L8 Hardware Protection
L8-01 Internal Dynamic Braking Resistor Protection Selection
This parameter selects the dynamic braking resistor protection only when using the 3% duty cycle heatsink mount Yaskawa
braking resistor. This parameter does not enable or disable the general dynamic braking function of the Drive. Do not adjust
this parameter when using any other braking resistors.

L8-03 Overheat Pre-Alarm Operation Selection
The Drive is capable of warning the operator of an impending heatsink over-temperature fault via an OH pre-alarm. The level
at which the pre-alarm will activate is determined by the setting of parameter L8-02. Measurement of the heatsink temperature
