Frequency converter
I
DRIVE, MAX
The maximum output current.
I
DRIVE, N
The rated output current supplied by the frequency
converter.
U
DRIVE, MAX
The maximum output voltage.
Input
The connected motor can start and stop via LCP and
digital inputs. Functions are divided into 2 groups, as
described in Table 1.3. Functions in group 1 have higher
priority than functions in group 2.
Reset, coast stop, reset and coast stop, quick
Group 1
stop, DC brake, stop, and [Off].
Start, pulse start, reversing, start reversing, jog,
Group 2
and freeze output.

Break-away torque
Illustration 1.1 Break-away Torque
η
DRIVE
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 1.3.
Stop command
See Table 1.3.
Analog reference
A signal transmitted to the analog inputs 53 or 54. It can
be voltage or current.
•
•
Bus reference
A signal transmitted to the serial communication port
(drive 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
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.
