Yaskawa Z1000U HVAC Matrix Bypass - Manual (Page 191)

No. Name Setting Range Default
L6-01 Torque Detection Selection 1 0 to 8 0
Setting 0: Disabled
Setting 1: oL3 at Speed Agree (Alarm)
Overtorque detection is active only when the output speed is equal to the frequency reference (i.e., no detection during
acceleration and deceleration). The operation continues after detecting overtorque and triggering an oL3 alarm.
Setting 2: oL3 at Run (Alarm)
Overtorque detection works as long as the Run command is active. The operation continues after detecting overtorque and
triggering an oL3 alarm.
Setting 3: oL3 at Speed Agree (Fault)
Overtorque detection is active only when the output speed is equal to the frequency reference (i.e., no detection during
acceleration and deceleration). The operation stops and triggers an oL3 fault.
Setting 4: oL3 at Run (Fault)
Overtorque detection works as long as a Run command is active. The operation stops and triggers an oL3 fault.
Setting 5: UL3 at Speed Agree (Alarm)
Undertorque detection is active only when the output speed is equal to the frequency reference (i.e., no detection during
acceleration and deceleration). The operation continues after detecting overtorque and triggering a UL3 alarm.
Setting 6: UL3 at Run (Alarm)
Undertorque detection works as long as the Run command is active. The operation continues after detecting overtorque and
triggering a UL3 alarm.
Setting 7: UL3 at Speed Agree (Fault)
Undertorque detection is active only when the output speed is equal to the frequency reference (i.e., no detection during
acceleration and deceleration). The operation stops and triggers a UL3 fault.
Setting 8: UL3 at Run (Fault)
Undertorque detection works as long as a Run command is active. The operation stops and triggers a UL3 fault.
n L6-02: Torque Detection Level 1
Sets the detection levels for torque detection function 1 as a percentage of the drive rated output current.
No. Name Setting Range Default
L6-02 Torque Detection Level 1 0 to 300% 15%
Note: The torque detection level 1 (L6-02) can also be supplied by an analog input terminal set to H3-oo = 7. Here, the analog value has priority
and the setting in L6-02 is disregarded.
n L6-03: Torque Detection Time 1
Determines the time required to trigger an alarm or fault after exceeding the level in L6-02.
No. Name Setting Range Default
L6-03 Torque Detection Time 1 0.0 to 10.0 s 10.0 s
n L6-13: Motor Underload Protection Selection
Sets Motor Underload Protection (UL6) based on motor load and determines whether the level of L6-02 refers to fbase or
fmax.
Selects the operation of underload detection UL6. Underload is detected when the output current falls below the underload
detection level defined by L6-14 and L2-02.
No. Name Setting Range Default
L6-13 Motor Underload Protection Selection 0, 1 0
