Panasonic Electric Works introduced its newest digital AC servo drive systems, the A4 series. The A4 series, digital AC servo drives have a slim profile/power ratio, carry global certification such as UL and CE, and cover a power range from 50W to 5.0kW. Along with a velocity response (bandwidth) of 1kHz, the drives offer a high-functionality Real-Time Auto-Gain Tuning, to react to even variations of load inertia. The Real-Time Auto-Gain Tuning gives the user the ability to select the stiffness of the machines from low to high with a combination of an adaptive filter, 2-channel notch filters, damping control and supports vertical axis applications. Setup can be performed by keypad or with the intuitive setup software, PANATERM. With "Position", "Velocity' and "Torque" command control modes, the A4 series are truly multi-functional. In "Position" control mode, the drives will sccept up to 2Mpps of pulse input and can be used with the Panasonic PLCs for outstanding performances. The A4 series motors have metric mounting flanges and shafts dimensions, and are capable to produce speed up to 5,000 rpm. IP65 rating is stnadard on all the motors and any motor can be ordered with an optional oil seal and holding brake. The use of serial encoders reduces the numbers of wire from 11 to 5 for the standard incremental encoder (2,500 pulse/rev) and from 14 to 7 for the optional 17-bit absolute encoder. The combination of the newly redesigned A4 series motors and the A4 series digital AC servo drives produces a simple, easy to use motion control systems for a large variety of motion control applications, such as packaing and assembly machinery, conveyor belts, CNC machines and any other applications, which require accurate positioning along with high speed and torque.
