Wizards
Basic Commissioning
The basic commissioning of the Inverter and motor comprises a number of processes. The
processes are as follows:
● Basic commissioning
● Application class and control mode
● Calculation of motor and control data
The wizard will guide the user through the basic commissioning process by presenting a
number of screens where the user can choose the necessary options and values to
commission the Inverter and motor. At the conclusion of the basic commissioning process,
the data can be saved to the Inverters memory.
Open Loop Compressor
The Inverter is used to control the output pressure of a compressor to ensure that it adapts
to the varying volume of gas that is required to be compressed.
Compressing the gas involves reducing the volume and increasing the pressure within the
container to compress the gas.
The setpoint is controlled by the analog inputs.
Fixed Closed Loop Compressor
A constant pressure is required to be maintained within a system utilizing the minimum use
of energy.
The pressure in the system is monitored using the PID controller and if the pressure remains
constant then the Inverter will run the system at the minimum frequency to maintain the
pressure.
The setpoints are controlled by analog input 0.
The feedback from the system are received from the pressure sensor utilizing analog input 1.
This feedback is then used by the Inverter to react to changes in the system pressure.
The on/off and reset commands are controlled using digital inputs 0 and 1 respectively.
The general monitoring of the condition of the Inverter is achieved using digital outputs 0, 1
and 2 for drive failure, drive ready and drive running respectively.
Open Loop Fan
This is a basic fan application where the fan is under the control of the Inverter.
Fixed Closed Loop Fan
The purpose of the closed-loop controlled fan application is to maintain a constant airflow
within a ventilation system, utilizing as little energy as possible.
A specific airflow and pressure for the fan system is set within the Inverter and these values
are directly monitored using the PID controller. Depending on a decrease or increase in
pressure readings, the Inverter will increase or decrease the speed of the fan accordingly.
