Connection example, external switched-mode power supply on the
ServoOne CM-L charging module
4.9 Busbars for the supply voltages
The
DC link supply
comes from a DC link on the ServoOne CM-A active supply unit
and is connected to the lower busbar (DC Link +/-) in the axis group (charging module,
axis controller, capacitance module etc.). See Figure 4.19.
The
24 V control voltage
is provided to the ServoOne CM-L charging module either
y
By the ServoOne SO CM-S switched-mode power supply (in preparation) (see
section “4.8.1 Control supply with SO CM-S switched-mode power supply” on
page 39).
or
y
By an external switched-mode power supply that is connected to connector X2
on the top of the device (see Section 4.8.2).
The ServoOne SO CM-S switched-mode power supply is mounted on the left
beside the ServoOne CM-L charging module.
The 24 V control voltage is distributed via the upper busbar (+24 V DC and GND, see
Figure 4.17 and Section Figure 4.18) to supply the ServoOne CM system.
Step
Action
Comment
1.
Make sure the supply unit, the switched-mode power supply, the
capacitance module are arranged in a line with all axis control-
lers and they are together in a row.
See mounting instructions.
2.
Always connect first the 24 V control supply!
24 V control supply:
Use the busbar elements supplied with the device for the control
supply. Connect together all (+24 V DC) connections and all
(GND) connections.
Note:
The 24 V busbar fittings are to be
tightened to a tightening torque of
2.1 Nm.
On this topic see section 4.9.1
3.
DC link supply:
Use the busbar elements supplied with the device (accessory
kit) for the busbars for the DC link supply. Connect together all
(DC Link+) connections and all (DC Link–) connections.
Note:
The DC link busbar fittings are to
be tightened to a tightening torque
of 3 Nm.
On this topic see section 4.9.3.
