(e) Acceleration/deceleration processing
Two acceleration/deceleration processing methods are provided:
trapezoidal acceleration/deceleration and S-curve acceleration/deceleration.
The acceleration/deceleration curve can be selected according to the
machine characteristic.
(2) Synchronous control
The synchronous control and electronic cam control can be performed.
(3) Mark detection function
The mark detection to latch any data by the external command signal [DI1 to DI4]
can be performed.
(4) High maintainability
Maintainability is enhanced in the QD77GF.
(a) Data retention without battery
Data such as the positioning data and parameters can be stored in the flash
ROM inside the QD77GF. This feature allows the module retain the data
without a battery.
(b) Module error collection function
The QD77GF notifies error details to the PLC CPU when an error occurs.
Storing the error information in the PLC CPU allows the user to check the
error from the programming tool even after the module is powered off or
reset.
(5) Setting, monitoring, and testing through GX Works2
Parameters and positioning data for the QD77GF can be set using GX Works2
(Simple Motion Module Setting).
Moreover, using the test function of GX Works2 (Simple Motion Module Setting),
users can check the wiring status and the validity of the preset parameters and
positioning data by performing test operation before creating a program for
positioning control.
The control monitor function of GX Works2 allows user to debug programs
efficiently.
The servo parameters can be set easily by using the GX Works2 in combination
with the MR Configurator2.
(6) Forced stop function
The batch forced stop is available for all axes of servo amplifier by the forced
stop signal.
"Valid/Invalid" of the forced stop input signal can be selected by the parameters.
