Overview Manuals CUVC Control Role Commissioning Links Feedback Interface Product Applications

Features:

  • CUVC generation: closed-loop and open-loop vector control for MASTERDRIVES
  • Firmware identity: the exact article is specified with V3.4
  • Integrated feedback: HTL encoder and PTC/KTY84 motor-temperature connections
6SE7090-0XX84-0AB0 is the CUVC controller that coordinates vector-control functions inside a SIMOVERT MASTERDRIVES converter.

Its serial interfaces separate local commissioning through a PC or OP1S from drive-network communication over USS.

Analog, digital, encoder, and temperature-sensor connections place the board at the junction between the parameter set and the motor feedback chain.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Platform: the module belongs to SIMOVERT MASTERDRIVES.
  • Controller type: Siemens identifies it as CUVC.
  • Operating methods: closed-loop and open-loop vector control are supported.
  • Firmware: the exact article is associated with Version V3.4.
  • Local connection: RS-232/RS-485 supports a PC or OP1S.
  • Drive network: a separate RS-485 interface supports USS.
  • Parameter recovery: the saved drive set belongs to the installed converter configuration.
  • Migration boundary: another controller generation is not an automatic substitute.
  • Encoder: an HTL unipolar pulse input is provided.
  • Temperature: PTC and KTY84 motor sensors are supported.
  • Digital signals: configurable and dedicated digital channels connect control logic.
  • Analog signals: current or voltage inputs and outputs support process references.
  • SIMOVERT MASTERDRIVES vector control: execute the converter’s closed-loop or open-loop motor-control strategy.
  • HTL encoder feedback: connect the documented unipolar speed-feedback signal.
  • Motor thermal supervision: receive PTC or KTY84 sensor information.
  • Legacy drive maintenance: restore a V3.4 CUVC configuration with its saved parameter set.
Description
At the control core of a SIMOVERT MASTERDRIVES vector-control converter, 6SE7090-0XX84-0AB0 executes closed-loop and open-loop motor control with CUVC firmware V3.4. The exact firmware identity belongs to the requested module and must remain aligned with the installed drive configuration.

Connection resources on 6SE7090-0XX84-0AB0 include an RS-232/RS-485 service interface for a PC or OP1S, an RS-485 USS bus, digital and analog I/O, an HTL unipolar encoder input, and PTC/KTY84 motor-temperature sensing. These onboard functions connect the drive’s feedback, commands, and diagnostics to the existing cabinet design.

Because 6SE7090-0XX84-0AB0 is a discontinued control module, a service exchange should preserve the parameter set and the relationship to the converter power section. A same-size board described with another controller generation or firmware cannot be treated as an automatic replacement.

Technical notes
6SE7090-0XX84-0AB0 is the CUVC vector-control module with firmware V3.4, not a CU2 or generic MASTERDRIVES board. A controller-generation or firmware mismatch can prevent the saved parameter set from running correctly; hold installation until the module identity, converter power section, encoder type, and recoverable drive parameters agree.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Is 6SE7090-0XX84-0AB0 a CU2 control board?
No. Siemens identifies it as a CUVC closed-loop and open-loop vector-control module with firmware V3.4. Use that identity when comparing an offered spare.
What must be saved before changing 6SE7090-0XX84-0AB0?
Keep a recoverable copy of the installed drive parameters and converter configuration. The replacement hardware cannot recreate application tuning, limits, and feedback assignments without that data.
Can 6SE7090-0XX84-0AB0 connect to an OP1S for commissioning?
Yes. The module provides an RS-232/RS-485 interface for a PC or OP1S, separate from the USS RS-485 drive-bus connection.
Which encoder signal is expected by 6SE7090-0XX84-0AB0?
The documented pulse-encoder connection is HTL unipolar. An encoder with a different electrical interface requires the correct adaptation or control hardware rather than a wiring-only assumption.
Can 6SE7090-0XX84-0AB0 monitor a KTY84 motor sensor?
Yes. Siemens lists PTC and KTY84 motor-temperature sensor support. Configure the correct sensor type and preserve the installed terminal assignment during exchange.
What should an RFQ for 6SE7090-0XX84-0AB0 state besides the article number?
Include the CUVC V3.4 identity, installed converter, firmware expectation, encoder type, and whether the parameter backup is available. This prevents a generic MASTERDRIVES board from being quoted as equivalent.
