Panasonic A5 servo sets a high standard
The new Panasonic A5 servo system sets a high performance standard in the power range 50W to 1.5kW, rated torques 0.16 to 4.8Nm. Designed for single phase 230V supply, the drives give ultra-high response and Safe Torque Off as standard. Motors have reduced weight, a peak speed of 6000 r/min and options including brakes and gearboxes. The A5 system is also backward compatible with the current Panasonic A4 system making upgrades easy.
The A5 synchronous servo motors are 10 to 25% lower in weight to previous models. They feature a 20 bit encoder that gives a remarkable 1.04 million pulses/revolution for smoother and more accurate positioning. Maximum speed increases to 6000 r/min and a peak torque capacity 3x rated is available. The internal design with a 10 pole rotor gives speed stability and insignificant cogging torques. Externally the motors are protected to IP67.
Two types of drive are available. The most popular takes analog inputs and has a very high response frequency of 2 kHz giving increased positional accuracy. Safe Torque Off is standard and rated at SIL 2 and PL - d. Setting up the drives is simple with real-time auto-gain tuning plus both manual and automatic filters for notch and damping. The analog and the alternative step/direction drives are designed for 230V AC single phase input.
Panaterm set up software is supplied free with the drives. This has been upgraded and now included service life prediction, a data logging function and motion simulation of performance. Connecting cables for power and feedback between the drives and the motors are available at various lengths with plugs pre-fitted, and these are also IP67 at the motor end to maintain the high level of protection. The motors and brake motors have the option of planetary gearheads with standard or low backlash, and these give rated output speeds between 150 and 1000 r/min in 6 ratios.
The A5 servo system delivers increased performance and safety with compact dimensions and single phase supply. There are seven power levels between 50W and 1.5kW. Further information is available from the Techdrives website www.techdrives.co.uk
