Determines the drive's response to an overtorque/undertorque condition.
Overtorque and Undertorque are determined by the settings in parameters
L6-02 and L6-03.
0: Disabled
1: OL@SpdAgree - Alm (Overtorque Detection only active during Speed
Agree and Operation continues after detection)
2: OL At RUN - Alm (Overtorque Detection is always active and operation
continues after detection)
3: OL@SpdAgree - Flt (Overtorque Detection only active during Speed
Agree and drive output will shut down on an OL3 fault.)
4: OL At RUN - Flt (Overtorque Detection is always active and drive
output will shut down on an OL3 fault.)
5: LL@SpdAgree - Alm (Undertorque Detection is only active during
Speed Agree and operation continues after detection.)
6: LL at RUN - Alm (Undertorque Detection is always active and
operation continues after detection.)
7: LL @ SpdAgree - Flt (Undertorque Detection only active during Speed
Agree and drive output will shut down on an OL3 fault.)
8: LL At RUN - Flt (Undertorque Detection is always active and drive
output will shut down on an OL3 fault.)
Sets the overtorque/undertorque detection level as a percentage of drive
rated current.
Sets the length of time an overtorque/undertorque condition must exist
before being recognized by the drive. OL3 is then displayed.
0: Not Provided
1: Provided
When the cooling fin temperature exceeds the value set in this parameter,
an overheat pre-alarm (OH) will occur.
Drive Operation upon OH Pre Alarm Detection.
0: Ramp to Stop (Decel Time C1-02).
1: Coast to Stop
2: Fast-Stop (Decel Time = C1-09).
3: Alarm Only
*0 to 2 is recognized as fault detection, and 3 is recognized as alarm. (For
the fault detection, the fault contact operates.)
4: OH Alarm & Reduce (Continue operation and reduce output frequency
by L8-19)
Selects the detection of input current phase loss, power supply voltage
imbalance, or main circuit electrostatic capacitor deterioration.
0: Disabled
1: Enabled
Monitors the DC Bus current ripple and activates when one of the input
phases is lost (PF).
Selects the detection of output current open-phase.
When applied motor capacity is too small for drive capacity, output phase
loss may be detected inadvertently. In this case, set to 0.
0: Disabled
1: Enabled
Enables and disables drive output ground fault detection.
0: Disabled
1: Enabled
Controls the Heatsink Cooling Fan Operation.
0: Fan On-Run Mode (Fan will operate only when drive is running and for
L8-11 seconds after RUN is removed).
1: Fan Always On (Cooling fan operates whenever drive is powered up.)
When L8-10=0 this parameter sets a delay time for Cooling Fan de-
energization after the run command is removed or baseblock enabled.
When the drive is installed in an ambient temperature exceeding its rating,
drive overload (OL2) protection level is reduced.
