B.2 Parameter Table 178 SIEP C710606 33A OYMC AC Drive – J1000 User Manual No. Name Description Range Def. Mode Addr. Hex Pg. L1-02 Motor Overload Protection Time Sets 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. 0.1 to 5.0 1.0 min O 481 103 L1-13 Continuous Electrothermal Operation Selection Determines whether or not to hold the electrothermal value when the power supply is interrupted. 0: Disabled 1: Enabled 0, 1 1 O 46D 103 L2:
Momentary Power Loss Use L2 parameters to configure drive functions for momentary power loss conditions. L2-01 Momentary Power Loss Operation Selection Enables 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 Power Loss Ride-Thru Time. 2: CPU Power Active - Drive will restart if power returns as long as the CPU is working. 0 to 2 0 O 485 103 L3: Stall Prevention Function Use L3 parameters to configure the Stall Prevention function.
L3-01 Stall Prevention Selection during Acceleration Selects the Stall Prevention method used to prevent excessive current during acceleration. 0: Disabled - Motor accelerates at active acceleration rate. The motor may stall if load is too heavy or accel time is too short. 1: General Purpose - When output current exceeds L3-02 level, acceleration stops. Acceleration will continue when the output current level falls below the L3-02 level. 0, 1 1 O 48F 104 L3-02 Stall Prevention Level during Acceleration Used when L3-01 = 1. 100% is equal to the drive rated current. Decrease the set value if stalling or excessive current occurs with default setting.
0 to 150 O 490 104 L3-04 Stall Prevention Selection during Deceleration When using a braking resistor, use setting "0". 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. 4: Overexcitation Deceleration - Decelerates with the flux level determined by n3-13 (Overexcitation Gain).
0, 1, 4 1 S 492 105 L3-05 Stall Prevention Selection during Run Selects 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. 0 to 2 1 O 493 105 L3-06 Stall Prevention Level during Run Enabled 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. Upper level is determined by C6-01 and L8-38. 30 to 150 O 494 106 L4: Frequency Detection Use L4 parameters to configure frequency detection operation. L4-01 Speed Agreement Detection Level These parameters configure the multi-function output (H2- 01 = 2, 4, 5) settings "Speed Agree 1", "Frequency Detection 1," and "Frequency detection 2".
0.0 to 400.0 0.0 Hz O 499 106 L4-07 Frequency Detection Conditions 0: No detection during baseblock. 1: Detection always enabled. 0, 1 0 O 470 106 L5: Fault Reset Use L5 parameters to configure Automatic Restart after fault. L5-01 Number of Auto Restart Attempts Sets the counter for the number of times the drive attempts to restart when one of the following faults occurs: oC, ov, PF, rH, oL1, oL2, oL3, Uv1. When the drive operates without fault for 10 minutes, the counter will be reset. 0 to 10 0 O 49E 107
