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.
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

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
