YASKAWA ELECTRIC SIEP C710636 02B YASKAWA U1000 Technical Manual
All Modes
Sets the number of times the drive may attempt to restart after the following faults occur: GF,
LF, oC, oH1, oL1, oL3, oL4, ov, Sto, Uv1.
All Modes
0: Fault output not active.
1: Fault output active during restart attempt.
All Modes
Sets the amount of time to wait between performing fault restarts.
All Modes
0: Continuously attempt to restart while incrementing restart counter only at a successful
restarts (same as F7 and G7).
1: Attempt to restart with the interval time set in L5-04 and increment the restart counter with
each attempt (same V7).
All Modes
0: Disabled
1: oL3 detection only active during speed agree, operation continues after detection
2: oL3 detection always active during run, operation continues after detection
3: oL3 detection only active during speed agree, output shuts down on an oL3 fault
4: oL3 detection always active during run, output shuts down on an oL3 fault
5: UL3 detection only active during speed agree, operation continues after detection
6: UL3 detection always active during run, operation continues after detection
7: UL3 detection only active during speed agree, output shuts down on an oL3 fault
8: UL3 detection always active during run, output shuts down on an oL3 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 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.
All Modes
Sets the operation time (U1-04) required before Mechanical Weakening Detection is active.
