The multi-function output settings (H2-oo = 18 and 19). 0: Disabled 1: oL4 at Speed Agree - Alarm (overtorque Detection only active during Speed Agree and Operation continues after detection). 2: oL4 at RUN - Alarm (overtorque Detection is always active and operation continues after detection). 3: oL4 at Speed Agree - Fault (overtorque Detection only active during Speed Agree and drive output will shut down on an oL4 fault). 4: oL4 at RUN - Fault (overtorque Detection is always active and drive output will shut down on an oL4 fault). 5: UL4 at Speed Agree - Alarm (undertorque Detection is only active during Speed Agree and operation continues after detection). 6: UL4 at RUN - Alarm (undertorque Detection is always active and operation continues after detection). 7: UL4 at Speed Agree - Fault (undertorque Detection only active during Speed Agree and drive output will shut down on an oL4 fault). 8: UL4 at RUN - Fault (undertorque Detection is always active and drive output will shut down on an oL4 fault)
- L6-05Error codeSets the overtorque/undertorque detection level. 100% is equal to the motor rated current in V/f Control or PM OLV and equal to the motor rated torque in Open Loop Vector Control
- L6-08Error codeThis function can detect an over/undertorque in a certain speed range as a result of machine fatigue. It is triggered by a certain operation time and uses the oL1 detection settings (L6-01 to L6-02) 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).

- L6-10Error codeSets the time a mechanical weakening has to be detected before an Alarm/Fault is triggered
- L7-01Error code• Sets the maximum torque for Open Loop Vector Control. • Ensure that the drive capacity is greater than the motor capacity when increasing this setting. Be careful when reducing this value because motor speed loss may occur with heavy loads
- L7-07Error codeSelects the method of torque limit control during accel/decel. 0: Proportional Control (change to integral controls at fixed speeds). Use this setting when acceleration to the desired speed has priority over torque limitation. 1: Integral Control. Use this setting if the torque limitation has priority. When torque limit is applied to the motor, accel/decel time may increase and motor speed may not meet the speed reference
- L8-01Error code0: Disabled. The drive will not provide overheat protection. Supply separate means of overheat protection. 1: Enabled. Braking Resistor is protected from overheat
- L8-02Error codeWhen the heatsink temperature exceeds the value set in this parameter, an Overheat Alarm (oH) will occur
- L8-03Error codeSets the drive operation when an overheat alarm oH is detected. 0: Ramp to Stop using the active decel time. 1: Coast to Stop. 2: Fast-stop using the time set in C1-09. 3: Alarm Only. Drive continues running, but displays an alarm. 4: Reduced Speed Operation. Drive continues to run with reduced frequency reference as specified in L8-19. Settings 0 through 2 trigger a fault relay if the heatsink becomes too hot
- L8-05Error codeSelects the detection of input current phase loss, power supply voltage imbalance, or main circuit electrolytic capacitor deterioration. 0: Disabled 1: Enabled Note: This parameter is disabled in 200 V single-phase drives
- L8-07Error codeSelects the output phase loss detection. 0: Disabled 1: Enabled (triggered by a single phase loss) 2: Enabled (triggered when two phases are lost) Output phase loss is detected when operating with less than 5% of the drive rated current. Detection can mistakenly occur if the motor is small relative to the drive capacity rating (this parameter should be disabled in such cases)
- L8-09Error codeSelects the output ground fault detection. 0: Disabled 1: Enabled
- L8-10Error codeControls the heatsink cooling fan operation. 0: Run with timer (Fan operates only during run and for L8-11 seconds after stop.) 1: Run always (Cooling fan operates whenever the drive is powered up.)
- L8-11Error codeThis parameter sets the delay time for the cooling fan to shut off after the run command is removed when L8-10 = 0
- L8-12Error codeUsed to input the ambient temperature. This value adjusts the drives oL2 detection level
- L8-18Error codeSelects the software current limit function. Typically no adjustment is required. 0: Disabled 1: Enabled

- L8-29Error codeSelects the detection of unbalanced output currents caused by faulty devices in the output circuit. 0: Disabled 1: Enabled
- L8-41Error code1: Enabled (alarm is output)
- L8-51Error codeSets the STo detection level as a percentage of the motor rated current. Increase this value to detect pull-out more quickly during acceleration. The drive calculates this value automatically when L8-51 is set to 0.0%
- low10Error codeDep. on drive capacity
- n1-01Error codeIf the motor vibrates while lightly loaded, Hunting Prevention may reduce the vibration. 0: Disabled 1: Enabled When quick response is needed disable Hunting Prevention
- n1-02Error codeSets the gain for the Hunting Prevention Function. If the motor vibrates while lightly loaded and n1-01 = 1, increase the gain by 0.1 until vibration ceases. If the motor stalls while n1-01 = 1, decrease the gain by 0.1 until the stalling ceases
- n3-01Error codeSets the output frequency reduction step width when the drive stops the motor using high-slip braking (HSB).
- n3-02Error codeSets the current limit during HSB. Higher n3-02 settings will shorten motor stopping times but increase the motor current, and therefore motor heating
- n3-03Error codeSets the time the drive will run with minimum frequency (E1-09) at the end of deceleration. If this time is set too low, the machine inertia can cause the motor to rotate slightly after HSB completion
- n3-04Error codeSets the time required for an HSB overload fault (oL7) to occur when the drive output frequency does not change during an HSB stop. This parameter does not typically require adjustment
- n3-21Error codeIf overcurrent or overload occur during high-slip deceleration, reduce the high-slip suppression current level. Set as a percentage of the drive rated current

- n8-47Error codeSets the time constant to make the pull-in current and actual current value agree. Decrease the value if the motor begins to oscillate. Increase the value if it takes too long for the current reference to equal the output current
- n8-48Error codeDefines the amount of current provided to the motor during no-load operation at a constant speed. Set as a percentage of the motor rated current. Increase this setting when hunting occurs while running at a constant speed
