All Modes
For V/f control, set the level as a percentage of the drive rated output
current.
For Vector control, set the level as a percentage of the motor rated torque.
All Modes
Sets the time an overtorque or undertorque condition must exist to trigger
torque detection 1.
All Modes
0: Disabled
1: oL4 detection only active during speed agree, operation continues after
detection
2: oL4 detection always active during run, operation continues after
detection
3: oL4 detection only active during speed agree, output shuts down on an
oL4 fault
4: oL4 detection always active during run, output shuts down on an oL4
fault
5: UL4 detection only active during speed agree, operation continues after
detection
6: UL4 detection always active during run, operation continues after
detection
7: UL4 detection only active during speed agree, output shuts down on an
oL4 fault
8: UL4 detection always active during run, output shuts down on an oL4
fault
All Modes
Sets the overtorque and undertorque detection level.
All Modes
Sets the time an overtorque or undertorque condition must exist to trigger
torque detection 2.
All Modes
This function can detect an overtorque or undertorque in a certain speed
range as a result of machine fatigue. It is triggered by a specified operation
time and uses the oL1 detection settings (L6-01 and L6-03)
0: Mechanical Weakening Detection disabled.
1: Continue running (alarm only). Detected when the speed (signed) is
greater than L6-09.
2: Continue running (alarm only). Detected when the speed (not signed) is
greater than L6-09.
3: Interrupt drive output (fault). Detected when the speed (signed) is
greater than L6-09.
4: Interrupt drive output (fault). Detected when the speed (not signed) is
greater than L6-09.
5: Continue running (alarm only). Detected when the speed (signed) is less
than L6-09.
6: Continue running (alarm only). Detected when the speed (not signed) is
less than L6-09.
7: Interrupt drive output (fault). Detected when the speed (signed) is less
than L6-09.
8: Interrupt drive output (fault). Detected when the speed (not signed) is
less than L6-09.
All Modes
Sets the speed that triggers Mechanical Weakening Detection. When L6-
08 is set for an unsigned value, the absolute value is used if the setting is
negative.
All Modes
Sets the time mechanical weakening has to be detected before an alarm or
fault is triggered.
