(6) Control can be realized with the mechanical system input
The external inputs, such as external start, stop, and speed/position switching is
used to perform the positioning control without using the PLC program.
(7) Easy maintenance
Each QD75 positioning module incorporates the following improvements in
maintainability:
(a) Data such as the positioning data and parameters can be stored on a flash
ROM inside the QD75, eliminating the need of a battery for retaining data.
(Refer to Section 7.1.1.)
(b) Error messages are classified in more detail to facilitate the initial
troubleshooting procedure. (Refer to Section 15.1.)
(c) The module retains 16 error messages and 16 warning messages recently
output, offering more complete error and warning histories.
(Refer to Section 5.6.1.)
(8) Support of intelligent function module dedicated instructions
Dedicated instructions such as the positioning start instruction, and teaching
instruction are provided.
The use of such dedicated instruction simplifies PLC programs.(Refer to Chapter
14.)
(9) Setups, monitoring, and testing through GX Configurator-QP
Using GX Configurator-QP, the user can control the QD75 parameters and
positioning data without having to be conscious of the buffer memory addresses.
Moreover, GX Configurator-QP has a test function which allows the user to check
the wiring before creating a PLC program for positioning control, or test operation
the QD75 using created parameters and positioning data for checking their
integrity.
The control monitor function of GX Configurator-QP allows the user to debug
programs efficiently.
