The programmable step motor driver with Fieldbus allow to easily manage multiple axis using one only connection to the master control device.
The applications with great number of motors take huge advantages from the use of fieldbus as it reduces wiring with economic benefits and realibility. This technology also allows to place the drives close to the motors reducing the space needed in the cabinet.
Some products are also able to execute an internal program and this makes them ideal to realize applications with distributed intelligence. The programmability of the drive is also useful to reduce the traffic of messages on the fieldbus and locally manage the operations in real time, such as stopping or starting of a movement in correspondence with a signal coming from a photocell or the update of the rotation speed according to an analog external quantity.
The range of Fieldbus drives also includes models with USB interface ideal to realize the PC-based applications. The drivers supplied with the product allow to use it both in Windows (32bit or 64bit) and Linux platforms.
