Configuration Parameter
Overtorque/Undertorque Detection 1
Overtorque/Undertorque Detection 2
Detection Time
L6-03
L6-06
*1
You can also use an analog input terminal to supply the torque detection level. To enable this function, set
H3-xx = 7 [MFAI Function
Selection = Overtorque/Undertorque DetectLvl]
. If both
L6-02
and
H3-xx = 7
are set, the analog input has priority and the setting of
L6-
02
is disabled.
You cannot use Overtorque/Undertorque Detection 2 to set the detection level for the analog input terminals.
Note:
In V/f Control, the drive uses the current level (100% of the drive rated output current) to detect overtorque/undertorque. In vector control,
the drive uses the motor torque (100% of the motor rated torque)to detect overtorque/undertorque. When you enable the mechanical
weakening detection function, the overtorque/undertorque detection level for all control modes is the current level (100% of the drive rated
output current).

Time Chart for Detection of Overtorque/Undertorque
Overtorque Detection Time Chart
When you use Overtorque/Undertorque Detection 1, the drive detects overtorque if the motor current or motor torque
is at the detection level set in
L6-02 [Torque Detection Level 1]
for the time set in
L6-03 [Torque Detection Time 1]
.
Parameter
L6-01 [Torque Detection Selection 1]
sets the operation after detection.
When you use Overtorque/Undertorque Detection 2, set
L6-04 [Torque Detection Selection 2]
,
L6-05 [Torque
Detection Level 2]
, and
L6-06 [Torque Detection Time 2]
.
Use
H2-01 to H2-03 [MFDO Function Select]
to set the terminal that outputs the alarm.
Figure 12.139 Overtorque Detection Time Chart
Note:
The drive applies a hysteresis of approximately 10% of the drive rated output current or the motor rated torque to the overtorque/undertorque
detection function.
Undertorque Detection Time Chart
When you use Overtorque/Undertorque Detection 1, the drive detects undertorque if the motor current or motor
torque is less than or equal to the detection level set in
L6-02
for the time set in
L6-03
. Parameter
L6-01
sets the
operation after detection.
When you use Overtorque/Undertorque Detection 2, set the operation in
L6-04, L6-05, and L6-06
.
Use
H2-01 to H2-03 [MFDO Function Select]
to set the terminal that outputs the alarm.
Figure 12.140 Undertorque Detection Time Chart
Note:
The drive applies a hysteresis of approximately 10% of the drive rated output current or the motor rated torque to the overtorque/undertorque
detection function.
