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:

Each Control Unit is available in 3 different versions (for motor
size 71, 80/90, 100/112) for mounting directly on the respective
motor terminal box base.
Safety Integrated functions
The safety function "Safe Torque Off" (STO) (certified according
to IEC 61508 SIL 2 and 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.
