VLT
The efficiency of the frequency converter is defined as the
ratio between the power output and the power input.
Start-disable command
A stop command belonging to the group 1 control
commands - see this group.
Stop command
See Control commands.
References
Analog reference
A signal transmitted to the analog inputs 53 or 54, can be
voltage or current.
Bus reference
A signal transmitted to the serial communication port (FC
port).
Preset reference
A defined preset reference to be set from -100% to +100%
of the reference range. Selection of 8 preset references via
the digital terminals.
Ref
MAX
Determines the relationship between the reference input
at 100% full scale value (typically 10 V, 20 mA) and the
resulting reference. The maximum reference value set in
3-03 Maximum Reference .
Ref
MIN
Determines the relationship between the reference input
at 0% value (typically 0 V, 0 mA, 4 mA) and the resulting
reference. The minimum reference value set in
3-02 Minimum Reference
Miscellaneous
Analog inputs
The analog inputs are used for controlling various
functions of the frequency converter.
There are 2 types of analog inputs:
Current input, 0-20 mA and 4-20 mA
Voltage input, 0-10 V DC.
Analog outputs
The analog outputs can supply a signal of 0-20 mA, 4-20
mA, or a digital signal.
Automatic Motor Adaptation, AMA
AMA algorithm determines the electrical parameters for
the connected motor at standstill.
Digital inputs
The digital inputs can be used for controlling various
functions of the frequency converter.
Digital outputs
The frequency converter features 2 Solid State outputs that
can supply a 24 V DC (max. 40 mA) signal.
Relay outputs
The frequency converter features two programmable Relay
Outputs.
ETR
Electronic Thermal Relay is a thermal load calculation
based on present load and time. Its purpose is to estimate
the motor temperature.
Initialising
If initialising is carried out ( 14-22 Operation Mode ), the
programmable parameters of the frequency converter
return to their default settings.
Initialising;
14-22 Operation Mode will not initialise
communication parameters.
