Drive Setup - Preliminary Data
Before you set up your FX drive using PCX, you need to know some specific details about
your system and make some calculations based on your system configuration. Be sure you
know the following system details before starting:
1. System configuration - If you are using a gear reducer, leadscrew or belt and
pulley, you will need to know the ratio of motor turns per actuator turns. For example, a 10:1
gear reducer, a 2:1 belt and pulley, or a 0.2 in/rev lead screw.
2. User units - Units of measure (distance and velocity) your system operates with;
Distances - inches (in), feet (ft), degrees (deg), etc.; Velocities - inches per second (ips), feet
per minute (fpm), degrees per second (dps), etc.
3. Mechanical limitations of your system - distance limits, torque limits and
maximum safe speed (velocity in user units).
For example, in Figure 61: "FX Drive System Example" on page 79 you would need to know
the following information; gear reducer ratio, lead screw ratio, user units that you want the
system to operate with, distance the table can travel and velocity at which the table can safely
travel.
