Un\G122 to Un\G137)
(1) Set the varying rate range of the digital output value for each channel.
(2) To make the setting valid, the operating condition setting request (Y9) must be
turned ON/OFF. (Refer to Section 3.3.2.)
(3) The setting range is -65536 to 65535 (-6553.6 to 6553.5%). Set the value in
0.1%/s increments.
Example) When setting the rate alarm upper limit value to 30%/s, store 300 into
the buffer memory.

POINT
The channel where the value outside the above setting range has been written
results in an error, the error code is stored into the Error code (buffer memory
address 19: Un\G19), the error flag (XF) turns ON, and the rate alarm is executed
at the pre-error setting.
