5.3 Replace analog output positioning module (AD70/A1SD70) with Q Series
Tip
• The following points must be observed when making a replacement.
Item
No. of occupied slots
No. of occupied I/O
points
Buffer‥memory‥address
Mode setting
LED display
External wiring
*1: Modules occupying two slots cannot be mounted on the Q Series large base unit.
When selecting a Q Series large base to replace modules currently mounted on the same base, the modules must be split
into two bases by adding an extension base.
*2:‥If‥the‥first‥half‥of‥the‥slots‥are‥set‥to‥"open‥0‥points"‥when‥replacing‥the‥existing‥A1SD70,‥set‥the‥parameter‥I/O‥assignment‥
setting as shown below so that the QD73A1 address does not change after replacement.
(1)‥Set‥first‥half‥slots‥to‥"open‥0‥points"
(2) Set last half slots to same address as existing A1SD70 using the head XY setting
When‥replacing‥the‥existing‥AD70,‥set‥the‥first‥half‥slots‥to‥"open‥0‥points".
*3: The program must be revised and added. Refer to the QD731A Positioning Module User's Guide (Details Section).
*4: The mode setting required for positioning changes from hardware switch to parameter I/O assignment switch settings.
Refer to the QD731A Positioning Module User's Guide (Details Section) and set the switches to the same as the A1SD70.
*5:‥Each‥of‥the‥LED‥display‥items‥can‥be‥confirmed‥with‥the‥QD83A1‥I/O‥signals.‥If‥necessary,‥prepare‥external‥lamps,‥etc.,‥to‥
correspond to the LED displays, and display the I/O input signal ON/OFF status for each item.
*6: The base dimensions for mounting QD73A1 are different, so the module mounting position will change.
The connector orientation will be reversed when replacing A1SD70.
