4.Installation & Ambient Requirements

Operating ambient temperature 0℃~+40℃（Y114 OEM narrow temp range vs standard 0~55℃）; storage temperature -20℃~+70℃, working humidity 5%~80%RH non-condensing. Derate load when mounting altitude over 1000m above sea level.

Anti-vibration:10~55Hz, single amplitude 0.5mm; reserve ≥50mm vacant space top & bottom for heat dissipation inside cabinet.

Cut all input power and wait minimum 15min for internal DC bus capacitor full discharge before cover disassembly or CN1/CN2 wiring; hot plug of connectors under powered state strictly forbidden.

5.Terminal & Connector Definition

R/S/T: three-phase main AC power input terminals; U/V/W: motor three-phase power output terminals.

P & BN: external braking resistor connecting terminals for rapid deceleration overvoltage suppression.

CN1: opto-isolated digital I/O port with fixed Y114 pin assignment, no editable signal mapping.

CN2: dedicated absolute serial encoder feedback port with onboard backup battery wiring pin, only original OEM matched absolute encoder cable usable.

Front single-digit seven-segment LED displays real-time operating status and standard VS800 series fault codes plus Y114 exclusive low-battery alarm code.

6.Full Protection Functions

Built-in complete protection: output overcurrent, DC bus overvoltage/undervoltage, drive overheat, absolute encoder disconnection, backup battery undervoltage, motor overload, CPU abnormal error. Latest ten fault codes permanently stored without power-loss data missing.

Internal dynamic brake circuit equipped; external braking resistor mandatory on P-BN under heavy cyclic load and frequent emergency stop to eliminate deceleration overvoltage fault.

7.Replacement & Maintenance Specification

Direct replacement only allows identical full model CACR-SR15BB1AM-Y114; standard CACR-SR15BB1AM or AF variant cannot substitute directly due to locked firmware & fixed I/O difference, replacement needs manufacturer rewrite Y114 exclusive firmware professionally.

Daily pre-operation inspection: check tightness of power cable and CN1/CN2 plug; clean radiator dust every 3~6 months to avoid overheat shutdown. Replace absolute encoder 3.6V backup battery every 2~3 years to prevent origin data loss after power failure.

Factory full parameter reset is strictly prohibited on Y114 unit; reset will erase OEM locked custom data and cause abnormal machine running.

8.Common Troubleshooting Guide

Overheat alarm: radiator dust accumulation, poor cabinet ventilation or long-term overload; clean cooling fin or reduce actual working payload.

Encoder fault: loose CN2 plug, damaged feedback cable or mismatched non-OEM motor; rewire connector or replace designated matched absolute motor.

AM exclusive low battery alarm: insufficient backup battery voltage; replace specified 3.6V lithium battery promptly.

Deceleration overvoltage alarm: add external regenerative resistor between P and BN terminals.

Overload alarm: mechanical transmission jamming or excess load; inspect mechanical structure and reduce equipment load.

Parameter mismatch alarm: triggered by unauthorized parameter modification; only factory professional setup can restore original locked setting.
