<5> Use only a +24 V internal power supply in sinking mode; the source mode requires an external power supply
Refer to I/O Connections on page
<6> 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.
<7> Disconnect the wire jumper between HC and H1 when utilizing the safety input.
on page 60 for details on removing the jumper. The wire length for the Safe Disable input should not exceed
30 m.
<8> 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.
WARNING! Sudden Movement Hazard. Do not close the wiring for the control circuit unless the multifunction input terminal parameter
is properly set (S5 for 3-Wire; H1-05 = "0"). 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.
Figure 3.2 illustrates an example of a 3-Wire sequence.
