2.Electrical Specifications
Main power input is three-phase AC200V~230V, voltage fluctuation range -15%~+10%, rated 50/60Hz; control power adopts independent single-phase AC200V~230V separated power supply.Continuous output rated 7.6A; 150% overload sustainable for 60 seconds, peak 300% overload limited within maximum 3 seconds; DC bus working voltage DC280V~320V, P/N terminals reserved for external regenerative brake resistor for frequent deceleration heavy load condition.Default supports ±10VDC analog speed/torque command plus differential pulse position dual input owing to S coding definition; control topology is IGBT sine-wave PWM modulation with double closed-loop of current and speed control loop.
3.Environment & Mechanical Parameters
Permitted working ambient temperature 0℃~+55℃, storage temperature from -20℃ to +70℃; operating relative humidity 5%~80%RH with no dew condensation allowed.Protection grade IP20 designed for indoor vertical cabinet installation; max installation altitude below 1000 meters above sea level; anti-vibration capability 10~55Hz with 0.5mm single amplitude; net weight approx 1.98kg.
4.Control Performance & Interface Description
Speed adjustment ratio up to 1:5000, full-load steady speed precision within ±0.01% tolerance.CN1 connector is optically isolated digital I/O terminal including 8 input points and 6 relay output terminals for servo enable, positive/negative travel limit, emergency stop, servo ready and fault alarm signal wiring; CN2 is exclusive incremental encoder feedback port compatible with 1000~8192P/R TTL incremental encoders.Onboard RS422 serial port follows Yaskawa proprietary communication protocol for parameter reading/writing and real-time operating status monitoring; built-in internal dynamic braking circuit covers regular regenerative energy dissipation during deceleration; external brake resistor only required for high-frequency emergency stop heavy-duty working scene.
5.Functions & Full Protection Items
Three control modes can be freely switched via parameter modification, built-in electronic gear ratio function to realize multi-axis synchronous motion; separated low-speed and high-speed gain parameters optimize low-speed smooth operation and high-speed dynamic response separately.Complete protection functions include overcurrent, overvoltage, undervoltage, overheat, encoder breakdown and motor overload protection; front panel seven-segment digital display directly shows running status and fault alarm codes, the drive automatically saves latest ten groups of historical fault data for maintenance troubleshooting.
6.Application & Maintenance Instruction
This 0.7kW customized BZ variant servo drive matches Yaskawa standard 0.7kW incremental servo motor, widely used on precision CNC lathe, automatic feeding equipment and general industrial automation positioning machinery.Before power-on, check tightness of main power cable, motor U/V/W wiring and encoder cable to avoid loose contact or short-circuit fault; cut off AC input power and wait no less than 15 minutes for internal DC bus capacitor full discharge before opening cover for overhaul to prevent electric shock danger.Periodic maintenance every three to six months mainly includes radiator dust cleaning and terminal screw retightening; cut off power supply immediately once continuous fault alarm occurs, inspect motor, wiring and mechanical stuck issue before restarting equipment.
