Fuji Electric frenic mini series - Basic Wiring Diagram; Keypad Operation

Wiring Diagram
Basic wiring diagram
The following diagram is for reference only. For detailed wiring diagrams, refer to the Instruction Manual.
Keypad operation
Operation by external signal inputs
Run/Stop operation and frequency setting on the keypad
[Wiring method]
1. Connect the inverter main power circuit only.
[Operation method]
1. Run/Stop ... Press or key on the keypad.
2.
Setting frequency ... Turn the potentiometer on the keypad.
Note 1: 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.
Note 2: 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.
Run/Stop operation and frequency setting through external signals
[Wiring method]
1.
Connect both the inverter main power circuit and control circuit.
2. At first, set at " : external signal." Next, set at " :
voltage input (terminal 12) (0 to +10V DC)," at " : current input
(terminal C1) (+4 to 20mA)," or at " ".
[Operation method]
(1) Run/Stop ... Short-circuit the terminals FWD and CM to run, and
open the circuit to stop.
(2) Setting frequency ... Voltage input (0 to +10V DC); Current input (+4
to 20mA DC)
Note 1: Before connecting a DC REACTOR (option), remove the jumper
bar between the terminals [P1] and [P+]. For the single-phase
100V series, the reactor connection terminals are different. For
details, refer to the Instruction Manual.
Note 2: 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.
Note 3: 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.
Note 4: Frequency can be set by connecting a frequency setting device
(external potentiometer) between the terminals 13, 12, and 11
instead of inputting voltage signal (0 to +10V DC or 0 to +5V DC)
between the terminals 12 and 11.
Note 5: Use shielded or twisted cables as the control signal wires, and
connect the shielded cables to the ground. To prevent
malfunction due to noise, keep the control signal wires away
from the main circuit wires as far as possible (10cm or more
recommended), and avoid storing them in the same wire duct.
When they need to cross with each other, lay them at right
angles.
Note 6: (THR) function can be used by assigning code " " (Trip
command) to any of the terminals X1 to X3, FWD or REV
(function code; to , , or ).
