Receiving and Handling
Inspection upon Receipt
Upon the receipt of equipment, inspect all merchandise for any indication of damage that may have
incurred during shipping and handling. If any items are damaged, do not accept them until the freight
carrier makes an appropriate notation on the freight bill or express receipt. Claims for loss or damage in
shipping must be taken up with the shipping or freight carrier.
Storage Requirements
Store the equipment in a clean environment until ready for installation. It is advisable to leave the
equipment in its original shipping container until ready to use.
Prior to Installation
Each amplifier is carefully checked before shipping. However, upon receipt, make sure that the Quad
Amplifier received corresponds to, or is properly rated for, the voltage and current of motors that are to be
driven. The Quad Amplifier identification tag specifies the electrical ratings of each axis.
CAUTION:
It is important to double check the part number and serial number against the order
form to avoid damage that may be caused by the misapplication of the digital Quad
Amplifier.
Equipment Required
The Quad Amplifier is installed in conjunction with other Delta Tau Data System components to form a
Quad Amplifier System. The following table identifies the equipment which, when installed and
connected together, constitute a typical Quad Amplifier System. Figure 2 shows the interconnection of
the Quad Amplifier System components.
Component Quantity Description
Quad Amplifier 1 Delta Tau 4-Axis Digital Quad Amplifier
PMAC2 or PMAC2 Lite 1 Delta Tau 4-Axis Controller Card
Acc-8F 1 - 2 Delta Tau Digital Interface Board (one 16-inch cable is
included with each Acc-8F to connect with the PMAC2)
Acc-8F, Opt 5 1 to 4 36-inch Delta Tau PWM input cables
Motors 1 to 4 Customer-supplied AC induction or brushless servo motors
Installation Considerations and Options
The design of the Delta Tau Quad Amplifier allows for either internal chassis mounting or external
chassis mounting. In either case, the unit can be mounted either horizontally or vertically. Vertically is
the preferred mounting.
Option 3, 3A and 3B (External Mount)
Options 3, 3A and 3B are designed for external chassis mounting. These are used when the Quad Amplifier
heat sink (cooling fans and internal shunt resistor included with Options 3 and 3A) is externally mounted
through an electrical cabinet opening or when the Quad Amplifier heat sink is mounted in an air plenum
(Option 3B) with external, customer supplied forced air and optional external shunt resistors (Acc 4).
Option 4 and 4A (Internal Mount)
Options 4 and 4A provide mounting feet and self-contained cooling fans. These are used when the Quad
Amplifier is to be mounted to a panel, in a Hoffman style electrical box. Consider the following, before
the Quad Amplifier is installed in a cabinet:
