- L1Error codeMotor Protection Functions ..................................................................................................203
- L1-01Error codeMotor Protection Function Selection
- L1-02Error codeSets the motor thermal overload protection (oL1) time. A larger L1-02 time will increase the time for an oL1 fault to occur. This parameter does not typically require adjustment. Should be set in accordance with the overload tolerance of the motor
- L1-03Error codeSets operation when the motor temperature analog input (H3-02/10 = E) exceeds the oH3 alarm level. 0: Ramp to Stop 1: Coast to Stop 2: Fast-stop using C1-09 3: Alarm Only (“oH3” will flash)
- L1-04Error codeSets stopping method when the motor temperature analog input (H3-02/10 = E) exceeds the oH4 fault level. 0: Ramp to Stop 1: Coast to Stop 2: Fast-stop
- L1-05Error codeThis parameter adjusts the filter on the motor temperature analog input (H3-02 or H3-10 = E). Increase to add stability, decrease to improve response
- L1-22Error codeSets the time constant for reducing the sensitivity level when detecting leakage current. Set in seconds and used when operating at constant speed. Note: This parameter is available only when C6-02 is set to B. To display this parameter, first set C6-02 = B
- L1-23Error codeSets the time constant for reducing the sensitivity level when detecting leakage current. Set in seconds and used during acceleration and deceleration operation. Note: This parameter is available only when C6-02 is set to B. To display this parameter, first set C6-02 = B
- L2-01Error codeEnables and disables the momentary power loss function. 0: Disabled - Drive trips on (Uv1) fault when power is lost. 1: Power Loss Ride-Thru Time - Drive will restart if power returns within the time set in L2-02. 2: CPU Power Active - Drive will restart if power returns as long as the CPU is working
- L2-03Error codeSets the minimum wait time for residual motor voltage decay before the drive output reenergizes after power loss Ride- Thru. If L2-03 is greater than L2-02, operation resumes after the time set in L2-03
- L2-04Error codeSets the time for the output voltage to return to the preset V/ f pattern during Speed Search
- L2-05Error codeUv detection voltage
- 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). 7: Overexcitation Deceleration 3 - Applies more braking power than normal overexcitation deceleration. Yaskawa recommends extra caution due to the heavy load on the motor
- 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
- L3-11Error 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
- L3-24Error codeSets the time needed to accelerate the uncoupled motor at rated torque from stop to the maximum frequency. Setting the drive capacity to parameter o2-04 or changing E2-11 will automatically set this parameter for a 4-pole motor
- L3-25Error codeSets the ratio between the motor and machine inertia
- L4-08Error code0: Match speed with the soft-starter output 1: Match frequency reference and motor speed Note: In V/f Control, the drive ignores the value set to L4-08 and refers to the soft-starter output to determine whether a speed agree situation has been reached
- L5Error codeFault Restart.........................................................................................................................219
- 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, oH1, ov, PF, rH, rr, oL1, oL2, oL3, oL4, STo, 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
