Codes
- L2-11Error codeSets the desired value of the DC bus voltage during KEB
- L3-01Error code• Prevents motor speed loss and overvoltage. Used when the load is too heavy and also during sudden acceleration/deceleration. • Adjustment is not normally required because Stall Prevention is enabled as a default.
- L3-02Error codeUsed when L3-01 = 1 or 2. 100% is equal to the drive rated current. Decrease the set value if stalling or excessive current occurs with default setting
- L3-03Error codeSets Stall Prevention lower limit during acceleration when operating in the constant power range. Set as a percentage of the drive's rated current
- L3-04Error codeWhen using a braking resistor, use setting "0". Setting "3" is used in specific applications. 0: Disabled - The drive decelerates at the active deceleration rate. If the load is too large or the deceleration time is too short, an ov fault may occur. 1: General Purpose - The drive decelerates at the active deceleration rate, but if the main circuit DC bus voltage reaches the Stall Prevention level, deceleration will stop. Deceleration will continue once the DC bus level drops below the Stall Prevention level. 2: Intelligent - The active deceleration rate is ignored and the drive decelerates as fast as possible without hitting ov fault level. Range: C1-02 / 10. 3: Stall Prevention with Braking Resistor - Stall Prevention during deceleration is enabled in coordination with dynamic braking. 4: Overexcitation Deceleration - Decelerates with the flux level determined by n3-13 (Overexcitation Gain)
- L3-05Error codeSelects the Stall Prevention method to use to prevent drive faults during run. 0: Disabled - Drive runs a set frequency. A heavy load may cause the drive to trip on an oC or oL fault. 1: Decel Time 1 - The drive will decelerate at Decel Time 1 (C1-02) if the output current exceeds the level set by L3-06. Once the current level drops below the L3-06 level, the drive will accelerate back to its frequency reference at the active acceleration rate. 2: Decel Time 2 - Same as setting 1 except the drive decelerates at Decel Time 2 (C1-04). When output frequency is 6 Hz or less, Stall Prevention during run is disabled regardless of the setting in L3-05
- L3-06Error codeEnabled when L3-05 is set to "1" or "2". 100% is equal to the drive rated current. Decrease the set value if stalling or excessive current occurs with the default settings
- L3-10Error codeSets the level of Stall Prevention during deceleration as a percentage of the overvoltage level. If the DC bus voltage rises above the level set in L3-10 during deceleration, the drive will stop. Disabled if L3-04 is set to 2
- L3-11Error codeEnables or disables ov suppression function, which allows the drive to change the output frequency as the load changes, thus preventing an ov fault. 0: Disabled 1: Enabled Note: The frequency reference and motor speed diverge as the regenerative energy begins to flow back into the DC bus and triggers the ov suppression function.
- L3-17Error codeSets the desired value for the DC bus voltage during overvoltage suppression and Stall Prevention during deceleration. Enabled only when L3-04 = 2 or L3-11 = 1
- L3-20Error codeMain Power Circuit Voltage Adjustment Gain
- L3-22Error codeSets the deceleration time used for Stall Prevention during acceleration in Open Loop Vector Control for PM motors. When set to 0, the drive decelerates at the normal deceleration time
- L3-25Error codeSets the ratio between the motor and machine inertia
- L4-07Error codeInsufficient tuning in Open Loop Vector Control Auto-Tuning has not yet been performed (required for Open Loop Vector Control). Insufficient tuning in V/f Control. Gain is too low when using PID control. The frequency reference is assigned to an external source and the signal is noisy. The cable bet
- L5Error codeFault Restart.........................................................................................................................202
- L5-01Error codeSets the counter for the number of times the drive attempts to restart when one of the following faults occurs: GF, LF, oC, ov, PF, rH, rr, oL1, oL2, oL3, oL4, Uv1. Parameter L5-05 determines the how the restart counter is incremented. When the drive operates without fault for 10 minutes, the counter will be reset
- L5-02Error codeSets fault contact (H2-oo = E) activation during automatic restart attempts. 0: Fault output not active. 1: Fault output active during restart attempt
- L5-04Error codeSets the amount of time to wait between performing fault restarts. Enabled when L5-05 is set to 1
- L5-05Error codeFault Reset Operation Selection
- L6-01Error code8: UL3 at RUN - Fault
- L6-02Error codeSets the overtorque/undertorque detection level. 100% is equal to the motor rated current in V/f Control and the motor rated torque in Open Loop Vector Control
- L6-04Error codeSets the response to an overtorque/undertorque condition. overtorque and undertorque are determined by the settings in parameters L6-05 and L6-06. 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 code
- 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

- L8-02Error codeWhen the heatsink temperature exceeds the value set in this parameter, an Overheat Alarm (oH) will occur
