Danfoss VLT 5000 Series User Manual

Function:
This function is relevant for all application configura-
tions; speed, process and torque control.
This is where to set the torque limit for generating op-
eration. The torque limiter is active in the frequency
range up to the rated motor frequency (parameter
104).
In the oversynchronous range, where the frequency is
higher than the rated motor frequency, this function
acts as a current limiter.
See fig. for parameter 221 as well as parameter 409
for further details.
Description of choice:
If Resistor brake [1] has been selected in parameter
400, the torque limit is changed to 1.6 x the rated motor
torque.
223 Warning: Low current
(WARN. CURRENT LO)
Value:
0.0 - parameter 224
0.2 A
Function:
When the motor current is below the limit, I
LOW
pro-
grammed in this parameter, the display indicates
CURRENT LOW.
The signal outputs can be programmed to transmit a
status signal via terminal 42 or 45 as well as via relay
output 01 or 04 (parameter 319, 321, 323 or 326).
Description of choice:
The lower signal limit I
LOW
of the motor current must
be programmed within the normal working range of the
adjustable frequency drive.
224 Warning: High current
(WARN. CURRENT HI)
Value:
Parameter 223 - I
VLT,MAX
I
VLT,MAX
Function:
f the motor current gets above the limit programmed in
this parameter, I
HIGH
, the display will indicate CUR-
RENT HIGH.
The signal outputs can be programmed to transmit a
status signal via terminal 42 or 45 and via relay output
01 or 04 (parameter 319, 321, 323 or 326).
Description of choice:
The upper signal limit of the motor current, I
HIGH
, must
be programmed within the normal working range of the
adjustable frequency drive.
225 Warning: Low frequency
(WARN. FREQ. LOW)
Value:
0.0 - parameter 226
0.0 Hz
Function:
When the motor frequency is below the limit program-
med in this parameter, f
LOW
, the display indicates FRE-
QUENCY LOW.
