• The
multi-function outputs can be set to monitor any of the U1 Inverter status items by setting the last
two digits of the parameter number (U1-).
Refer to page 3-12 for a table listing all of these U1 settings.

Note These parameters can be changed during operation.
• For
the output gain, set what multiple of 10 V will correspond to a 100% output of the monitored
item.
• For the output bias, set the amount that the output characteristic will be shifted vertically.
Set this amount as a percentage, with 10 V corresponding to 100%.

• This signal level setting applies to analog outputs 1 and 2 (terminals 21 and 23).
• When
the 0- to
±
10-V signal level is used to output speed values (frequency reference, output frequen
-
cy, or motor speed), positive voltage indicates Inverter output in the forward direction and negative
voltage indicates Inverter output in the reverse direction. (Assuming a bias setting of 0.0.)
