<Setting>
There are the following three methods to adjust the speed setting voltage bias and gain.
1) Method to adjust any point by application of a voltage to across terminals 2(1)(3) - 5
2) Method to adjust any point without application of a voltage to across terminals 2(1)(3) - 5
3) Method that does not adjust the bias voltage
(Example) Pr. 903 "speed setting terminal 2 gain"
(Pr. 902 to Pr. 920 can be adjusted in the similar manner.)
<Adjustment procedure> Using the speed setting signal from the control panel (FR-DU04-1) to make speed setting
(1) Power on (monitoring mode) (2) Choose the PU operation mode.
1) Press to make sure that the inverter is in the
PU operation mode. (LED of PU is lit.) (Refer to the
Instruction Manual (basic) for monitor transition.)
2) Set 1 (PU operation mode) in Pr. 79 "operation mode selection". (Refer to page 117.)
Example: To change the external operation mode (Pr. 79 = 2) to the PU operation mode (Pr. 79 = 1)
(3) Read Pr. 903 to display the currently set gain speed.
