NOTE
 Set Pr.267 and a voltage/current input switch correctly, then input an analog signal in accordance with the setting.
Incorrect setting as in the table below could cause component damage. Incorrect settings other than below can
cause abnormal operation.

 The terminal used for the AU signal input, set "4" in Pr.178 to Pr.184 (input terminal function selection) to assign functions.
NOTE
 Turn the AU signal ON to make terminal 4 valid.
 Make sure that the parameter and switch settings are the same. Different setting may cause a fault, failure or
malfunction.
 Use Pr.125 (Pr.126) (speed setting gain) to change the maximum rotation speed at input of the maximum rotation speed
command voltage (current). At this time, the command voltage (current) need not be input.
Also, the acceleration/deceleration time, which is a slope up/down to the acceleration/deceleration reference speed, is
not affected by the change in Pr.73 setting.
 Changing the terminal assignment using Pr.178 to Pr.184 (input terminal function selection) may affect the other functions.
Set parameters after confirming the function of each terminal.

This could cause component damage to the analog signal output circuit of signal
Voltage input output devices.
(electrical load in the analog signal output circuit of signal output devices increases)
This could cause component damage of the drive unit signal input circuit.

Drive unit
 The speed setting signal inputs 0 to 5VDC (or 0 to 10VDC) to across
the terminals 2-5. The 5V (10V) input is the maximum rotation
speed.
 The power supply 5V can be input by either using the internal power
supply or preparing an external power supply. Prepare an external
power supply to input the power supply 10V. For the built-in power
supply, terminals 10-5 provide 5VDC output.

current input switch in the OFF position changes the terminal 4 to the
voltage input specification. When the AU signal turns ON, the
terminal 4 input becomes valid.
