Software Revised: 07/21/00
This software enhances a GPD515 AC drive with the ability to control the stopped position of the motor’s shaft; the
targeted application is for spindle equipment with automatic tool changers. Orientation is achieved by processing feedback
from a quadrature encoder connected to the spindle shaft. The positioning is based on a defined zero point which may be
the marker pulse from the encoder or a switch.
The enhancements provided include:
Open Loop Vector Operation
The drive may be used without an encoder attached to the motor, the feedback encoder can be used on the spindle.
Closed Loop Vector Operation
The drive may be used with an encoder attached for better low speed control and positioning characteristics. This provides
for better control when using the gearing option. If the motor is not directly coupled to the spindle shaft or gearing is used a
feedback encoder on the spindle is required.
Gearing Ratio
The spindle to motor ratio may be adjusted between 1:10 to 10:1. This option may be used with open loop control,
although closed loop control provides better performance.
Orient Command Input
This input initiates the orientation process and will stop the shaft in the desired position.
Marker Pulse Input
This input is provided through the PG option card. The marker or Z pulse from the encoder may be used to identify actual
position. An external switch may also use this input.
Marker Offset Parameter
This parameter contains the actual stopping position and is measured in the number of counts since the marker pulse.
Oriented Output
This output indicates that the spindle shaft is oriented.
Two monitors are provided to indicate relative position to the marker and the angle relative to the orient position.
(1) ZZZZ refers to the base Model Number of the drive in which the software is installed.
This document is an addendum to the Technical Manual TM4515, listing the effect of this software on the parameters
in the drive and the function descriptions in the manual.
