3.2 Standard Connection Diagram
<7> Disconnect the wire jumper between HC and H1 when utilizing the safety input.
66 for details on removing the jumper. The wire length for the Safe Disable input should not exceed 30 m. Use only
dry contacts on safety inputs HC-H1. External power supplies are not permitted.
<8> 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 active during restart attempt).
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.
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.
Figure 3.2 illustrates an example of a 3-Wire sequence.
