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 

 

Polarity Axis:  

Min Speed = 1  Max Speed = 5  Ramp Time = 3  Rev Delay =3  

  

POLARITY WARNING: DO NOT DRIVE THE POLARITY AXIS FASTER THAN SPEED (5). Limit switch     

damage can occur. 

 

 

Please keep in mind, a little experimentation can help you understand each of these settings and how they       

interact within each other.
