Wiring the Quad Amplifier System

Quad Amplifier Channel Connections

The Quad Amplifier channels must be connected in a particular order for proper operation. It is essential that the timing of all signals associated with the Quad Amplifier logic board shares the ADC converter clocks for Quad v channels 1-2 and channels 3-4. The ADC clocks are generated from the gate array associated with the axis channel on the PMAC. Each PMAC Gate Array controls four axis channels. Therefore, make sure to connect Quad Amplifier channels 1 and 2 or channels 3 and 4 to the same PMAC channels associated with the same ADC clock Gate array. Faulty operation or even amplifier failure may occur if the user mixes Gate Array channels on either Quad Amplifier channels 1-2 or 3-4. The following chart lists the possible combinations for proper Quad Amplifier operation.

Two Quad Amplifier Example

(A)Can have the following PMAC Axis configuration (GATE 0) 1-2 or 3-4

1-3 or 2-4

1-4 or 2-3

(B)Can have the following PMAC Axis configuration (GATE 1) 5-6 or 7-8

5-7 or 6-8

5-8 or 6-7

Typical Quad Amplifier Setup

A typical Quad Amplifier setup would have all the PMAC axes associated with the corresponding Quad Amplifier channels. For this example, PMAC axes 1, 2, 3 and 4 are connected to the first Quad Amplifier and axes 5, 6, 7, and 8 are connected to the second first Quad Amplifier.
