1.7 Denitions
Frequency converter
I
VLT,MAX
The maximum output current.
I
VLT,N
The rated output current supplied by the frequency
converter.
U
VLT, MAX
The maximum output voltage.
Input
The connected compressor
can start and stop with the
LCP and the digital inputs.
Functions are divided into 2
groups.
Functions in group 1 have
higher priority than
functions in group 2.
Group
1
Reset, coast stop, Reset
and coast stop, quick
stop, DC brake, Stop, and
the [O] key.
Group
2
Start, pulse start,
Reversing, Start reversing,
Jog, and freeze output

(via digital terminals).
f
M
The motor frequency.
f
MAX
The maximum motor frequency.
f
MIN
The minimum motor frequency.
f

Torque
Illustration 1.1 Break-away Torque
η
VLT
The eciency of the frequency converter is dened 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 Table 1.3.
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
dened 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 is set in
parameter 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 is set in
parameter 3-02 Minimum Reference.
