SINAMICS G110M distributed inverters
0.37 kW to 4 kW (0.5 hp to 5 hp)
CU240M Control Units
■
Overview
The Control Unit performs closed-loop control functions for the
inverter. In addition to the primary closed-loop control function,
it has many additional functions that can be adapted to the
particular application through parameterization.
The Control Units are available in two versions for connection to
400 V 3 AC and 24 V DC – screw-type or plug-in. The version in
USS fieldbus communication is only available as screw-type.
The differences between the screw-type and plug-in versions
are presented in the following pictures:

Several Control Units are available in different versions:
Safety Integrated functions
The safety function "Safe Torque Off" (STO
1)
) (certified accord-
ing to IEC 61508 SIL 2 and EN ISO 13849-1 PL d and
Category 3) is already integrated into the basic versions of
the CU240M series (CU240M, CU240M DP and CU240M PN).
It prevents active movement of the drive. It can be activated
either over PROFIsafe or over the safety input.
Existing systems in particular can be simply updated with safety
technology without the need to change the motor or mechanical
system.
