The PMAC PCI Lite 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, although it can have only four channels of on-board axis interface circuitry.
The PMAC PCI Lite is a full-sized PCI-bus expansion card. While capable of PCI bus communications, with or without the optional dual-ported RAM, it does not need to be inserted into a PCI expansion slot. Communications can be done through an RS232 or RS422 serial port. Standalone operation is possible. |
