PRACTICAL CIRCUITS
4.1.3
The inverter equipped with magnetic contactor on primary side (with high-duty
brake resistor)
(A700)
22K or less
0.4K to 15K
*1
This magnetic contactor is provided to prevent an automatic restart when power is restored after a power failure. Use the start
signal (ON or OFF of STF, STR) to make a start or stop.
*2
When the power supply is 400V class, install a step-down transformer.
*3
Set [
Pr. 75
= 1] "Reset input is enabled only when the fault occurs" to disable resetting of the inverter during normal operation. (If
the inverter is reset during normal operation, the motor coasts to a stop. This setting is to prevent the inverter from resulting in
an alarm if the motor is still coasting when the inverter has returned from the reset status.)
*4
When using an external brake resistor or brake unit, remove the jumper from across PR-PX.
(
7.5K or less only. Not available for
.
Do not use PR and PX terminals for the
. Do not remove the jumper connected to terminal PR and PX.)
