Definitions
AKD:
I
AKD,MAX
The maximum output current.
I
AKD,N
The rated output current supplied by the
frequency converter.
U
AKD MAX
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
MIN
The minimum frequency transmitted to the motor.
f
MAX
The maximum frequency transmitted to the motor.
Break-away torque:
η
AKD
The efficiency of the frequency converter is defined as
the ratio between the power output and the power input.
Input:
Control 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:
MG.50.R3.02 -
AKD 5000
Group 1 Reset, Coasting stop, Reset and
Coasting stop, Quick-stop, DC
braking, Stop and the "Stop" key.
Group 2 Start, Pulse start, Reversing,
Start reversing, Jog and Freeze
output
Group 1 functions are called Start-disable commands.
The difference between group 1 and group 2 is that
in group 1 all stop signals must be cancelled for the
motor to start. The motor can then be started by
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.
Start-disable command:
A stop command that belongs to group 1 of the
control commands - see this group.
Stop command:
See Control commands.
Motor:
I
M,N
The rated motor current (nameplate data).
f
M,N
The rated motor frequency (nameplate data).
U
M,N
The rated motor voltage (nameplate data).
P
M,N
The rated power delivered by the motor
(nameplate data).
n
M,N
The rated motor speed (nameplate data).
T
M,N
The rated torque (motor).
References:
preset 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.
analogue ref.
A signal transmitted to input 53, 54 or 60.
Can be voltage or current.
