When using terminals
PC-SD as a 24VDC
power supply, take care
not to short across
terminals PC-SD.
Contact input common (Sink*)
24VDC power supply/ max. 100mA load current
Contact input common(Source*)
*(Common for external power supply transistor)
Frequency setting signal (Analog)
*3. Terminal input specifica-
tions can be changed
by analog input specifi-
cations
*4 The input area can be set
via Parameter (Pr. 267).
Set the voltage/current
input switch in the "V"
position to select voltage
input (0 to 5V/0 to 10V)
and "I" (initial value) to
select current input
(0/4 to 20mA.)
*5 It is recommended to use a 1 kΩ, 2 W
potentiometer when the frequency
setting signal is changed frequently.
CAUTION
To prevent a malfunction due to noise, keep the signal cables more than 10cm away from the power cables.
After wiring, wire offcuts must not be left in the inverter. Wire offcuts can cause an alarm, failure or malfunction. Always keep the
inverter clean. When drilling mounting holes in a control box etc., take care not to allow chips and other foreign matter to enter the
inverter.
Set the voltage/current input switch in the correct position. An incorrect setting may cause a fault, failure or malfunction.
