Figure 3-1 1.1 System Overview
Above example is of a drive system is supplied from a single phase mains connection with a nominal voltage of
230VAC. 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.
If required, the control of an external mains contactor is provided by a user defined output from the Drive.
The following figure provides a block diagram of the drive system. There are two versions of drive system
available corresponding to maximum continuous motor current ratings of 3A and 9A. The communications
channel is routed between the components within the drive system and the external control system via CAT5E or
CAT6 Ethernet cabling. This communications channel provides interconnectivity for the purpose of transmitting
and receiving data, such as position commands. A number of analog inputs and digital inputs/outputs are
provided in each drive for user defined signals which may be used for application specific functions.
