Four-axis motion controller

The iPOS360x SX motion controller by Technosoft (Switzerland) comes on a 100 mm x 98 mm x 37 mm board. It is capable to drive up to four motors. Connectors for motor, encoder, feedback, and I/O ports are on-board. The drives are connectable to CANopen.

COMPLEX MOTION CONTROL APPLICATIONS often require the design of custom systems. This process is usually expensive and time consuming for the project developers. The introduced 4-axis motion system makes this phase faster and easier, claims the Swiss provider. The motion controller allows plugging in up to four iPOS3602 VX or iPOS3604 VX drives. Two CAN connectors plus an optionally connectable termination resistor realize the interface to the bus-lines. An EIA 232 link offers access to all drives for setup and testing using a PC. Future developments of the motion controller will include also an Ethernet-to-CAN adapter, while a DIN-rail mounting and a metallic cover are already available as options.
The launched board is able to control DC brushed, (rotary or linear) brushless, or stepper motors. Each drive has a built-in motion controller and provides PLC functionality. It can operate as a CiA 402 drive (internationally standardized in IEC 61800-7-201/301) or can be programmed to execute complex motion programs directly at drive level, using the Technosoft Motion Language (TML). TML programming allows each drive to execute motion sequences including setting of various motion modes, I/O signal handling, arithmetic and logic operations, conditional jumps, and calls or data transfers between axes.
The multi-axis controller can be configured that any drive acts as master: the master drive will call each axis to execute and confirm TML functions. The slave drives may also be programmed to periodically send CAN messages to the master drive, so the latter can monitor each task’s progress. If the master is at PC or PLC level, the iPOS360x drives operate as slaves in a similar manner as above, while executing their TML program stored in the local non-volatile memory.
