Name Description Setting PageL7-01(4A7H) Forward Torque LimitSets the torque limit value as a percentage of the motor rated torque. Four individual quadrantscan be set.Default: 200%Min: 0%Max: 300%294L7-02(4A8H) Reverse Torque LimitDefault: 200%Min: 0%Max: 300%294L7-03(4A9H)Forward Regenerative TorqueLimitDefault: 200%Min: 0%Max: 300%294L7-04(4AAH)Reverse Regenerative TorqueLimitDefault: 200%Min: 0%Max: 300%294L7-06(4ACH)Torque Limit Integral TimeConstantSets the integral time constant for the torque limit.Default: 200 msMin: 5 msMax: 10000 ms294L7-07(4C9H)Torque Limit Control MethodSelection during Accel/Decel 0: Proportional control (changes to integral control at constant speed). Use this setting whenacceleration to the desired speed should take precedence over the torque limit.1: Integral control. Set L7-07 to 1 if the torque limit should take precedence.Default: 0Min: 0Max: 1295L7-16(44DH) Torque Limit Process at Start0: Disabled1: EnabledDefault: 1Min: 0Max: 1295No. (Addr.) Name Description Setting PageL8-01(4ADH)Internal Dynamic Braking ResistorProtection Selection (ERF type) 0: Resistor overheat protection disabled1: Resistor overheat protection enabledNote: This parameter is not available in models CIMR-A4A0930 and 4A1200.Default: 0Min: 0Max: 1295L8-02(4AEH) Overheat Alarm LevelAn overheat alarm will occur if the heatsink temperature exceeds the level set in L8-02.Default: <6>Min: 50CMax: 150C295L8-03(4AFH)Overheat Pre-Alarm OperationSelection0: Ramp to stop. A fault is triggered.1: Coast to stop. A fault is triggered.2: Fast Stop. Decelerate to stop using the deceleration time in C1-09. A fault is triggered.3: Continue operation. An alarm is triggered.4: Continue operation at reduced speed as set in L8-19.Default: 3Min: 0Max: 4296L8-05(4B1H)Input Phase Loss ProtectionSelectionSelects the detection of input current phase loss, power supply voltage imbalance, or maincircuit electrolytic capacitor deterioration.0: Disabled1: EnabledDefault: 1Min: 0Max: 1297L8-07(4B3H)Output Phase Loss ProtectionSelection 0: Disabled1: Enabled (triggered by a single phase loss)2: Enabled (triggered when two phases are lost)Default: 0Min: 0Max: 2297L8-09(4B5H)Output Ground Fault DetectionSelection 0: Disabled1: EnabledDefault: <6>Min: 0Max: 1297L8-10(4B6H)Heatsink Cooling Fan OperationSelection 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.)Default: 0Min: 0Max: 1297L8-11(4B7H)Heatsink Cooling Fan Off DelayTime Sets a delay time to shut off the cooling fan after the Run command is removed when L8-10 = 0.Default: 60 sMin: 0 sMax: 300 s298L8-12(4B8H) Ambient Temperature SettingEnter the ambient temperature.
