Features: • BLSi7080 can be programmed for stand-alone operation with the easy to use Si™ Programmer Windows software (software and programming cable included). • BLSi7080 can be operated in real time from a host PC or PLC using the Si™ Command Language (SCL), via RS-232. • Direct 120/240 volt, 50/60 Hz AC input. No external Power Supply needed. • Continuous current of 7A, peak current to 14A. • Speeds to 6,000 rpm. Motor and load dependent. • 20 kHz precision PWM amplifier. • Pluggable screw terminal connectors for AC power, motor phases, communications and I/O. • Pluggable, industry standard D connector for encoder and commutation signals. • Optically isolated RS-232, RS-485 or RS-422 communications. • Optically isolated I/O. • Internal regeneration clamp circuit. No external components needed. Options: • Five custom matched Applied Motion Alpha series brushless servomotors. • Standard or custom length extension cables. • Complete system configuration ordering. • SiNet™ Hub compatible for networking with all Applied Motion intelligent stepper and servo drives to create full machine control. • Two custom configured operator interfaces are available the MMI-01 and backlit MMI-02. MMI can be used to display messages or by the operator to enter command data such as move speeds, distance or loop counts. |
Description: The BLSi7080 programmable servo drive include a motion controller, digital PID position loop, amplifier and 80 volt power supply. These features make it suitable for a wide range of motion applications using either brush or brushless motors. The BLSi7080 includes Applied Motion's easy to use Si™ Programmer Windows software for the rapid development of stand-alone motion control programs. The BLSi7080 can also be commanded in real time from a host PC or PLC, using the Si™ Command Language (SCL). For multi-axis applications, up to eight BLSi7080 drives can be networked using the SiNet™ Hub. Up to 32 drives can be connected using the built-in RS-485 interface. Networking also allows the BLSi7080 to be mixed with other Si™ drive models, stepper and servo. The BLSi7080 includes 8 programmable inputs for triggering, branching, position sensing and end of travel detection. 3 programmable outputs can send signals to other electronic devices and activate relays. Tuning the PID loop of either model is easy with our Quick Tuner software, which features a built-in oscilloscope. Software selection of encoder line count and commutation sequence allows the motor to be configured without swapping wires.
