Delta Tau: Programmable Multi-Axis Controller (PMAC-PC)
The PMAC PC is a member of the PMAC family of boards optimized for interface to traditional Servo drives with single analog inputs representing velocity or torque commands. Its software is capable of eight axes of control. It can have up to four or eight channels of on-board axis interface circuitry.
The PMAC PC is a full-sized ISA-bus expansion card, with a small piggyback board containing the CPU board. This piggyback board occupies part of the next slot, but ½-sized boards (such as the Option 2 Dual-Ported RAM board) are permitted in this next slot. While the PMAC PC is capable of ISA bus communications, with or without the optional dual-ported RAM, it does not need to be inserted into an ISA expansion slot. Communications can be done through an RS-232 or RS-422 serial port. Standalone operation is also possible.
