Application Notes
1 Scope
These Application Notes are a guide to applying the
G122-829-001 P-I Servoamplifier. These Application Notes
can be used to:
Determine the closed loop structure for your application.
Select the G122-829-001 for your application. Refer also
to data sheet G122-829.
Use these Application Notes to determine your system
configuration.
Draw your wiring diagram.
Install and commission your system.
Aspects, such as hydraulic design, actuator selection, feedback
transducer selection, performance estimation, etc. are not
covered by these Application Notes. The G122-202 Application
Notes (part no C31015) cover some of these aspects. Moog
Application Engineers can provide more detailed assistance,
if required.
2 Description
The G122-829-001 is a general purpose, user configurable,
P-I servoamplifier. Selector switches inside the amplifier enable
either proportional control, integral control, or both to be
selected. Many aspects of the amplifier's characteristics can be
adjusted with front panel pots or selected with internal
switches. This enables one amplifier to be used in many
different applications. Refer also to data sheet G122-829.
3 Installation
3.1 Placement
A horizontal DIN rail, mounted on the vertical rear surface
of an industrial steel enclosure, is the intended method of
mounting. The rail release clip of the G122-829-001 should
face down, so the front panel and terminal identifications
are readable and so the internal electronics receive a cooling
airflow.
An important consideration for the placement of the module is
electro magnetic interference (EMI) from other equipment in
the enclosure. For instance, VF and AC servo drives can
produce high levels of EMI. Always check the EMC compliance
of other equipment before placing the G122-829-001 close by.
3.2 Cooling
Vents in the top and bottom sides of the G122-829-001 case
provide cooling for the electronics inside. These vents should
be left clear. It is important to ensure that equipment below
does not produce hot exhaust air that heats up the G122-829.
