When F65 is 1: It is increased as much as the step frequency set as F66 at the rising edge of multi-
function input set as UP and when up-down is defined, it saves frequency at the falling edge. It is
decreased as much as the step frequency set as F66 at the falling edge of rising edge of multi-function
input set as DOWN and when up-down is defined, it saves frequency as the falling edge. In this case,
while multi-function input set as UP or DOWN is defined, if a stop command is given, the previous falling
edge value is saved and if multi-function input is not defined, the present frequency is not saved. The
accel/decel time is the same as when set as “0”.
When F65 is 2: It is increased as much as step frequency set as F66 at the rising edge of multi-function
input set as UP and if it is activated for 3 seconds, it operates as it was set as “0”. It is decreased as
much as the step frequency set as F66 at the rising edge of multi-function input set as DOWN. If it is
activated for 3 seconds, it operates as it was set as “0” and the accel/decel time is the same as when set
as “0”.
