More compact servo drives

A split core structure and new housing means Panasonic has been able to reduce the length by 30% and weight by up to 10%. The encoder design too has been made more compact.

Other features include:

•  Modbus RTU interface – open serial communication protocol (RS232 or RS485)

•  High-resolution encoder – the 20-bit MINAS A5 encoder (1048576 pulses per revolution) has been upgraded to 23 bit (8388608 ppr).

•  Advanced controller settings: the new servo motors come with a faster velocity response (3.2kHz), which means that the driver can react even faster.  In addition, micro vibrations have been reduced due to an improved reaction of the current regulation and linearity.

•  Lower torque variation

•  Improved vibration suppression during standstill under a static load

•  Improved suppression of load variations

•  Improved oil seal – offers triple protection against dust and oil due to triple-lip oil seal.

The same cables and connectors used for the A5 series can be used for the A6 series. It is not necessary to store additional parts. If machines need to be modified or exchanged, connected devices do not have to be changed.
