Preparation
After knowing the system's environment, the step before installing the DDS
system is the following:
 Preparing the mounting fixtures inside the electrical cabinet. See chapter
11. DIMENSIONS , that shows all the necessary values.
 Unpack motors, drives, auxiliary modules and other elements that make
up the DDS system.
 Mount each of the motors on the machine.
 Install all the modules making up the DDS system in the electrical
cabinet.
Procedure
Follow these steps for a complete system installation:
 Mount all the system modules in the electrical cabinet.
 Mount the mains filter · MAIN FILTER · .
 Connect electrically and mechanically all the modules with each other.
1. Connect the plates on the power bus located at the bottom of each
module (under the cover).
DANGER. Remember that an auxiliary power supply is already integrated
into the XPS and RPS power supplies. If it is necessary to also install an APS-
24 auxiliary power supply module for any reason together with one of these
power supplies, NEVER connect APS-24 modules whose version is PF
23A or older. With newer versions, you may connect the APS-24 module to
the power DC bus of the DDS system regardless of the main power supply
it may come with.
2. Connect the ground bars at the top and make the connection next to
the ground terminal.
3. Connect the internal bus.
4. Connect the external Ballast resistor accordingly. See the section
"heat dissipation" in this chapter.
 Connection with motors and the CNC.
1. Cable from mains to the DDS system through the filter.
2. Power cable from each motor to each drive.
3. Feedback cable from each motor to each drive.
4. Circuit for the control of the brake (if applicable).
5. Power for the 24 V DC auxiliary power supply from mains (APS-24,
PS-25B4, XPS or RPS).
6. Power the control circuits of each drive with 24 V DC.
 Control and communications signals.
1. Encoder simulator cable from each drive to the CNC (if applicable).
2. Analog velocity command voltages from the CNC to each drive.
See the section "analog command" in this chapter .
3. Connection of the control signals of the modules, inputs and outputs.
4. SERCOS ring or CAN bus connection accordingly.
See the section "SERCOS connection" or "CAN connection" in this
chapter.
5. Identify each system drive with its rotary switch.
6. Module connection with the CNC through a fiber optic ring
(SERCOS) or cable (CAN) accordingly. See the section "SERCOS
connection" or "CAN connection" in this chapter.
7. Module connection with an ESA panel via RS-422 if applicable. See
the section "RS-422 serial line connection" in this chapter.
