MELSEC-Q
1 PRODUCT OUTLINE
(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 QD75MH 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 QD75MH, 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 QD75MH 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 QD75MH 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.
(10) Addition of forced stop function
As forced stop input signal to the connector for external equipment connection is
added, batch forced stop is available for all axes of servo amplifier.
(Refer to Section 12.4.5.)
Selection for whether using "Forced stop input signal" or not can be made with
parameter.
