7.3 Initial Settings
Refer to section 6.2 and 6.3 for the VS-212DN’s initial settings.
The initial setting are commonly used for the current position detection function, limit switch output
function, and positioning function.
7.4 Parameter Settings
This section explains the parameter settings for the VS-212DN’s positioning function.
When writing the parameters, set ‘1’ to the corresponding bit of the buffer memory address (sequence
mode selection). Set ‘0’ to other bits.
The data written to the buffer memory for data communication with the PLC CPU is loaded to the
VS-212DN when the PLC ready signal is turned ON in sequence mode.
Note:
Some parameters of the VS-212DN are for the limit switch output function and current position
detection.
Setting sequence:
(a) Turn the PLC Ready signal (command 1: 7 bit) OFF.
(b) Set ‘1’ to parameter (PRM) of buffer memory address for sequence mode selection (I/O address: 4).
(c) Write the setting value to buffer memory I/O addresses 12298 to 12311 (12362 to 12375).
(d) Turn the PLC Ready signal ON.
(e) Writing is completed when operation status (status 1: 7 bit) has turned ON.
Important:
Writing to initial setting/parameter setting areas shall not exceed 10000 times.
