The following table shows the values for gap, tightening torque, sections of
the screws and other data of the plug-in connector for X2.
A door closes an enclosure that contains a DDS system with an RPS power
supply. The 24 V DC supplied at pin 1 of connector X2 may be taken to one
end of the door opening/closing switch and connect the other end to pin 4
“
PWM ENABLE” of control connector X6. When the door is closed, 24 V DC
are applied to pin 4 “PWM ENABLE” hence letting the system run. When the
door opens, the switch opens and voltage is no longer applied to pin 4 of X6
hence opening the integrated safety relay. The system stops.
NOTE. Do not take this example as a real application, but just as an
approach to the functionality of the “
PWM ENABLE”.
X3 connector
The main integrated contactor “LINE CONTACT” (N.O., Normally Open) is
closed through connector X3.
The status of the contactor will be acknowledged through pins 1 and 2 of this
connector and the CNC, PLC, control panel, etc. will confirm that the
integrated contactor has actually closed.

INFORMATION. In cases of micro-surges or total loss of mains power, this
module guarantees stable and maintained 24 V DC while the motors are
being stopped. This is an absolute must in order to comply with the EC
requirement for the machine.
Example regarding the 24 V DC of connector X2
MANDATORY. Pins 3 and 4 MUST BE short-circuited to close the internal
contactor of the power supply and let the system run. Hence, get a 1 mm²
cable and jumper NS1 (pin 3) and NS2 (pin 4) externally to close the main
internal contactor. Remember that these pins do not come short-circuited
from the factory and if they are not short-circuited by the user, the DC BUS
will not be charged.
