OPERATION
1. Introduction
The following secUons- outline-how to operate the LE-Dri vee
Although every effort has been made to provide enough information
to successfully (and easily) operate the LE-Drive, there are
bound to be ommissions (and, ugh, errors). If you find any
errors or you think that something should be added to the manual,
call Compumotor or one of its representatives to get the
information you need.
To check to see if the LE-Dr.ive is operating at all, refer to the
"111itial Functional Check" section of this manual.
2. Visual Indicators
-
There is one bicolor STATUS LED (light emitting diode) indicator
on the indexer connector end of the LE-Drive.
The STATUS LED is green any time the LE-Drive power supply is
operational and no FAULT condition has been detected. If the
STATUS LED is not lllum1nat.ed, AC power is not applied or there
is a drive failure (check the fuse~
The STATUS LED is red any time the LE-Drive shuts itself down
because of an internally sensed error condition. This is most
likely to occur as a result of over heating (the LE-Drive has a
built in temperature sensor). A FAULT may be cleared by
providing improved drive cooling and/or temporarily removing the
AC power.
3. Indexer Inputs
Thll! indexer inputs provide the normal control signals for the LE-
Drive. Following is a functional description of how each is
used.
A. Step Input
The STEP input causes the motor to be incremented one microstep.
By applying STEPs at various rates the motor is made to rotate at
proportional velocities. STEP pulses applied first slowly, and
then more quickly has the effect of accelerating the motor.
Accelerating the motor too quickly can cause the motor to stall.
The motor will STEP in the direction determined by the DIRECTION
inlput.
~ Direction Input
The DIRECTION input (a. you might gues.) controls the direction
of rotation of the aotor. When this 8ignal is not activated the
