Torque Detection Sets the overtorque detection level. 100% is equal to the motor rated
L6-02
Level 1 current.
Torque Detection Sets the length of time an overtorque condition must exist before
L6-03
Time 1 Torque Detection is triggered.
Internal Dynamic Selects the Braking resistor when using a 3% duty cycle heatsink
Braking Resistor mounted braking resistor. This parameter does not enable or disable
L8-01 Protection the braking transistor of the drive.
Selection (ERF 0: Resistor overheat protection disabled
type) 1: Resistor overheat protection enabled
Selects the detection of input current phase loss, power supply voltage
Input Phase Loss imbalance, or main circuit electrolytic capacitor deterioration.
L8-05 Protection 0: Disabled
Selection 1: Enabled
Note: This parameter is disabled in 200 V single-phase drives.
Controls the heatsink cooling fan operation.
Heatsink Cooling 0: Fan On-Run Mode - Fan will operate only when the drive is running
L8-10 Fan Operation and for 60 seconds after stop.
Selection 1: Fan always on - Cooling fan operates whenever the drive is
powered up.
Ambient
Used to input the ambient temperature. This value adjusts the drive
L8-12 Temperature
oL2 detection level.
Setting
Selects the software current limit function. Typically no adjustment
Soft CLA is required.
L8-18
Selection 0: Disabled
1: Enabled
Selects the installation type:
0: IP20/IP00 Drive
L8-35 Installation
1: Side-by-Side Mounting
<3> Method Selection
2: NEMA Type 1 Drive
3: Finless Drive or External Heatsink Installation
Provides protection to the IGBTs by reducing the carrier frequency
at low speeds.
0: Disabled
1: Enabled below 6 Hz
2: Enabled for the whole speed range
Carrier Frequency
L8-38
Reduction
<1> When enabled, the drive stops accelerating when it exceeds the value of L3-02, Stall Prevention Level. The drive decelerates after 100 ms and
begins accelerating again after restoring the current level.
<2> Default setting value is 120% when C6-01 is set to 1 (ND) and 150% when C6-01 is set to 0 (HD).
<3> This parameter is not reset to the default value when the drive is reinitialized using A1-03.
