Enter -10~+10V or 0~+10V using the voltage (V1) input terminal of the terminal block. If
you enter -10~+10V, you can change the revolution direction of the motor according to
the symbol of the voltage signals.

Set No.06 of the input terminal block group (IN) at Unipolar. Enter the volume
resistance into the V1 terminal by using the voltage output of the external voltage
output or VR output terminal of the inverter control terminal block as follows.
When connecting external power source When connecting internal power source
(2) If you use 0~+10V of the external circuit,
If the volume resistance is connected to the terminal block (IN-01 Freq at 100%) : set
the operating frequency of the maximum voltage input. Set the operating frequency of
which the values set in the input terminal block function group (IN) No. 11 or 15 is 100%.
E.g.1) When IN-01 is 40.00 and the default value is set to IN-16, if 10V is input into the
V1 terminal, operation is at 40.00Hz.
E.g.2) When IN-11 is 50% and the default value is set between IN-01 and IN-16, if 10V is
input into the V1 terminal, operation is at 30.00Hz (50% of max 60Hz).
