230V FX Series Positioning Drive Reference Manual
Modes of Operation
There are five modes of operation available on the basic drive. These modes are Indexing,
Analog Velocity, Analog Torque, Pulse/Pulse and Pulse/Direction. FX drives are shipped
from the factory in the Indexing/Pulse-Pulse mode.
Indexing
The primary operating mode of the FX drive is the Indexing mode. The Indexing mode is
available at all times and is independent of any alternative operating mode switch settings.
The basic drive provides up to thirty-two different moves or “indexes” that can be pre-
programmed using PCX user interface software. All parameters are stored in the FX drive’s
non-volatile memory (NVM). Each index is a complete and unique motion sequence.
Commands to start these indexes plus other commands such as Stop, Jog and Home may be
input from a Programmable Logic Controller (PLC), an operator interface or through serial
communications. Setup of the I/O functions is fully explained in “Software Setup and
Operation” on page 67 in this manual. Serial commands are listed in the FX Drives Serial
Commands Manual (P/N 400255-00).

Analog and Pulse Inputs
A 15-pin female D-subminiature type connector is provided on the FX drive for pulse and
analog inputs.
The pulse input allows direct control of motor velocity and position from a series of pulses.
The velocity of the motor is determined by the rate at which the pulses are received. The
position is determined by the number of pulses received.
An analog input provides direct control of motor shaft velocity or available torque. Velocity
or torque is proportional to the applied voltage. The input can be Ø to ±10 VDC.
