SINAMICS G120D distributed inverters
0.75 kW to 7.5 kW (1 hp to 10 hp)
CU240D-2 and CU250D-2 Control Units
■
Overview
The Control Unit performs closed-loop control functions for the
inverter. In addition to the closed-loop control, it has additional
functions that can be adapted to the particular application
through parameterization. The CU240D-2 Control Units super-
sede the CU240D Control Units, whereby both versions can be
operated with PM250D Power Modules.
CU250D-2 Control Units can be used to implement applications
with positioning requirements in the drive. This expansion opens
up their use in lifting, swiveling, traversing or rotating applica-
tions. The positioning functionality is comparable to that of
SINAMICS S110 servo drives.
Two points must be noted in this context:
•
Vector control (VC) and sensorless vector control (SLVC) are
possible (but not servo control)
•
Positioning using one encoder (HTL/SSI) or using two en-
coders simultaneously (HTL and SSI)
Control Units are available in different versions:
•
CU240D-2 DP
•
CU240D-2 DP-F
•
CU240D-2 PN
•
CU240D-2 PN-F
•
CU240D-2 PN-F PP (Push Pull)
•
CU240D-2 PN-F FO (fiber optic)
•
CU250D-2 DP-F
•
CU250D-2 PN-F
•
CU250D-2 PN-F PP (Push Pull)
•
CU250D-2 PN-F FO (fiber optic)
The Push Pull version comprises an alternative connection
method for the 24 V DC supply voltage and the PN communi-
cation.
