Danfoss FC 102 Design Guide

1.1.1 Definitions
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:
Control command
Start and stop the
connected motor with the
LCP or the digital inputs.
Functions are divided into
two groups.
Functions in group 1 have
higher priority than
functions in group 2.
Group
1
Reset, Coasting stop, Reset
and Coasting stop, Quick-
stop, DC braking, Stop and
the "Off" key.
Group
2
Start, Pulse start, Reversing,
Start reversing, Jog and
Freeze output
Table 1.4 Function Groups
Motor:
f
JOG
The motor frequency when the jog function is activated
(via digital terminals).
f
M
The motor frequency.
f
MAX
The maximum motor frequency.
f
MIN
The minimum motor frequency.
f
M,N
The rated motor frequency (nameplate data).
I
M
The motor current.
I
M,N
The rated motor current (nameplate data).
n
M,N
The rated motor speed (nameplate data).
P
M,N
The rated motor power (nameplate data).
T
M,N
The rated torque (motor).
U
M
The instantaneous motor voltage.
U
M,N
The rated motor voltage (nameplate data).

Illustration 1.1 Break-away Torque
η
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 Table 1.4.
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.
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
3-03 Maximum Reference.
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
3-02 Minimum Reference
