Servo drive includes simulated plc

. The XVy from SIEI includes what the company styles the 'MDplc'. This can be used to control both the drive and external devices, such as switches, monitors, alarms and displays, thus acting as a local systems controller. Programming can be by Ladder diagram, machine code or IEC1131 block diagram languages, the choice being selectable on start up. A special Windows software tool called E@sydrive is used to access all standard set up parameters as well as access to the MDplc. Standard communications are CANOpen, ModBus and deviceNET, with Profibus-DP available as an option. The standard unit also supports SIEI's proprietary FastLink, a six wire or fibre optic master slave configurator allowing connection of up to seven slave drives. These can be daisy chained if desired, so each slave is master of the next slave in the chain. The controller can be configured to operate in modes that include: torque, speed, position, and electric line shaft. Features include selection of resolver or encoder feedback device to allow maximum flexibility when matching the drive to motor specifications. Plug in expansion boards are available for further encoders and devices and I/O expansion. The drive has been proven on various applications in its native Italy. There include: a rotating drill, a positioner for a high speed bottle machine, printing, packaging and winding and unwinding machines plus leading edge applications in engineering research.
