■ 5: 3-Wire Seq.
Setting Value Function Description
5 3-Wire Seq.
Sets the direction of motor rotation for 3-wire sequence.
If the 3-wire sequence is set to a terminal that is not MFDI terminals DI1 and DI2, these terminals will be the
input terminals for Forward run/Reverse run command. The drive will automatically set terminal DI1 to Run
command (RUN) and terminal DI2 to Stop command (STOP).
When terminal DI1 (Run command) activates for 1 ms minimum, the drive rotates the motor. When terminal DI2
(Stop command) deactivates, the drive stops. When terminal DIx that is set in 3-wire sequence deactivates, the
drive operates in the forward direction, and when it activates, the drive operates in the reverse direction.
WARNING! Sudden Movement Hazard. Set the MFDI parameters before you close control circuit switches. Incorrect Run/Stop
circuit sequence settings can cause serious injury or death from moving equipment.
WARNING! Sudden Movement Hazard. When you use a 3-Wire sequence, set A1-03 = 3330 [Init Parameters = 3-Wire
Initialization] and make sure that b1-17 = 1 [RUN@PowerUp Selection = Disregard RUN] (default). If you do not correctly set
the drive parameters for 3-Wire operation before you energize the drive, the motor can suddenly rotate in reverse when you
energize the drive.

Note:
• To input the Run command, activate the terminal for 1 ms minimum.
• The default setting for b1-17 [RUN@PowerUp Selection] is 1 [Disregard RUN]. If you enable the Run command when the drive is
energized, the protective function activates and the flashes quickly. When the application allows Run, set b1-17 = 2 [Accept
RUN].
■ 6: Jog Reference
Setting Value Function Description
6 Jog Reference
Sets the drive to use the JOG Frequency Reference (JOG command) set in d1-17. The JOG Frequency Reference (JOG
command) overrides Frequency References 1 to 16 (d1-01 to d1-16).
