EMERSON FX_Drive_230V

Description

A motion control system provides programmable control of speed and  positioning of motors. Controlling motion includes the ability to accelerate  and decelerate, control the velocity and achieve accurate positioning of the  motor shaft. An EMERSON Motion Control System consists of an FX Positioning Drive,  which includes the microprocessor controlled amplifier, a DX (230V) Series  Brushless Servo Motor of correct torque rating, and motor cabling as shown  in Figure 1, “Basic FX Drive,”

Analog and Pulse Inputs 

A 15 pin female “D” 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.

Analog Velocity 

In Analog Velocity Mode the motor shaft velocity is proportional to an  analog voltage applied to the drive. The drive is now strictly a velocity  control and the position loop is disabled. The Analog Velocity Mode Analog  Velocity Mode is selected with a specific setting of front panel DIP switches.

Analog Torque 

In the Analog Torque Mode the motor shaft torque is proportional to the  analog voltage applied to the command connector. The Analog Torque  Mode is selected with a specific setting of front panel DIP switches. If the  motor shaft encounters no resistance and torque is commanded, the motor  will run away.

Pulse/Pulse 

In the Pulse/Pulse Mode (factory default) there are two inputs. One of the  inputs is used for clockwise pulses; the other, counterclockwise pulses.  Supplying a pulse train to the clockwise input moves the motor shaft in a  clockwise direction. Conversely, supplying a pulse train to the  counterclockwise input moves the motor shaft in a counterclockwise  direction. The Pulse/Pulse Mode is selected with specific front panel DIP  switch settings. The FX drive may be commanded to execute Indexes, Jog  and Home moves when in this mode.

Pulse/Direction 

The Pulse/Direction Mode uses two separate inputs (the same as used for  clockwise and counterclockwise inputs), for pulse inputs and direction  inputs. When pulses are applied to the pulse input, the direction of the  motor shaft is controlled by the direction input.

Input/Output Functions 

The FX drive is equipped with eight optically isolated input lines and four  optically isolated output lines. Each input and output line has two screw  terminals associated with it. The first eight pairs of terminals, numbered 1  through 8, are inputs and the last four pairs of terminals, numbered 9  through 12, are outputs. Each of these I/O lines can be configured to  perform a variety of motion control functions. These I/O functions are  assigned to the I/O lines using PCX, user interface software, used to  configure the FX drive. Setup of the I/O functions is explained in the “PCX  Software Setup and Operation” section of this manual.
