VLT® 5000 Crane
Programming
generated current becomes higher than the torque
limit (set in parameter 222).
Quick-stop is activated by means of a signal on digital
input terminal 27, or via the serial communication port.
213 JOG FREQUENCY
Value:
0 - 4500 RPM
✭
200 RPM
Function:
Jog frequency f
JOG
means a fixed output frequency
that the frequency converter supplies to the motor
when the Jog function is activated. Jog can be
activated via the digital inputs, serial communication
or via the LCP control panel, on the condition that
this is active in parameter 015 Local jogging .
NB!:
Note that this function only is availabel
when running in FC profile!
Description of choice:
Set the required frequency.
221 TORQ LIMIT MOTOR
Value:
0.0 % - 170% ✭
160 %
Function:
This is where to set the torque limit for motor operation.
The torque limiter is active in the frequency range
up to the rated motor frequency (parameter 104).
In the oversynchronous range, this function acts
as a current limiter, see figures below.
Description of choice:
In order to protect the motor from reaching pull-out
torque, the factory setting is 1.6 x the rated
motor torque (calculated value).
If a setting in parameters 101-106 is changed,
parameters 221/222 are not automatically
reversed to the factory setting.
222 TORQ LIMIT GENER
Value:
0.0 % - 170%
✭
160 %
Function:
This is where to set the torque limit for generating
operation. 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 figures for parameter 221.
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.
234 MISSING MOTOR PHASE
Value:
* Enable (ENABLE) [0]
Disable (DISABLE) [1]
Function:
In this parameter it is possible to select monitoring
of the motor phases.
Description of choice:
If Enable is selected, the frequency converter
will react on a missing motor phase which will
result in alarm 30, 31 or 32.
