Keypad operation
■
Run/Stop operation and frequency setting on the keypad
[Wiring procedure]
(1) Wire the inverter main power circuit.
[Operation method]
(1) Run/Stop: Press or key.
(2) Setting frequency: Set the frequency with and keys.
Note1: When connecting a DC REACTOR (DCR option), remove the
jumper bar from across the terminals [P1] and [P (+)].
Note2: Install a recommended molded-case circuit breaker (MCCB) or a
ground-fault circuit interrupter (with an overcurrent protection
function) in the primary circuit of the inverter to protect wiring. At
this time, ensure that the circuit breaker capacity is equivalent to
or lower than the recommended capacity.
Note3: Install a magnetic contactor (MC) for each inverter to separate the
inverter from the power supply, apart from the MCCB or GFCI,
when necessary.
Connect a surge killer in parallel when installing a coil such as the
MC or solenoid near the inverter.
Note4: (THR) function can be used by assigning code "9" (external alarm)
to any of the terminals X1 to X5, FWD or REV (function code; E01
to E05, E98, or E99).
■
Operation by external signal inputs
■
Run/Stop operation and frequency setting through external signals
[Wiring procedure]
(1) Wire both the inverter main power circuit and control circuit.
(2) Set (external signal) at function code . Next, set (voltage input
(terminal 12) (0 to +10V DC)), (current input (terminal C1) (+4 to
20mA DC)), or other value at function code .
[Operation method]
(1) Run/Stop: Operate the inverter across terminals FDW and CM short-
circuited, and stop with open terminals.
(2) Frequency setting: Voltage input (0 to +10V DC), current input (+4 to
20mA DC)
Note1: When connecting a DC REACTOR (DCR option), remove the
jumper bar from across the terminals [P1] and [P (+)].
Note2: Install a recommended molded-case circuit breaker (MCCB) or a
ground-fault circuit interrupter (with an overcurrent protection
function) in the primary circuit of the inverter to protect wiring. At
this time, ensure that the circuit breaker capacity is equivalent to
or lower than the recommended capacity.
Note3: Install a magnetic contactor (MC) for each inverter to separate the
inverter from the power supply, apart from the MCCB or GFCI,
when necessary.
Connect a surge killer in parallel when installing a coil such as the
MC or solenoid near the inverter.
Note4: (THR) function can be used by assigning code "9" (external alarm)
to any of the terminals X1 to X5, FWD or REV (function code; E01
to E05, E98, or E99).
Note5: Frequency can be set by connecting a frequency-setting device
(external potentiometer) between the terminals 11, 12 and 13
instead of inputting a voltage signal (0 to +10V DC, 0 to +5V DC
or +1 to +5V DC) between the terminals 12 and 11.
Note 6: For the control signal wires, use shielded or twisted wires.
Ground the shielded wires. To prevent malfunction due to noise,
keep the control circuit wiring away from the main circuit wiring as
far as possible (recommended: 3.94inch(10cm) or more). Never
install them in the same wire duct.
When crossing the control circuit wiring with the main circuit wiring,
set them at right angles.
