Stand alone drives are low-cost option
24 February 2017
Motor Technology has introduced a new low-cost option to its range of multi-axis MackDRIVE servo drives from Axor Industries.
The new MackINDY is a range of servo drives and motors designed for single and low-axis-count applications where an economy solution is required. The range includes five servo drive units in two housing sizes up to a power rating of 2,500W.
The 1.5, 2.5 and 3.5 Amp drives are enclosed in a metal casing, providing sturdy mounting, excellent EMC shielding and compact dimensions just 4cm wide. Also available are 5 and 8 Amp units in the same housing with a fan cooling unit that increases the width by only 16mm.
As with the the MackDRIVE range the new MackINDY series operates direct-on-line, without the need for a transformer. To aid cost reduction the MackINDY’s logic circuit is powered by the same single phase 230Vac, 50/60Hz mains supply that energises the power stage. This gives an immediate saving as the 24Vdc power supply for the drive logic is not needed. MackINDY also benefits from integrated in-rush and regen circuits and can also be specified with an internal EMC filter.
To aid quick and simplified commissioning, and further reduce costs, the MackINDY compatible servo motors are supplied as standard with AXOR’s proprietary serial encoder. The serial encoder only requires two cores, making it possible to supply the motor power, brake and encoder signals over one eight core hybrid cable. There are 10 motor options, in four frame sizes, ranging from 0.16 to 5Nm stall torque, with rated speed of 3,000rpm.
The drive offers a number of control modes including, Clock/Direction, Digital Speed Control, Analogue Speed Control, Digital Torque Control, Analogue Torque Control, Electrical Axis (Gearing), CANbus and EtherCAT. Emulated Encoder Output, Safe Torque Off and incremental or absolute Encoder Feedback are also available.
