CU230P‑2 Control Units

 

The Control Unit performs closed-loop control functions for the inverter.

The CU230P-2 Control Units are designed for drives with integrated technological functions for pump, fan and compressor applications.
The I/O interface, the fieldbus interfaces and the additional software functions optimally support these applications. The integration of technological functions is a significant differentiating feature to the other Control Units of the SINAMICS G120 drive family.

The CU230P-2 Control Units can be operated with the following Power Modules:
- PM240‑2
- PM240

Note:
The CU230P‑2 is the Control Unit for SINAMICS G120P and SINAMICS G120P Cabinet for pumps, fans and compressors.
Please refer to Catalog D 35 for more information.

Note:
Shield plates and shield connection kits are available. These can be used in the wiring installation for the Control Units and Power Modules to ensure that it complies with EMC guidelines.

For more information about shield connection kits and shield plates for Control Units and Power Modules, please refer to section "Supplementary system components".

Control Unit CU240E‑2

The Control Unit performs closed-loop control functions for the inverter.

The CU240E‑2 Control Unit is designed as standard Control Unit for all of the usual applications involving U/f or vector control.
- CU240E-2 series with standard I/O quantity structure and integrated safety technology

The CU240E‑2 Control Unit can be combined with the following Power Modules:
- PM240‑2

- PM240

- PM250

Note:
Shield plates and shield connection kits are available. These can be used in the wiring installation for the Control Units and Power

Modules to ensure that it complies with EMC guidelines.

For more information about shield connection kits and shield plates for Control Units and Power Modules, please refer to section "Supplementary system components".

Safety Integrated functions
The safety function "Safe Torque Off" (STO) (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 CU240E‑2 series (CU240E‑2, CU240E‑2 DP, CU240E‑2 PN).

With the fail-safe variants of the CU240E-2 series (CU240E‑2 F, CU240E‑2 DP-F, CU240E‑2 PN-F), the fail-safe SINAMICS G120 inverter provides five safety functions which are certified according to IEC 61508 SIL 2 and EN ISO 13849‑1 PL d and Category 3:

- Safe Torque Off (STO)
to protect against active movement of the drive

- Safe Stop 1 (SS1)
for continuous monitoring of a safe braking ramp

- Safely Limited Speed (SLS)
for protection against dangerous movements when a speed limit is exceeded (the CU240E‑2 DP‑F Control Unit has up to 4 selectable SLS limit values)

- Safe Direction (SDI)
This function ensures that the drive can only rotate in the selected direction.

- Safe Speed Monitor (SSM)
This function signals if a drive operates below a specific speed/feed velocity (only CU240E‑2 DP‑F / CU240E‑2 PN‑F with PROFIsafe).

These functions can be activated by means of PROFIsafe or via the safety inputs.

None of the safety functions require a motor encoder and they are thus much cheaper and easier to implement. Existing systems in particular can be simply updated with safety technology without the need to change the motor or mechanical system.

The Safe Torque Off (STO) function can be used without restriction for all applications. The SS1, SLS, SDI and SSM functions are only permissible for applications where the load can never accelerate when the inverter is switched off. They are therefore not permitted for applications involving pull-through loads such as hoisting gear and unwinders.

CU250S‑2 Control Units

CU250S-2 Control Unit


The Control Unit performs closed-loop control functions for the inverter.

The CU250S‑2 Control Units are designed as standard Control Units for all of the usual applications involving V/f or vector control.

CU250S‑2 Control Units can be used to implement all common applications involving V/f or vector control as well as applications for drives with positioning requirements. This expansion allows them to be used in lifting, swiveling, traversing or rotating applications. The positioning functionality is comparable with SINAMICS S110 servo drives.

Two points must be noted here:
- Vector control (VC) and sensorless vector control (SLVC) are possible

- Positioning possible via one encoder or in parallel using two encoders

The CU250S‑2 Control Units can be combined with the following Power Modules:
- PM240‑2
- PM240
- PM250

Note:
Shield plates and shield connection kits are available for use in the wiring installation of Control Units and Power Modules to ensure that it complies with EMC guidelines.

For more information about shield connection kits and shield plates for Control Units and Power Modules, please refer to section "Supplementary system components".

Safety Integrated functions
The following Safety Integrated Basic Functions (certified according to IEC 61508 SIL 2 and EN ISO 13849‑1 PL d and Category 3) are integrated as standard in the CU250S-2 series:

- Safe Torque Off (STO)
to protect against active movement of the drive

- Safe Stop 1 (SS1)
for continuous monitoring of a safe braking ramp

- Safe Brake Control (SBC) is used to safely control a holding
brake

The following Safety Integrated Extended Functions (certified according to IEC 61508 SIL 2 and EN ISO 13849‑1 PL d and Category 3) are optionally available for the CU250S-2 series:
- Safely Limited Speed (SLS)
for protection against dangerous movements on exceeding a speed limit

- Safe Direction (SDI)
This function ensures that the drive can only rotate in the selected direction.
- Safe Speed Monitor (SSM)
This function signals if a drive operates below a specific speed/feed velocity.

These functions can be activated by means of PROFIsafe or via the safety inputs.

None of the safety functions require a motor encoder and they are thus much cheaper and easier to implement. Existing systems in particular can be simply updated with safety technology without the need to change the motor or mechanical system.

The Safe Torque Off (STO) function can be used without restriction for all applications. The SS1, SLS, SDI and SSM functions are only permissible for applications where the load can never accelerate when the inverter is switched off. They are therefore not permitted for applications involving pull-through loads such as hoisting gear and unwinders.
