SPEEDS AND RAMP OVERVIEW:
Depending upon your particular system needs, you may find it necessary to adjust minimum to maximum speeds
and ramp time durations.
EXAMPLE # 1:
If your system is a very large Dish or Phased Array with a lot of weight, wind
area and inertia, it may be necessary to increase your maximum ramp up
and ramp down duration. This can be adjusted by using the
“
Ramp Time
”
slide bar in the setup utility. The
“
Ramp Time
”
is the amount of time spent in
each speed increment as it ramps up and down. It may also be suggested
that your maximum speed be lowered to (5) or (6). This can be adjusted by
using the
“
Max Speed
”
slide bar in the setup utility. The
“
Max Speed
”
is the
maximum speed achieved during rotation. The suggested minimum speed
for a very large array would be (3). You can adjust this by using the
“
Min
Speed
”
slide bar in the setup utility. The
“
Min Speed
”
is the minimum
starting speed. However, please keep in mind, The
“
Min Speed
”
must be set
high enough to keep the motor running to provide at least
“1”
degree motion
with the
“
Motor Timeout
”
value.
EXAMPLE # 2:
A system that has minimal weight and wind area, does not necessarily need
the longer ramp up and ramp down duration. There is not as much starting
and stopping torque on motors and bearings. However, it is always your
choice to setup your axis system based upon your particular needs.
STANDARD FACTORY SETTINGS:
These settings have been pre
-
programmed at the factory.
Elevation Axis:
Min Speed = 3 Max Speed = 9 Ramp Time = 3 Rev Delay = 3
Azimuth Axis:
Min Speed = 3 Max Speed = 9 Ramp Time = 3 Rev Delay = 3
Please keep in mind, a little experimentation can help you understand each of these settings and how they
interact within each other.
