When the following settings are made for channel 1 with the output range -10 to 10V set to it
• "CH1 Scaling enable/disable setting": "0: Enable"
• "CH1 Scaling upper limit value": 12000
• "CH1 Scaling lower limit value": 4000

• When using the scaling function, the digital value before scaling can be set to a value out of the range of the
scaling upper and lower limit values (dotted line area in the I/O characteristics). However, use the scaling
function within the range of the analog output practical range (solid line area in the I/O characteristics). If the
value is out of the analog output practical range, the maximum resolution and accuracy may not fall within
the range of performance specifications.
• The default digital value "0" may not be appropriate depending on the scaling function setting. Especially in
the above examples, an out-of-range digital value error (error code: 060H) occurs if CH Output enable/
disable flag (RY10 to RY17) is turned on with the digital value being "0". Therefore, set an appropriate digital
value within the scaling range before turning on CH Output enable/disable flag (RY10 to RY17).
