Set parameter L3-04 = “0” or “3” to disable stall prevention during deceleration.
Set parameter L8-01 to “1” to enable overheat protection when using a heatsink-mounted braking resistor
option.
Set L8-01 = “0” for other braking resistor types.
Set parameter L3-04 = “3” to generate the shortest possible deceleration time.
