The OMRON/Delta Tau Mini-PMAC ISA Programmable Multi-Axis Controller delivers compact 2-axis motion control in a half-sized ISA card form factor. Built on a Motorola DSP 56002 Digital Signal Processor, it operates as either an embedded ISA interface within a PC or as a standalone unit via RS-232 serial communication. The controller executes 256 motion programs with asynchronous PLC capability, G-Code processing, linear and circular interpolation, S-curve acceleration profiles, cubic trajectory calculations, and electronic gearing—all with full compatibility to existing PMAC motion and PLC programs.
