Set existence and logic of a parity and a stop bit length.
Characters are organized for each setting as follows:
LSB MSB
PA2_93
0 1 2 3 4 5 6 7 8 9 10 11
0, 1 Start Data (8 bits) Parity Stop
2 Start Data (8 bits) Stop
3, 4 Start Data (8 bits) Parity Stop (2 bits)
5 Start Data (8 bits) Stop (2 bits)
(4) Response time and communication time over
No. Parameter name Setting range
Default
value
Change
PA2_94 Response time 0.00 to 1.00 [s] (*) 0.00 Always
PA2_95 Communication
time over
0.00 [s]: No detection
0.01 to 9.99 [s]
0.00 Always
(*) Actual response time is set to PA2_94 setting or {time for 3 char amplifier’s processing time},
whichever is longer.
Set the response time and communication time over parameters if needed.
For details, refer to pages 13-34 (response time) and 13-35 (communication time over).
