Single direction limit: When the upward DEC
limit position is reached, the upward slow speed
area is entered, the system runs at P91.35 and
stops at sudden if the upward limit position is
reached; the upward speed is restricted, but the
downward speed is not restricted. Downward
DEC position limit uses the similar rule.
Bi-directional limit: When the upward/downward
DEC limit position
upward/downward slow speed zone is entered,
which indicates that both the upward and
downward speeds

0: Keep HDO setting same as P06.00 setting.
1: HDO is used as PWM signal for voltage
adjustment output.
P91.37=1: Enable the eddy current control for
tower crane slewing. HDO connects to the
PWM input of the eddy current control module.
You can enable the output voltage of the eddy
current control module to change with the
frequency by setting P91.38–P91.47.
