Meter adjustment 2 when the inverter is at rest (adjustment by setting  () to : Fixed output 2)
This function is useful especially in adjusting the current monitor, and the levels of items (a) to (d) in the list on the
previous page are adjusted, as described below.
(a) :The output voltage is 54% of the voltage at FM/AM when the frequency is at the maximum level ().
(b) :The output voltage at FM/AM-CC reaches 100% when the reading on the operation panel is 100%.
(c) : The output voltage at FM/AM-CC reaches 100% when the reading on the operation panel is 81%.
(d) :The output voltage at FM/AM-CC reaches 100% when the reading on the operation panel is 135%.
Meter adjustment 3 when the inverter is at rest (adjustment by setting  () to : Fixed output 3)
This function is useful especially in adjusting the torque monitor, and the levels of items (a) to (d) in the list on the
previous page are adjusted, as described below.
(a) :The output voltage is 40% of the voltage at FM/AM when the frequency is at the maximum level ().
(b) :The output voltage at FM/AM-CC reaches 100% when the reading on the operation panel is 74%.
(c) : The output voltage at FM/AM-CC reaches 100% when the reading on the operation panel is 60%.
(d) :The output voltage at FM/AM-CC reaches 100% when the reading on the operation panel is 100%.
