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 input s 53 or 54, can be voltage or current.
Binary Reference
A signal transmitted to the serial communication port.
Preset Reference
A defined preset reference to be set from -100% to +100% of the reference range. Selection of eight
preset references via the digital terminals.
Pulse Reference
A pulse frequency signal transmitted to the digital inputs (terminal 29 or 33).
Ref
MAX
Determines the relationship between the reference input at 100% full scale value (typically 10 V, 20mA)
and the resulting reference. The maximum reference value set in par. 3-03.
Ref
MIN
Determines the relationship between the reference input at 0% value (typically 0V, 0mA, 4mA) and the
resulting reference. The minimum reference value set in par. 3-02.
Miscellaneous:
Analog Inputs
The analog inputs are used for controlling various functions of the frequency converter.
There are two types of analog inputs:
Current input, 0-20 mA and 4-20 mA
Voltage input, 0-10 V DC (FC 301)
Voltage input, -10 - +10 V DC (FC 302).
Analog Outputs
The analog outputs can supply a signal of 0-20 mA, 4-20 mA, or a digital signal.
