Part 1 Specification
ڦ Explanation of Function
[1] When the “start trigger” signal is turned ON, gateway information, command responses and axis data will be read
cyclically. (Constant read mode)
[2] When data is set in the gateway control table and the gateway control write signal is turned ON, the gateway control
data (2 words) will be written to the gateway unit at the leading edge of the signal.
When writing data to the request command area or axis data specification area of the gateway, bit 15 of gateway
control dada 0 (MON signal) must be turned “1” (ON) to enable the remote operation.
[3] When data is set in the command request table and the command request write signal is turned ON, the command
request data (6 words) will be written to the gateway unit at the leading edge of the signal.
[4] When data is set in the axis data write table and the axis data write signal is turned ON, the axis control data (64 words)
will be written to the gateway unit at the leading edge of the signal.
[5] If an error occurs during the communication, the FB abort flag turns ON and an error code (FINS command error) is
output to the error code table. When the error reset signal is turned ON, the error will be cleared.
Caution
Do not issue position data write commands successively, because these commands are written to the flash memory area.
The flash memory can be written only so many times (100,000 times).
