Overview
A Power Mate H motion system consists of the Power Mate H control unit, motor(s), servo
amplifiers, I/O, and a machine and its operator's interface (see Figure 1-1).
The Power Mate H unit consists of two parts: the motion control and the machine control. The
motion control translates motion commands into signals, which are then sent to the servo
amplifier. The servo amplifier receives the control signals from the motion control and amplifies
them to the required power level of the motor.
In addition, the motion control provides the link between you, the operator, and the Power Mate H
control. This link is either a CRT/MDI unit or a DPL/MDI programmer. This numerical control
communicates with the other part of the Power Mate, the machine control. The machine control
is a Programmable Logic Controller (PLC) embedded within the Power Mate H.
Within the GE Fanuc Power Mate H, this PLC is considered a Programmable Machine Control
(PMC). It supports the interface between the Power Mate and the machine. For example, the
switches, buttons, and lights (start, stop, etc.) used to run or support the machine are all managed
by the machine control.
