Description
1. Model Code Explanation
CACR stands for Yaskawa classic VS800 full digital AC Servopack series dedicated for CNC feed axis and automation equipment control. SR means three-control-mode servo amplifier with switchable speed, torque and position control via internal parameter setup. 07 matches 0.7kW rated servo motor, with continuous rated output current of 7.6A RMS. The first B refers to standard rack-mounted hardware structure for cabinet installation. Second B represents revised mainboard circuit design for BB customized hardware version. 1 denotes Version 1 base firmware platform. A is defined for analog ±10VDC command input priority configuration. M indicates standard general version without OEM locked parameters, all internal parameters can be freely reset to factory default setting, different from Y-suffix customized locked models.
2. Electrical Ratings
Main power supply is three-phase AC200V~230V with allowable voltage fluctuation from -15% to +10%, rated frequency 50Hz/60Hz. Independent single-phase AC200V~230V input is prepared for separated control circuit power source. Continuous output current is 7.6A; 150% overload operation is available for 60 seconds, while 300% peak overload is limited within maximum 3 seconds. DC bus voltage ranges DC280V~320V, P and N spare terminals are reserved for external regenerative braking resistor connection under frequent deceleration heavy load condition. This model mainly receives ±10VDC analog speed/torque command, and supports optional differential pulse position command after related parameter modification. It adopts IGBT sine-wave PWM modulation with double closed-loop of current loop and speed loop control.
3. Environmental & Mechanical Data
Permitted operating ambient temperature is 0℃~+55℃, storage temperature from -20℃ to +70℃, working relative humidity 5%~80%RH without dew condensation. Protection grade is IP20 for indoor cabinet vertical rack installation; max applicable installation altitude is below 1000 meters above sea level. The unit withstands 10~55Hz vibration with 0.5mm single amplitude, net weight approx 1.95kg.
4. Control Performance & Interface
Speed adjustment ratio reaches 1:5000 with full load steady speed accuracy within ±0.01%. CN2 connector is exclusive for incremental encoder feedback wiring, compatible with 1000~8192P/R standard incremental encoders. CN1 is optically isolated digital I/O terminal block including 8 input points and 6 relay output points, covering servo enable, positive/negative limit, emergency stop, servo ready and fault alarm signal functions. Built-in RS422 serial communication port applies Yaskawa dedicated protocol for parameter read/write and real-time running status monitoring. Built-in dynamic braking circuit handles conventional regenerative energy during deceleration; external brake resistor is only needed for high-frequency emergency stop working conditions.
5. Key Features & Protection Functions
Three control modes can be switched freely by parameter setting, electronic gear ratio function supports multi-axis synchronous movement. Separate low-speed and high-speed gain parameters optimize low-speed smooth running and high-speed dynamic response. Multiple built-in protection functions include overcurrent, overvoltage, undervoltage, overheat, encoder fault and motor overload protection; the 7-segment digital display on front panel shows real-time operation status and corresponding fault alarm codes directly. The drive automatically stores latest 10 groups of historical fault records for maintenance troubleshooting.
6. Application & Maintenance
It is standard universal 0.7kW servo drive widely matched with corresponding Yaskawa standard 0.7kW incremental servo motors for ordinary CNC equipment, automatic feeding machinery and general industrial automation positioning equipment. Before power-on, inspect tightness of power cable, motor wiring and encoder cable to avoid short-circuit or loose contact. Cut off main AC power and wait over 15 minutes for full capacitor discharge before internal disassembly to prevent electric shock risk. Regular maintenance every 3~6 months includes cleaning radiator dust and fastening terminal screws; stop operation immediately once continuous alarm appears and check motor, wiring and mechanical jamming issue before restarting equipment.
