Run/Stop operation and frequency setting through
external signals
Wire both the inverter main power circuit and control circuit.
By setting " "
at ,
a frequency can be set by using a voltage input (terminal 12) for 0 to 10V DC.
By setting " "
at ,
a frequency can be set by using a current input (terminal C1) for 4 to 20mA DC.
In both cases, set ""
at  . |
| Note1: |
When connecting a DC REACTOR (option), remove the jumper bar
from across the terminals [P1] and [P+]. |
| Note2: |
To protect the circuit from overcurrent, install a recommended molded-case circuit breaker (MCCB) or a ground-fault circuit interrupter (GFCI) (equipped with overcurrent protection function) on the inverter's input side (primary circuit). Ensure that the circuit breaker capacity does not exceed the recommended value. |
| Note3: |
Besides the above MCCB or GFCI, install a recommended magnetic contactor (MC) to the inverter if it is necessary to disconnect the inverter from the power supply.
When installing an MC or a solenoid coil near the inverter, connect a surge suppressor in parallel with it. |
| Note4: |
For the wiring of the control circuit, use shielded or twisted
wires. When using shielded wires, connect the shields to G.
To prevent malfunction due to noise, keep the control circuit wiring away from
the main circuit wiring as far as possible (recommended: 10cm or more), and never
set them in the same wire duct. When crossing the control circuit wiring with
the main circuit wiring, set them at right angles. |
| Note5: |
Frequency can be set by connecting a frequency setting device
(external potentiometer) between the terminals 11 and 13 instead of inputting
voltage signal (0 to +10VDC or 0 to +5VDC) between the terminals 12 and 11. |
| Note6: |
(THR) function can be used by assigning code " "
(Trip command) to any of the terminals X1 to X3, or FWD or REV (function code;
