Denitions
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.
Group 1
Reset, coast stop, reset and coast stop, quick
stop, DC brake, stop, and
[O].
Group 2
Start, pulse start, reversing, start reversing, jog,
and freeze output.

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 nominal motor speed (nameplate data).
P
M,N
The rated motor power (nameplate data).
U
M
The instantaneous motor voltage.
U
M,N
The rated motor voltage (nameplate data).
Break-away torque
Illustration 1.1 Break-away Torque
η
DRIVE
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 Table 1.3.
Analog reference
A signal transmitted to the analog inputs 53 or 54. It can
be voltage or current.
•
Current input: 0–20 mA and 4–20 mA
•
Voltage input: 0–10 V DC
Bus reference
A signal transmitted to the serial communication port
(drive 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 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.
