CU250S-2 Control Unit
The Control Unit performs closed-loop control functions for the converter.
The CU250S2 Control Units are designed as standard Control Units for all of the usual applications involving V/f or vector control.
CU250S2 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
• Encoder possible for speed and position control (positioning)

The CU250S2 Control Units can be combined with the following Power Modules:

• PM2402
• 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 138491 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 138491 PL d and Category 3) are optionally available for the CU250S-2 series:

• Safely-Limited Speed (SLS)
  for protection against dangerous movements when a speed limit is exceeded
• 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 converter is switched off. They are therefore not permitted for applications involving pull-through loads such as hoisting gear and unwinders.
