Speed setting by analog input (terminal 2, 4)
4
PARAMETERS
Refer to the following table and set Pr. 73 and Pr. 267.
( indicates main speed setting)
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.

* If the input specification to terminal 4 is changed from the current input (Pr. 267 = "0") to the 0 to 5V or 0 to 10V voltage input (Pr. 267 =
"1 or 2"), calibrate the input with C6. (Refer to page 135)
REMARKS
Turn ON the AU signal to make the terminal 4 function valid. The AU signal is assigned to the terminal AU in the initial setting.
By setting "4" in any of Pr. 178 to Pr. 182 (input terminal function selection), the AU signal can be assigned to other terminals.
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.
The terminal 2 does not accept analog output speed commands when Pr. 561 PTC thermistor protection level ≠ "9999."
NOTE
Make sure that the parameter and switch settings are the same. Different setting may cause a fault, failure or
malfunction.
Always calibrate the input after changing the voltage/input input signal with Pr. 267 and the voltage/current input
selection switch.
Changing the terminal assignment using Pr. 178 to Pr. 182 (input terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.
Setting Causing Component Damage
Operation
Switch setting Terminal input
I (current input) Voltage input
This could cause component damage to the analog signal output circuit of
signal output devices.
(electrical load in the analog signal output circuit of signal output devices increases)
V (voltage input) Current input
This could cause component damage of the drive unit signal input circuit.
(output power in the analog signal output circuit of signal output devices increases)
