1.6.4
Regenerative brake duty
(A700)
Do not connect an electronic magnetic brake. When using
an external, large thermal-capacity discharge resistor for
regenerative brake in
, always remove the jumper
(between terminal PR and PX) of the built-in discharge
resistor for regenerative brake.
1.6.5
I/O signal
(common)
The I/O devices may be damaged if a voltage higher than
the value indicated on page 28 is applied to the inverter I/O
signal circuits or reverse polarity is used. Especially check
the wiring to prevent the frequency setting potentiometer
from being connected incorrectly to short terminals 10 (E)-5.
1.6.6
Connection to a large-capacity power supply
(common)
The inverter input current varies with the impedance of the
power supply. (i.e. the power supply's power factor varies.)
When the power supply capacity is 1000KVA or more for
(500kVA or more for
), insert a
power factor improving reactor. (Refer to page 507 for
details)
A700 E700 D700
Across P/+ and PR terminals, connect only an external regenerative brake discharge resistor.
A700
common
Do not apply a voltage higher than the permissible voltage to the inverter I/O signal circuits.
common
When connecting the inverter near a large-capacity power supply, insert a power
factor improving reactor.
