Programming
Description of choice:
See also parameter 409 for further details.
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.
Changing parameter 221 (TORQ LIMIT
MOTOR) when parameter 100 is set
to SPEED OPEN LOOP (0), parameter
236 (LOW SPEED CURRENT) will automatically be
readjusted. If parameter 221 > parameter 236, a
potential risk for motor stalling occurs.
222 Torque limit for generating operation
(TORQ LIMIT GENER)
Value:
0.0 % - xxx.x % of T
M,N
✭
160 % of T
M,N
The max. torque depends on the unit, the selected
motor size and parameters.
Function:
This parameter sets the torque limit for generating
operation. The torque limiter is active in the speed
range up to the rated motorspeed (parameter 104).
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.
Changing parameter 222 (TORQ LIMIT
GENER) when parameter 100 is set
to SPEED OPEN LOOP (0), parameter
236 (LOW SPEED CURRENT) will automatically be
readjusted. If parameter 222 > parameter 236, a
potential risk for motor stalling occurs.
223 Warning: Low current
(WARN. CURRENT LO)
Value:
0.0 - parameter 224
✭
0.0 A
Function:
When the motor current is below the limit, I
LOW
,
the display indicates CURRENT LOW, except if
mechanical brake control is selected.
The signal outputs can be programmed to produce a
status signal on terminal 26 or 46 as well as on 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 frequency converter.
224 Warning: High current
(WARN. CURRENT HI)
Value:
Parameter 223 - I
VLT,MAX
✭
I
VLT,MAX
Function:
If the motor current exceeds the programmed limit,
I
HIGH
, the display will indicate CURRENT HIGH.
The signal outputs can be programmed to produce a
status signal on terminal 26 or 46 and on relay output
01 or 04 (parameter 319, 321, 323 or 326).
