4.1.3 Motion
Clicking on the Motion button will bring up the Motion menu where one of several operating modes
may be selected. Digital Positioning (Pulse/Dir), Velocity (Oscillator), SCL, and Hub are the modes
available for the -S drives.
Digital Positioning Mode
Pulse Input Mode is for systems where the position of the motor is determined by a digital input
signal in the form of pulses.
The three modes available are:
Pulse and Direction:
A signal such as that generated by a step motor controller is used. In this
mode, the frequency of the pulses fed into one input determines the speed of the motor. Direction
of rotation is determined by a signal fed into another input. Either an ON or OFF signal can be
configured to represent clockwise motion.
CW and CCW Pulse:
The drive has two inputs allocated to this feature and the motor will move
CW or CCW depending on which input the pulse is fed into.
A & B Quadrature:
This is sometimes called “Slave Mode.” Signals fed to the drive from a mas-
ter encoder control the movement of the motor. The encoder may be mounted on a shaft on the
machine or can be another motor in the system. With quadrature input, it is possible for a number
of motors to be “daisy chained” together with the encoder output signal from each drive being fed
into the next one.
For all the Pulse Input modes you will need to determine a value to enter into the Electronic Gear-
ing Box, an explanation on how to do this is given in the next section.
