Figure 12.126 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.
■
Mechanical Weakening Detection
The Mechanical Weakening Detection function detects the mechanical weakening of a machine that can cause
overtorque or undertorque because of motor speed and total drive operation time.
The drive activates the function if the drive total operation time is longer than the time set in
L6-11 [MechFatigue
Hold Off Time]
. You can use
U4-01 [Cumulative OpeTime]
to monitor the total operation time.
Parameter Settings
If overtorque or undertorque occur during the speed range set in
L6-08 [MechF Enable]
and
L6-09 [MechFatigue
Speed Detect Level]
for the length of time set in
L6-10 [MechFatigue Delay Time]
, the drive will detect
Mechanical Weakening. The drive uses
L6-01 to L6-03
to detect
oL5 [Mechanical Weakening Detection 1]
or
UL5
[Mechanical Weakening Detection 2]
. Parameter
L6-08
sets the operation after detection.
Set the terminal that outputs the fault in
H2-01 to H2-03 [MFDO Function Select]
.

Trq Det1 Select
Enables overtorque and undertorque detection and the operation of drives (operation status) after
detection.

(0, 1)
The drive detects overtorque if the motor current or output torque is more than the level set in
L6-02 [Trq Det1
Level]
for the length of time set in
L6-03 [Trq Det1 Time]
. The drive detects undertorque if the motor current or
output torque is less than the level set in
L6-02
for the length the time set in
L6-03
.
0 : Disabled
The drive will not detect overtorque or undertorque.
1 : Enabled
The behavior is adjusted using parameters
