8.1.2 Internal Control Supply
Servo drives with code SCA06_______
W2 feature control internal supply. This servo drive does not require
an external control power supply (24 Vdc), that is, it must be used when separate control power supply is not
desired. The servo drive itself generates a 24 Vdc supply and the user can also use it to supply small circuits,
such as digital inputs, for instance. In this case, the connector X5 becomes a 24 Vdc output, with capacity
of 500 mA to be used by the user. It is important to note that this supply has no feedback and, therefore, it is
subject to variations due to the load.
In order to check if the control internal supply is mounted, parameter P00095 must be read.
8.2 ACCESSORIES
The accessories are incorporated to the servo drives in a simple and fast way by the use of the "Plug and Play"
concept by the user. When an electronic accessory is connected to the slots, the control circuit identifies the
model and informs the code of the accessory connected, in P00091, P00092 or P00093.
ATTENTION!
The accessories must be installed or removed with the servo drive de-energized. (Control and power).
The accessories may be purchased separately. They are sold in their own package, containing the component
parts with detailed instructions for installation, operation and programming.
The accessories are connected to the three Slots available on the SCA06, as shown in
Figure 8.2 on page 8-3
.
Each accessory has a fixation / grounding screw that must be tightened after fitting the accessory in the Slot.
