2. Electrical Specifications
Main circuit input is three-phase AC200V to 230V with allowable voltage fluctuation range of -15%~+10% and applicable for 50Hz and 60Hz power supply. Independent single-phase AC200~230V terminals are reserved for separate control circuit power supply. Rated continuous output power is 0.5kW with rated continuous output current of 3.2A. The drive supports 300% peak overload current of 9.6A lasting for maximum 3 seconds and 150% overload sustainable up to 60 seconds. Nominal DC bus voltage is DC280V~320V, and P/N terminals are reserved for external regenerative braking resistor connection under frequent heavy-load deceleration conditions.
3. Environmental and Mechanical Parameters
Operating ambient temperature ranges from 0℃ to +55℃, short-time peak working temperature shall not exceed 60℃, and storage temperature covers -20℃~+70℃. Working relative humidity is controlled between 5% and 80% without condensation. Protection grade is IP20, and the device is only allowed vertical installation inside closed electrical cabinet. Net weight is approximately 2.0kg, maximum applicable installation altitude is below 1000 meters above sea level, and the unit can resist vibration of 10Hz to 55Hz with 0.5mm amplitude.
4. Control Performance
The servo adopts IGBT sine-wave PWM dual closed-loop control including speed loop and position loop. Speed adjustment ratio reaches 1:5000 with full-load steady-state speed accuracy within ±0.01%. Digital differential pulse serves as primary position command with maximum input frequency up to 500kpps; analog speed/torque input is reserved as auxiliary alternative command. CN2 port matches multi-turn serial absolute encoder, enabling power-off position storage to cancel homing requirement after power restoration. Built-in digital notch filter suppresses mechanical resonance and operating vibration. Most basic parameters can be modified normally, while Y110 OEM customized gain and acceleration/deceleration parameters are pre-locked at factory setting. Three control modes can be switched flexibly by adjusting available parameters.
5. Interface and Communication Configuration
R/S/T terminals are used for three-phase main AC power input; U/V/W terminals connect three-phase power cables of matched servo motor; P/N spare terminals are for external regenerative brake resistor wiring. CN1 is opto-isolated digital I/O terminal block with 8 input channels and 6 relay output channels following fixed Y110 customized logic, covering servo enable, forward/reverse overtravel limit, origin signal input, emergency stop, servo ready output and fault alarm output functions. CN2 is exclusive connector for multi-turn absolute encoder feedback connection. Onboard RS422 serial port with Yaskawa proprietary communication protocol realizes parameter read/write and real-time operating status monitoring; optional expansion module supports Modbus-RTU bus networking connection.
6. Core Functions
Three control modes of position, speed and torque are freely configurable; electronic gear ratio function supports multi-axis synchronous linkage for automation equipment. Automatic motor parameter identification completes one-click testing of motor electrical parameters and rotor inertia to optimize closed-loop gain efficiently. Absolute position memory function eliminates homing after power outage to improve production efficiency. Internal integrated braking circuit absorbs most regenerative energy generated during deceleration, and external brake resistor is only required for heavy-duty frequent emergency stop scenarios. Segmented gain setting ensures stable low-speed operation and fast high-speed dynamic response. The drive automatically stores latest 10 groups of historical fault codes for maintenance reference. Y110 preset parameters are optimized for designated OEM equipment, random parameter revision without mechanical modification is not recommended.
7. Applicable Scenarios
This customized Y110 servo drive is specially developed for precision automation equipment requiring absolute position retention after power failure, including customized small CNC auxiliary feed axes, dedicated electronic component assembling machines, miniature gantry positioning equipment and special labeling automatic production lines. Direct replacement requires the identical full part number CACR-SR05SZ1SS-Y110.
8. Operation and Routine Maintenance Instructions
Before power-on, inspect all power cables, absolute encoder wires and I/O signal wiring to exclude short circuit, loose terminals and wrong connection risks. Complete motor parameter matching and debugging according to on-site mechanical load, avoid arbitrary modification of locked Y110 factory preset parameters. Keep cabinet ventilation unobstructed during operation, prohibit long-time continuous running when inner cabinet temperature exceeds 55℃, and prevent frequent repeated power on/off within short intervals. Conduct periodic maintenance every three to six months: tighten all terminal screws, check cable insulation aging and clean dust accumulated on drive heat sink and cabinet air duct. Cut off main power and wait no less than 15 minutes for full discharge of internal DC bus capacitor before any internal disassembly maintenance to avoid electric shock hazard. Stop equipment and cut off power immediately once continuous fault alarm occurs, inspect servo motor, connecting cables and mechanical jamming before restarting operation.
9. Basic Troubleshooting Guide
Overheat alarm is mainly caused by blocked heat sink, overhigh cabinet ambient temperature or long-term overload operation. Encoder fault alarm usually originates from loose CN2 connector or damaged absolute encoder feedback cable. Overvoltage fault occurs under frequent rapid deceleration with heavy load; install external regenerative braking resistor on P/N terminals to resolve the issue.
