4.14  Commissioning 
You will nd a description of commissioning in the Operation Manual ServoOne CM Axis 
Controller chapter4.
4.15  Connection examples, supply unit
The supply unit can be operated on supply systems with 3 x 230V, 3 x 400 V and 3 x 
480 V. For connection examples, see next page.
NOTE:
A maximum of 8 axis controllers (this corresponds to maximum 24 axes) can 
be connected and operated on one ServoOne CM-P Supply Unit .
NOTE: 
Connections X3 are used only for internal communication between supply unit 
and axis controller.
4.13.2  Specication, relay contact REL Output (X5)
Des. Term. Specication Details
X5
RO02NO = normally open 
contact
Relay contact for low-voltage circuit: 
≤ 250 V AC or ≤ 30 V DC, 1.5 A  
max. each,  
contact freely programmable
Factory setting = Operation of main 
contactor
NOTE:
For switching inductive loads (e.g. auxiliary contactors) on X5, we recommend 
the usage of suppressors (AC-operated contactors) or free-wheeling diodes 
(DC-operated contactors) on their control coils.
4.13.3  Specication, connection "State" (X6)
Des. Term. Specication Details
X6
RO01NC = normally closed 
contact
RO01CO = changeover 
contact
RO01NO = normally open 
contact
Signal relay contact for PELV circuit: 
 ≤ 25 V AC or ≤ 30 V DC, 0.5 A max. 
each (only ohmic load), 
contact freely programmable
Factory setting = Active on error
X6
TP00 = test pulse signal 
00
TP01 = test pulse signal 
01
GND = reference ground
Signal driver outputs for 
internal usage for short-
circuit and cross-circuit 
checks on the wiring to 
the safe inputs on the axis 
controllers
