3.1 Standard Connection Diagram
* 1. Remove the jumper when installing an optional DC reactor.
* 2. The MC on the input side of the main circuit should open when the thermal relay is triggered.
* 3. Self-cooled motors do not require separate cooling fan motor wiring.
* 4. Connected using sequence input signal (S1 to S7) from NPN transistor; Default: sink mode ( 0 V com)
* 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 intended for use as a feedback-type of signal.
* 7. Disconnect the wire jumper between HC and H1 when utilizing the safety input.
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 funcion is executed (or A1-06 is set to any value other than 0) the
drive I/O terminal funcitons change. This may cause unexpected operation and potential damage to
equipment or injury.
Figure 3.2 illustrates an example of a 3-wire sequence.
