Connect alternating power supply.
Connect three- phase motor.
Remove the short bar between PD and P, connect optional power factor reactor(DCL)
Connect optional External braking resistor. ( Installed on 5.5kW to 15kW )
Connect optional Regenerative braking unit (BRD).
It is earth terminals of inverter case.
It is common terminal of frequency command signal(O, O2, OI)
and analogue output, AM, AMI. Don"t earth.
It is the DC+10V power for terminals.
When inputting DC 0 ~10V, it is maximum frequency on 10V.
When maximum frequency is expected to be on being less then 10V,
set with A014
When inputting DC 0 ~ 10V, this signal is added to frequency
command of O or OI terminal.
When inputting DC 4 ~20mA, 20mA is maximum frequency.
When only terminal is ON, this input signals is effective.
(voltage)
Output one selected from monitor item, output frequency, output
current, torque, output voltage, input electric power, electric thermal
rate, LAD frequency
Output the output frequency with digital besides above monitor.
It is DC24V power for connection input signal. When selecting source
logic, it's connection input common
The common terminal is FW terminal, 1-8 terminal, TH terminal,
FM terminal, Don't earth.
Change sink type and source type by short bar on control terminals.
P24-PLC : Sink type CM1-PLC : Source type
common
About FW signal, ON is Forward and OFF is stop command.
Select 8 function from 44 functions, and divide between 1 terminal
and 8 terminals.
Select 5 function from 22 functions, and divide between 1 terminal
and 5 terminals.
It is common terminal of alarm output terminal
Assign output function. Output is c contact
When a Thermistor connected to terminals TH and CM1, the inverter
checks for over-temperature and will cause trip event and turn off
output to motor.
