Vacon NX applications

Vacon NXL applications

ALFIFF06 NXL Multi-Purpose Application

Based on the Vacon NXL Multi-Control application without PID and PFC control. The application supports the use of I/O boards in both option board slots (D, E).

This application has automatic motor identification for tuning of the U/f curve and Rs Voltage drop (like in the Vacon NXS). More features are added to this application such as parameters for mechanical brake control, fieldbus process data out selection and 8 preset speeds.

ALFIFF26 NXL Multi-Motor Application

This is NXL Multi-Control Application without PID and PFC control. 2 Motor parameter sets are included. Different sets are selected by digital input. Typically used by OEM customers when 2 different types of motors are used with same frequency converter.

Note: Motors cannot be used at the same time.

ALFIFF27 NXL Local/Remote Application

Local/Remote application is designed for the cases, where the frequency converter must be controlled from two different control places. Usually local control place is panel and remote control place is I/O-terminal or fieldbus. For each control place the frequency reference can be selected from the panel, I/O (current or voltage input), fieldbus or motor potentiometer. Active control place is selected with digital input DIN6.

Local/Remote application has the same parameter groups than in Standard application.

ALFIFF28 NXL Lift Application

NXL Application is designed be used in elevators. It has same functionality as in NXS (open loop) lift application.

Speed reference creation methods specially designed for easy integration to lift control logics. There are separate parameter groups for controlling the mechanical brake. Application can be used also in cranes but the ALFIFF30 application is preferred.

ALFIFF30 Brake control Application

The Brake Control Application is typically used in applications where mechanical brake control is needed. Mainly used in hoists and cranes.

The frequency reference can be selected from the analogue inputs, fieldbus, keypad, preset speeds, motor potentiometer or 8 binary coded speed references. Separate parameter groups for controlling the mechanical brake with different settings in forward and reverse direction. The option board NXOPTAA is recommended to be used.

ALFIFF32 NXL PID Fire mode application

The NXL Fire mode application has the same functionality as the Multi-Control application (ALFIFF20) but the PFC functions are removed and are replaced by the fire mode features.

Fire mode application is used in ventilation systems of buildings. During a fire in the building fire mode can be activated and then all faults will be automatically reset from the drive. This will allow drive run until it is totally damaged or fire mode is deactivated. Idea is to keep hallways overpressure during the fire and smoke out of the hallways.

Fire mode is activated via a digital input (programmable).

Note: Fire mode activation will void warranty.

When fire mode is active, a fire mode warning (A81) is brought up on the display. When running in fire mode, the converter is programmed to enable the user to run the converter until either the digital input is removed or the converter is damaged

Vacon NXS applications

ASFIFF08 Standard Lift Application

The Lift Application can be used with modern Lift systems. There are functions included that are required to achieve a smooth ride in the lift car. The I/O interface table includes the most commonly needed signals in lift applications.

In the application, constant speeds are presented in [m/s] and also in [Hz], acceleration and deceleration are presented in [m/s2] and jerks are presented in [ms]. Mechanical brake control logic is designed to achieve smooth departures from and landings to floor level. The brake can be set in various ways to meet the different requirements of lift motors and lift control logic.

The used hardware can be any Vacon NXS or NXP frequency converter. In closed loop motor control mode NXP drive and encoder option board is required (NXOPTA4 or NXOPTA5).

All outputs are freely programmable. Digital input functions are freely programmable to any digital input. Start forward and reverse signals are fixed to input DIN1 and DIN2 (see next page).

If Permanent magnet synchronous motor is needed to run then select application APFIFF33 NXP Lift application.

ASFIFF11 Fire mode PID application

Fire mode application is used in ventilation systems of buildings. During a fire in the building fire mode can be activated and then all faults will be automatically reset from the drive. This will allow drive run until it is totally damaged or fire mode is deactivated. Idea is to keep hallways overpressure during the fire and keep the smoke out of the hallways.

The Fire Mode PID application is functionally the same as the PID application of the “AII IN ONE” package. The Fire Mode function is activated with DIN.

When running in fire mode, the converter is programmed to enable the user to run the converter until either the digital input is removed or the converter is damaged

Note: Fire mode activation will void warranty.

ASFIG100 Water Solutions application package (WATER PACKAGE)

The package includes the following applications:

(See detailed description from individual applications)

  • Basic (ASFIFF01)
  • MultiMasterPFC (ASFIFF09)
  • Advanced Level Control (ASFIFF24)
  • MultiFollowerPFC(ASFIFF30)

ASFIF09 Multi-Master PFC (WATER PACKAGE)

The application is designed to achieve an even wear of the pumps connected to the motors/drives by regularly changing the regulating order of the drives. The application supports max. 3 devices to work in parallel. One drive is leading and regulating (PID) while the others are either stand-by or running at the speed producing the nominal flow in the system.

The autochange of the regulating drive/pump can be performed during run without any notice in the pressure in the pipes. This means also that each drive can become the regulating drive of the system.

Due to the fact that all 3 devices are controlled by its own drive, will the system be controlled even if one or two of the drives are tripped.

ASFIFF24 Advanced Level Control application (WATER PACKAGE)

With the Advanced Level Control application you can build a system where up to 3 drives control the pumping from a storage tank.

One frequency converter controls the pump that is the leading pump and handles the main regulation and the other ones are started if the liquid level in the tank is close to reaching the edge of the tank.

This system guarantees that the flow from the tank remains as steady as possible. In case of excessive amount of water in the tank for the leading pump to handle and the buffering capacity of the tank is not enough the auxiliary pumps will start before the tank flows over.

The application is designed to achieve an even wear of the pumps connected to the motors/drives by regularly changing the regulating order of the drives. The application supports max. 3 devices to work in parallel.

The autochange of the regulating drive/pump can be performed during run without any notice in the flow in the pipes. This means also that each drive can become the regulating drive of the system.

Due to the fact that all 3 devices are controlled by its own drive, will the system be controlled even if one or two of the drives are tripped.

ASFIFF30 MultiFollower PFC (WATER PACKAGE)

The application is designed to achieve an even wear of the pumps connected to the motors/ drives by regularly changing the regulating order to of the drives. The application supports the maximum of 3 pumps, fans or compressors to work in parallel.

One drive is leading and regulating (PID) while the others are either stand-by or, if working as auxiliary drives, following the same speed that the leading one is running at.

The autochange of the regulating drive/pump can be performed during run without any notice in the pressure in the pipes. This means also that each drive can become the regulating drive of the system.

Due to the fact that all 3 devices are controlled by its own drive, will the system be controlled even if one or two of the drives are tripped.

This application is a development of the MultiMaster PFC application. In this application will the auxiliary drives run at the same speed as the master, i.e. the regulating drive.
