Symbol Name
[13] Potenti- Power supply (+10 VDC) for frequency command potentiometer (Potenti-
ometer ometer: 1 to 5 k )
power Allowable output current: 10 mA
supply
[12] Voltage (1) The frequency is set according to the external analog input voltage.
input
0 to +10 (VDC)/0 to 100 (%) (Normal mode operation)
+10 to 0 (VDC)/0 to 100 (%) (Inverse mode operation)
(2) Used for reference signal (PID process command) or PID feedback
signal.
(3) Used as additional auxiliary setting for various main frequency com-
mands.
* Input impedance: 22 k
* Allowable maximum input voltage is +15 VDC. If the input voltage is +10
VDC or more, the inverter will limit it at +10 VDC.
[C1] Current
(1) The frequency is set according to the external analog input current
input
command.
+4 to +20 (mA DC)/0 to 100 (%) (Normal mode operation)
+20 to +4 (mA DC)/0 to 100 (%) (Inverse mode operation)
(2) Used for reference signal (PID process command) or PID feedback
signal.
(3) Connects PTC thermistor for motor protection.
(4) Used as additional auxiliary setting to various main frequency com-
mands.
* Input impedance: 250
* Maximum allowable input current is +30 mA DC. If the input current
exceeds +20 mA DC, the inverter will limit it at +20 mA DC.
