8.3 System installation
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 chap-
ter
11. DIMENSIONS , that shows all the necessary values.
 Unpack motors, drive modules, 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 servo drive 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.
 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).
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 drive 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 module 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 out-
puts.
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 (SER-
COS) or cable (CAN)
accordingly. See the section “SERCOS con-
nection” 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.
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 refer-
ence is PF 23A or older. With newer references, 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.
