Functionality of the SIMATIC Drive Controller

SIMATIC Drive Controller

The SIMATIC Drive Controller is a drive-based controller in the SIMATIC S7-1500 range.

A SIMATIC Drive Controller combines the following functionalities in a SINAMICS S120 Booksize Compact housing:

Fail-safe SIMATIC S7-1500 technology CPU with integrated technology I/Os

SINAMICS S120 drive control

The two components are referred to as "CPU" and "SINAMICS Integrated" in this documentation.

The integrated SINAMICS S120 drive control is based on a CU320-2 Control Unit. It can control

a maximum of 6 servo drives,

a maximum of 6 drives with vector control, or

a maximum of 12 drives with U/f control

Fail-safe technology CPUs are available in two performance classes. Safety Integrated on the CPU side and drive side allows use in fail-safe applications.

The SIMATIC Drive Controller supports PROFINET and PROFIBUS DP communication.

Drive Controller-specific hardware properties

As a component of the SINAMICS S120 drive system, the configuration conditions and rules of SINAMICS S120 apply to the SIMATIC Drive Controller.

Drive Controller-specific properties of the CPU

The SIMATIC Drive Controller is optimized for automation solutions with motion control in which SINAMICS S120 high-performance converters are used.

With its extensive field bus interfaces, the SIMATIC Drive Controller is ideal for modular machine concepts.

Service functions

The SIMATIC Drive Controller does not have an integrated display. You can alternatively run service functions over the integrated Web server, for example. You can save the service data to the SIMATIC memory card using the FUNCT button.

S7-1500 I/O

The SIMATIC Drive Controller has no S7-1500 backplane bus. You can connect S7-1500 I/O modules using the ET 200MP distributed I/O system. Note that CM/CP communication modules for PROFINET/PROFIBUS in particular cannot be used in the ET 200MP distributed I/O system. Only communication modules for point-to-point connection (CM PtP) can be used. Alternatively, other I/O systems are available for installation in the control cabinet (e.g. ET 200SP) or for cabinet-free installation (e.g. ET 200pro, ET 200AL and ET 200eco PN).

Time-based IO

The function blocks for the use of time-based IO (TIO instructions) are not supported by the digital inputs/outputs of the X142 interface. Recommendation: Use the measuring input, output cam or cam track technology objects for the timer DI/DQ.

Device replacement

The SIMATIC Drive Controller supports replacement of the SIMATIC Drive Controller CPU with the modular SIMATIC S7-1500 CPUs. Replacement with controllers of other designs (e.g. ET 200SP, ET 200pro) is not possible.

Drive Controller-specific properties of SINAMICS Integrated

The drive control integrated in the SIMATIC Drive Controller supports only functions that are relevant in the control context (i.e. functional subset of SINAMICS S120 CU320-2 functions). For example, the Drive Control Chart (DCC) and basic positioner (EPOS) functions are not supported by SINAMICS Integrated.

A complete overview of the functional subset compared with the S7-1500 automation system can be found in the S7-1500 Drive Controller system manual.

Device replacement

An exchange of devices between SINAMICS Integrated and SINAMICS S120 CU320-2 is not possible.

Copying and pasting of individual drive objects from SINAMICS Integrated to SINAMICS S120 CU320-2 (and vice versa) is not possible with V16.
