Configure Parameters
F.017 Discharging Function Enable
This parameter selects whether
the discharging function of DC-
bus voltage is performed or not,
when the 8720MC-RPS unit is
stopped or aborted. When ON is
selected, DC-bus voltage is
discharged when the unit stops.
When OFF is selected, DC-bus
voltage does not discharge.
IMPORTANT:
This parameter is
available from software version
2.00 or later (to be shown on
the parameter F.018).
Parameter Range
OFF, ON
Default Setting
ON
Parameter Type
Requiring the password, configurable only while the unit is normal.

–
Setting this parameter to OFF does not discharge the DC-bus voltage when the 8720MC-RPS unit is stopped or aborted. This results in retaining
an identical voltage in the DC-bus capacitors as the set value of the DC-bus Voltage Reference (U.000).
When the 8720MC-RPS unit is used in Power Regeneration mode (refer to
and
), set this parameter to
OFF, and perform discharging on the inverter unit side. In this case, the discharging time is determined by the inverter unit to be connected.
ATTENTION:
Only qualified electrical personnel familiar with the construction and operation of
this equipment and the hazards involved should change the Factory Parameters. Read and
understand this instruction manual in its entirety before proceeding. Failure to change
parameter values could result in destruction of the equipment, severe bodily injury or loss of life.
ATTENTION:
DC-bus capacitors retain hazardous voltages after input power has been
disconnected. After disconnecting power, wait five minutes for the DC-bus capacitors to
discharge and verify that the DC-bus capacitors are discharged before touching any internal
components. Failure to observe this precaution could result in severe bodily injury or loss of life.

F.019 Selection of Wiring Error (LE) Detecting Function
This parameter selects whether
detecting function of wiring
error (LE) during operation is
used or not. When ON is
selected, wiring errors are
detected when operation is
started. When OFF is selected,
wiring error detection is not
performed.
IMPORTANT:
This parameter is
available from software version
3.00 or later (to be shown on
the parameter F.018).
IMPORTANT:
If other failures
occur, and the main contactor
turns off, an LE error might be
displayed. Set the parameter to
OFF, to mask the LE error.
Parameter Range
OFF, ON
Default Setting
ON
Parameter Type
