Adjustable Frequency Drive
I
DRIVE,MAX
The maximum output current.
I
DRIVE,N
The rated output current supplied by the adjustable
frequency drive.
U
DRIVE, MAX
The maximum output voltage.
Input
The connected motor can
start and stop with LCP and
the digital inputs.
Functions are divided into
two groups.
Functions in group 1 have
higher priority than
functions in group 2.

DRIVE
The efficiency of the adjustable frequency drive 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 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
(drive 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.
RefMAX
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
3-03 Maximum Reference
RefMIN
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 set in
3-02 Minimum Reference
