Figure 3-1 System Overview
Above example is of a drive system is supplied from a single or three phase mains connection with a nominal
voltage of 240VAC. Motion control commands are received from a control system, such as a CNC, either in the
form of structured position commands, or as a series of instructions controlling one or more user pre-defined
moves stored locally on the drive.
The following figure provides a block diagram of the drive system. There are three versions of drive system
available corresponding to maximum continuous motor current ratings of 3A, 9A and 15A. The EtherCAT
communications channel is routed between the components within the drive system and the external control
system via CAT5E or CAT6 shielded Ethernet cabling. This communications channel provides interconnectivity
for transmitting and receiving data, such as position commands.
Alternatively, each drive can be controlled through a combination of analogue and digital I/O. Several analogue
inputs and digital inputs/outputs are provided in each drive for user defined signals which may be used for
application specific functions.
