The maximum output voltage.
Output:
l
M
The current transmitted to the motor.
U
M
The voltage transmitted to the motor.
f
M
The frequency transmitted to the motor.
f
JOG
The frequency transmitted to the motor when the jog
function is activated (via digital terminals or the keypad).
f

η
VLT
The efficiency of the frequency converter is defined as
the ratio between the power output and the power input
.
Input:
C
ontrol command:
By means of LCP and the digital inputs, it is possible
to start and stop the connected motor.
Functions are divided into two groups, with
the following priorities:
Group 1 Reset, Coasting stop, Reset and

means of a single start signal in group 2.
A stop command given as a group 1 command
results in the display indication STOP.
A missing stop command given as a group 2 command
results in the display indication STAND BY.
S
tart-disable command:
A stop command that belongs to group 1 of the
control commands - see this group.
S
top command:
See Control commands.

The rated torque (motor).
References:
p
reset ref.
A firmly defined reference which can be set
from -100% to +100% of the reference range.
There are four preset references, which can be
selected via the digital terminals.
a
nalogue ref.
