230V FX Series Positioning Drive Reference Manual
Drive Parameters
The Drive Parameters screen allows you to enter values that relate the FX drive to your
actuator. PCX software and some displays such as EMERSON Motion Control’s T-21 Data
Entry Terminal use these parameters to display familiar user units. (Some examples would
be: in/sec; rpm; steps/rev; ft/min, etc.)

Actuator Polarity
The default setting (+) of this feature provides position or distance increase with CW rotation
of the motor. To change this relationship, press either the left or right arrow key, then press
the Enter key. The screen will show “-”. Now position or distance increases occur with CCW
motor rotation. During the time this change occurs using PCX, the bridge power is turned
“Off” and “On” to accomplish a smooth transition. CW rotation of the motor is defined as you
face the shaft end of the motor as shown below.
Failure to follow safe installation guidelines can cause death or serious injury. Changing
this value is not recommended while the drive is in motion.
