5.11.4 Adjusting terminals FM/CA and AM
By using the operation panel or parameter unit, terminals FM, CA and AM can be adjusted (calibrated)
to the full scale.
The parameter number in parentheses ( ) is the one for use with the LCD operation panel and the
parameter unit.
NOTES Terminal JOG input specifications (pulse train input or contact input) can be selected with Pr. 291.
When changing the setting value, be careful not to change the terminal JOG input specifications.
(Refer to page 5-282 for pulse train input.)
Connect a meter between the terminals FM and SD after changing the Pr. 291 setting value. When
using the pulse train of FM output (voltage output), be careful that voltage is not added to termi-
nal FM.
A connection cannot be made to the pulse input of a source logic type.
If all parameter clear is performed when selecting the high-speed pulse train output (Pr. 291 = "10,
11, 20, 21, 100"), the terminal FM output can be changed from high-speed pulse train output to
FM output (voltage output), since the Pr. 291 setting value returns to the initial value of "0".
Perform all parameter clear after removing the device connected to the terminal FM.
