Mitsubishi D700 inverter quick set-up guide
Mitsubishi inverters are factory set for EXTernal control.
When a START signal is connected across the STF-PC input terminals the inverter will run to a
speed set by a potentiometer on terminals 10, 2, and 5, see below.
When START is pressed the FWD run status LED should flash and the Hz display increase.
To change parameters
1) Change to PU operation ( )
2) Scroll to select the parameter
3) Press SET to display the current value
4) Scroll to change the value
5) Press SET button to write the value

Pr.14 = 1 for clean water pumps, fans etc
For better motor and system efficiency -
Pr.60 = 9 for Energy saving control selection

Check list :-
The EXT LED should be ON (PU is Parameter Unit mode for set-up).
Use the correct common for the control signals, PC is the default, not SD.
The inverter will not run if the MRS signal is connected.
Control mode Parameter Pr.79 is set to either 0 or 2 for EXT control.

Alarm History
The previous EIGHT alarms are retrievable using the keypad
To access the Alarm menu
Press the mode button twice - E--- is displayed
Scroll through the alarm History
Press SET to read the Hz, Amps, Volts and hrs ON for each
alarm.
The inverter PC software “FR-Configurator V3” supports
diagnosis and setup for FR-D700.
General causes of alarms
For full information on alarm codes, please refer to the installation manual for the specific inverter.
Inverter Overload
Over current (OC1, OC2), and transistor thermal alarms (THT) are caused by too much current flowing in the inverter transistor circuits.
CHECK - Monitor the current during start-up and running.
1. E.OC1 Immediate over-current - output short-circuit or already rotating motor.
2. E.OC1 Over-current after 1 second - stalled motor, jammed motor, high friction,
Pr.14 may be incorrectly set to 1, torque boost (Pr.0) set too high
3. E.OC1 Overload after half speed - high inertia, acceleration (Pr.7) too fast, torque
level too low as Pr.14 may be set to 1.
4. E.OC2 Overload at steady speed - high motor current, sudden load increase,
incorrect pump rotation, single-phasing of the output.
Motor thermal overload
Pr.9 is set to the motor rated current. The inverter calculates the level of current at reduced speeds that will cause a temperature build-up in
the motor. If the E.THM alarm occurs but the motor is NOT hot, then the value can be increased to avoid nuisance tripping.
CHECK - Pr.0 - should be set as low as possible, while still allowing the motor to start
Pr.14 - can be set to 1 for clean water pumps
For a high load and low speed operation extra ventilation on the motor and Pr.71=1 can be used.
