When actual torque is within F4.24 (torque
detection time) and continuously greater than
F4.23 (torque detection level), the VFD will
respond with corresponding action according
to F4.22 setting. The torque detection value
corresponds to the motor rated torque when
set specified as 100%.
0: detection invalid
No torque detection is processed.
1: continue running after over-torque detected
during constant speed running.
Only detect over-torque during constant
speed running, and keep on running after it
is detected.
2: continue running after over-torque detected
during running
Detect over-torque during the whole
running process, and keep on running after
it is detected.
3: output cut off after over-torque detected
during constant speed running
Over-torque is only detected during
constant speed running, and after over-
torque detected, the VFD will stop output
and the motor will coast to stop.
4: output cut off after over-torque detected
during running
Over-torque is detected during the whole
running process, and after over-torque
detected, the VFD will stop output and the
motor will coast to stop.
5: continue running after insufficient torque
detected during constant speed running
Only detect insufficient torque during
constant speed running, and the VFD
keeps on running after insufficient torque
detected.
6: continue running after insufficient torque
detected during running
Detect insufficient torque during the whole
running process, and the VFD keeps on
running after it is detected.
7: output cut off after insufficient torque
detected during constant speed running
Only detect insufficient torque during
constant speed running, and after it is
detected, the VFD will stop output and the
motor will coast to stop.
8: output cut off after insufficient torque
detected during running
Detect insufficient torque during the whole
running process, and after it is detected,
the VFD will stop output and the motor will
coast to stop.
F5 VF control parameter
F5.00
V/F curve setting
0 ～ 5
0
This group of parameters are used to define
motor V/F setting mode to cater for different
load characteristic. Five fixed curves and one
user-defined curve can be selected according
to the setting of F5.00.
0: linear curve
Linear curve is suitable for common
constant torque type load, output voltage
and output frequency are in linear relation,
as straight line 0 showed in Fig. F5-1.
1: decreasing torque curve 1 (power of 1.3)
Decreasing torque curve 1, output voltage
value is output frequency value to the
power of 1.3, as curve 1 showed in Fig. F5-1.
2: decreasing torque curve 2 (power of 1.5)
Decreasing torque curve 2, output voltage
value is output frequency value to the
power of 1.5, as curve 2 showed in Fig. F5-1.
3: decreasing torque curve 3 (power of 1.7)
Decreasing toque curve 3, output voltage
value is output frequency value to the
power of 1.7, as curve 3 showed in Fig.F5-1.
