CV30
Salicru's Controlvit CV30 variable frequency drive series stands out for its design, reliability, compact size and ease of use. The high quality of its components, advanced features and versatility make it the ideal variable frequency drive for the actuation of low-power motors (0.4 kW to 7.5 kW) in the vast majority of applications, being available for both single-phase (230 VAC) and three-phase (400 VAC and 230 VAC) supply voltages.
Its advanced sensorless vector control, which has two different algorithms depending on the required performance, ensures high torque even when working at very low speeds. In addition to all of this, it features an automatic energy-saving function which achieves significant consumption reductions, mainly in ventilation, water treatment and irrigation applications.
The CV30 can be incorporated into the vast majority of machinery, and can control pumps and fans. Some of its common applications are: belt conveyors, agitators, compressors, hoists, saws, vibrators, presses, polishers, barriers and high-speed doors, centrifugal and submersible pumps, blowers, separators, industrial washing machines, mobile trolleys, positioners, ornamental fountains, dispensers, air extraction equipment, fans, advertising and mobile stages, meat, textile and packaging machinery, etc.
Regardless of the model, all drives in the range feature a keypad as standard (removable or film type, depending on the model) and analogue or digital potentiometer.
Those up to 30 kW included feature a built-in dynamic braking unit, being only necessary to add an external braking resistor if this type of braking is required (high inertia loads or high braking frequency).
This enables the drives to be connected to a PC, configured and monitored to facilitate commissioning and maintenance.
Features:
- Import and export of drive parameter setting files.
- Display and modification of parameters.
- Quick comparison between programmed and default parameters.
- Oscilloscope with up to 10 channels, with data storage, export, etc.
- Multiple monitoring: one PC can monitor different drives at the same time.
They feature multi-step speed control, which enables the frequency setpoint to be selected by combining four multifunction inputs, obtaining up to 16 possible speeds.
In addition, using the simple PLC function, the CV30 and CV50 series enable the same 16 steps and their duration to be set, but without the need to use combinations of inputs. It is also possible to choose between performing the cycle repeatedly or carrying it out once.
This function, in many cases, removes the need to install an external control element.
The CV30 and CV50 series are equipped with a meter to measure the kWh consumed by the drive. This metering can be stopped in the event of testing, setting an initial value, resetting and accessing it via Modbus communication.
All drives include a Modbus RS-485 communication port, which allows communication with other devices such as PCs, PLCs, HMI, SCADA systems, etc.
The Modbus system is the most widespread in the industry, and has the greatest availability for the connection of industrial electronic devices.
