Main Circuit Connection Diagram - YASKAWA A1000 Series Quick Start Manual

3 Electrical Installation
<11> The sink/source setting for the Safe Disable input is the same as with the sequence input. Jumper S3 has the drive set for an external power
supply. When not using the Safe Disable input feature, remove the jumper shorting the input and connect an external power supply. Refer to
Figure 42 for instructions.
<12> Disconnect the wire jumper between H1 - HC and H2 - HC when utilizing the Safe Disable input.
<13> Monitor outputs work with devices such as analog frequency meters, ammeters, voltmeters, and wattmeters. They are not intended for use as
a feedback-type of signal.
<14> Note that if the drive is set to trigger a fault output whenever the fault restart function is activated (L5-02 = 1), then a sequence to interrupt
power when a fault occurs will result in shutting off the power to the drive as the drive attempts to restart itself. The default setting for L5-02
is 0 (fault output not active during restart attempt).
WARNING! Sudden Movement Hazard. Do not close the wiring for the control circuit unless the multifunction input terminal
parameters are properly set. Improper sequencing of run/stop circuitry could result in death or serious injury from moving equipment.
WARNING! Sudden Movement Hazard. Ensure start/stop and safety circuits are wired properly and in the correct state before
energizing the drive. Failure to comply could result in death or serious injury from moving equipment. When programmed for 3-Wire
control, a momentary closure on terminal S1 may cause the drive to start.
WARNING! When 3-Wire sequence is used, set the drive to 3-Wire sequence before wiring the control terminals and ensure
parameter b1-17 is set to 0 (drive does not accept a run command at power up (default). If the drive is wired for 3-Wire sequence but
set up for 2-Wire sequence (default) and if parameter b1-17 is set to 1 (drive accepts a Run command at power up), the motor will
rotate in reverse direction at power up of the drive and may cause injury.
WARNING! When the application preset function is executed (or A1-06 is set to any value other than 0) the drive I/O terminal functions
change. This may cause unexpected operation and potential damage to equipment or injury.
WARNING! When using the automatic fault restart function while the wiring is made to shut off the power supply when a drive fault
occurs, make sure the drive is set not to trigger a fault output during fault restart (L5-02=0, default). Otherwise the fault restart function
can not work properly.

◆ Main Circuit Connection Diagram

Refer to diagrams in this section when wiring the drive's main circuit. Connections may vary based on drive capacity.
The DC power supply for the main circuit also provides power to the control circuit.
NOTICE: Do not use the negative DC bus terminal "-" as a ground terminal. This terminal is at high DC voltage potential. Improper
wiring connections could damage the drive.
