Tab. 3-9: Input signals (2)
Set Pr. 267 and a voltage/current input switch correctly, then input analog signals in accord-
ance with the settings. Applying a voltage with voltage/current input switch in "I" position
(current input is selected) or a current with switch in"V" position (voltage input is selected)
could cause component damage of the inverter or analog circuit of output devices. Refer to
section 6.16 for details.
Used as power supply when connecting poten-
tiometer for frequency setting (speed setting)
from outside of the inverter.
Rated output voltage: 5V DC
Recommended potentiometer: 1kΩ, 2W linear,
multi turn potentiometer
Inputting 0 to 5V DC (or 0 to 10V) provides the
maximum output frequency at 5V (10V) and
makes input and output proportional. Use Pr.
73 to switch from among input 0 to 5V DC (ini-
tial setting), 0 to 10V DC.
Inputting 4 to 20mADC (or 0 to 5V, 0 to 10V)
provides the maximum output frequency at
20mA and makes input and output propor-
tional. This input signal is valid only when the
AU signal is on (terminal 2 input is invalid).
Use Pr. 267 to switch from among input 4 to
20mA (initial setting), 0 to 5V DC and 0 to
10V DC. Set the voltage/current input switch in
the "V" position to select voltage input (0 to 5V/
0 to 10V).
Terminal 5 provides the common reference
potential (0V) for all analog set point values
and for the analog output signals AM (voltage).
The terminal is isolated from the digital circuit's
reference potential (SD). This terminal should
not be grounded. If local regulations require
grounding of the reference potential note that
this can propagate any noise in the ground
potential to the control electronics, thus
increasing sensitivity to interference.
