CU240M Control Units Siemens

Обзор



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:

Safety Integrated functions

The safety function "Safe Torque Off" (STO 1)) (certified according 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.

1) Available for firmware version V4.7 or higher
