2. Electrical Ratings
Main power input: 3-phase AC200~230V, allowable fluctuation -15%~+10%, 50/60Hz.Separate single-phase AC200~230V dedicated for control circuit power supply.Rated continuous output:7.6A; 150% overload sustainable for 60s, 300% peak overload limited within 3s.DC bus operating voltage: DC280~320V; P/N terminals reserved for external regenerative braking resistor for frequent heavy-load deceleration.Default command input: ±10VDC analog speed/torque signal; differential pulse position command available after parameter modification.Control scheme: IGBT sine-wave PWM, dual closed-loop of current loop + speed loop.
3. Environmental & Mechanical Parameters
Operation ambient temperature: 0℃~+55℃; storage temperature: -20℃~+70℃.Relative humidity:5%~80%RH, no condensation allowed; protection grade IP20, vertical cabinet rack installation only.Max installation altitude ≤1000m above sea level; anti-vibration 10~55Hz, single amplitude 0.5mm.Net weight approx 2.0kg.
4. Control Performance
Speed adjustment ratio up to 1:5000; full-load steady speed accuracy ≤±0.01%.CN2 port exclusively for incremental encoder feedback (standard 1000~8192P/R TTL incremental encoder).Built-in digital notch filter for mechanical resonance suppression; auto motor parameter identification function available, but Y15 customized gain, acceleration/deceleration parameters are write-protected from factory setting.Three control modes switchable via editable non-locked parameters.
5. Interface Definition
R/S/T: Main three-phase AC power input; U/V/W: Servo motor three-phase power output terminals.CN1: Opto-isolated digital I/O terminal block with 8 input & 6 relay output points, fixed I/O definition customized for Y15 OEM equipment, covering servo enable, forward/reverse limit, E-stop, servo ready and fault alarm output.CN2: Incremental encoder dedicated connector.Onboard RS422 serial port with proprietary Yaskawa protocol for parameter read/write and real-time operation monitoring.Internal dynamic braking circuit for regular regenerative energy absorption; external brake resistor required only for frequent emergency stop heavy-duty operation.
6. Core Features & Protection
Free mode switching between position, speed and torque control; electronic gear ratio for multi-axis synchronous motion.Separated low/high speed gain settings for stable low-speed running and fast dynamic high-speed response.Full protection functions: overcurrent, overvoltage, undervoltage, overheat, encoder fault, motor overload; front 7-segment display shows running status and fault codes directly.Drive saves latest 10 groups of historical fault records for maintenance check.Key parameters under Y15 custom configuration are locked; unauthorized modification is forbidden to avoid machine abnormal operation.
7. Application & Maintenance
Designed as OEM custom servo drive matching standard 0.7kW Yaskawa incremental servo motor for dedicated CNC equipment and fixed automation production lines; replacement requires identical full part number CACR-SR07BB1AM-Y15 only.Power-on pre-check: tighten all power, motor and encoder wiring to eliminate loose connection & short circuit.Cut off main AC supply and wait ≥15min for DC bus capacitor full discharge before opening cover for internal maintenance to prevent electric shock.Periodic maintenance every 3~6 months: clean heatsink dust, retighten terminal screws, inspect cable insulation aging.Immediate power off on continuous alarm; check motor, wiring and mechanical jamming before restarting machine.
8. Basic Troubleshooting
Overheat alarm: clogged heat sink, high cabinet ambient temperature or long-term overload running.Encoder error: loose CN2 connector or damaged encoder feedback cable.Overvoltage alarm under frequent rapid heavy deceleration: mount external brake resistor on P/N terminals.
