2. Electrical Specifications
Main circuit power input is three-phase AC200V~230V with permissible voltage fluctuation ranging from -15% to +10%, suitable for 50Hz and 60Hz power supply. Independent single-phase AC200~230V terminals are available for separate control circuit power supply. Continuous rated output current is 5.8A; peak 300% overload current can last maximum 3 seconds while 150% overload can be continuously sustained for 60 seconds. Nominal DC bus voltage ranges DC280V~320V, and P/N spare 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 cannot exceed 60℃, and storage temperature covers -20℃~+70℃. Working relative humidity is maintained between 5% and 80%RH without condensation. Protection grade is IP20 and vertical installation inside sealed electrical cabinet is required only. Net weight is approximately 2.1kg, maximum applicable installation altitude is below 1000 meters above sea level, and the unit can withstand 10~55Hz vibration with 0.5mm single amplitude.
4. Control Performance
The servo adopts IGBT sine-wave PWM dual closed-loop control consisting of speed loop and current loop. Speed adjustable ratio reaches 1:5000 with full-load steady-state speed accuracy controlled within ±0.01%. Users can select either differential pulse or analog voltage as operation command flexibly. CN2 port supports incremental encoder as primary feedback and is hardware compatible with serial absolute encoder due to Z-type circuit design. Built-in digital notch filter suppresses mechanical resonance and operating vibration. Automatic motor parameter identification function detects motor electrical parameters and rotor inertia to optimize closed-loop gain automatically. Y01A customized gain and acceleration/deceleration parameters are pre-locked at factory setting.
5. Interface and Communication Configuration
R/S/T terminals are 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 Y01A OEM customized definition, covering servo enable, forward/reverse overtravel limit, origin signal input, emergency stop, servo ready output and fault alarm output functions. CN2 is dedicated connector for encoder feedback connection. Onboard RS422 serial port with Yaskawa proprietary communication protocol realizes parameter reading, writing and real-time running status monitoring.
6. Core Functions
Three control modes can be freely switched and electronic gear ratio function supports multi-axis synchronous linkage for automation equipment. Absolute position memory eliminates compulsory homing after power outage to improve production efficiency. Internal integrated braking circuit absorbs most regenerative energy generated during deceleration; external brake resistor is only required for heavy-duty frequent emergency stop scenarios. Segmented high/low speed gain parameters ensure stable low-speed running and fast high-speed dynamic response. The drive automatically stores latest 10 groups of historical fault codes for maintenance inquiry.
7. Applicable Scenarios
This Y01A customized servo drive is specially developed for designated original CNC machine auxiliary feed axes and dedicated precision automation equipment equipped with 0.6kW incremental servo motors supporting dual pulse and analog control. Replacement must use identical full part number CACR-SR06TZ9SM-Y01A.
8. Operation and Routine Maintenance Instructions
Check all power cables, encoder wires and I/O signal wiring to exclude short circuit and loose connection risks before power-on. Avoid arbitrary modification of locked Y01A factory preset parameters without mechanical modification. Ensure 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, inspect cable insulation aging and clean dust accumulated on drive heat sink. Cut off main AC 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 upon continuous fault alarm, then inspect servo motor, connecting cables and mechanical jamming before restarting operation.
9. Basic Troubleshooting
Overheat alarm is mainly caused by blocked heat sink, excessive cabinet ambient temperature or long-term overload operation. Encoder fault alarm usually originates from loose CN2 connector or damaged encoder feedback cable. Overvoltage fault occurs under frequent rapid deceleration with heavy load; install external regenerative braking resistor on P/N terminals to solve the issue.
