L6-02: Torque Detection Level 1
L6-03: Torque Detection Time 1
L6-05: Torque Detection Level 2
L6-06: Torque Detection Time 2
Figure 5.85 Time Chart for Undertorque Detection
Note:
The drive applies a hysteresis of approximately 10% of the drive rated output current or the motor rated torque to the overtorque/
undertorque/underload detection function.
Underload Detection Time Chart
When
L6-01 = 9 [UL6 @ Speed Agree - Alarm only] to 12 [UL6 @ RUN - Fault]
, the drive will detect underload if
the motor current or output torque is less than or equal to the detection level for the time set in
L6-03
.
Note:
The linear curve of
L6-02
,
L6-13 [Motor Underload Curve Select]
, and
L6-14 [Motor Underload Level @ Min Freq]
sets the underload
detection level.
Use
H2-01 to H2-03 [MFDO Function Selection]
to set the terminal that outputs the alarm.
H2-xx = 58: UL6 Underload Detected
L6-03: Torque Detection Time 1
L6-14: Motor Underload Level @ Min Freq

Note:
The drive applies a hysteresis of approximately 10% of the drive rated output current or the motor rated torque to the overtorque/
undertorque/underload detection function.

Torque Detection Selection 1 Sets the speed range that detects overtorque and undertorque and the operation of drives (operation
status) after detection.

(0 - 12)
•
The drive detects
oL [overtorque]
if the motor current or output torque is more than the level set in
L6-02 [Torque
Detection Level 1]
for the time set in
L6-03 [Torque Detection Time 1]
.
•
The drive detects
UL [undertorque]
if the motor current or output torque is less than the level set in
L6-02
for the
time set in
L6-03
.
•
The drive detects
UL6 [Underload or Belt Break Detected]
if the motor current or output torque is less than the
linear curve set in
L6-02
and
L6-14 [Motor Underload Level @ Min Freq]
.
0 : Disabled
The drive will not detect overtorque or undertorque.
1 : oL @ Speed Agree - Alarm only
