The Parker PSD series has been developed specifically to be compatible with all geographic areas and is claimed to be the most compact multi axis servo drive available today.
The single cable DSL feedback system is claimed to provide lower cabling and installation cost. The encoder feedback between drive and motor is fully integrated into the motor power cable, and thus a separate feedback cable is not needed any longer.
The servo drives are available with different power rating and form factors. At present these are the PSD-S, a standalone version which can be connected directly to the mains supply; and PSD-M, a multi-axis system where each power module can supply up to three servo motors.
The latter's base configuration consists of a common DC bus supply and multiple PSD-M modules connected through DC bus bars. The modules are available as one-, two- or three-axis versions combined in a single housing, which makes the system compact and flexible. The PSD-M is particularly suitable for centralised automation systems, such as those found in many packaging machines where large numbers of drives are often required.
The drives are available with power stages in a range from 2.0 to 30A and offer four digital inputs and two digital outputs per axis, with connection via fast and simple direct plug-in technology. There is a removable SD card and, on the multi axes system, a common DC bus connection for energy exchange between drives. There is also customisation potential, and a functional safety option is available to meet machinery directives.
