Internal Dynamic
Braking Resistor
Protection
Selection (ERF
type)
Selects the Braking resistor when using a 3% duty cycle heatsink
mounted braking resistor. This parameter does not enable or disable
the braking transistor of the drive.
0: Resistor overheat protection disabled
1: Resistor overheat protection enabled

Input Phase Loss
Protection
Selection
Selects the detection of input current phase loss, power supply voltage
imbalance, or main circuit electrolytic capacitor deterioration.

<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.

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.
