7. BASIC OPERATIONS AND TRIAL RUN
F4-11 = 2: Three-wire Control Mode 1. In this mode, DI3 is a three-wire control
terminal. DI1 is set for forward run function and DI2 is set for reverse run function.
The parameters are set as below:
F4-11 = 3: Three-wire Control Mode 2. In this mode, DI3 is three-wire control terminal. DI1
determines whether the RUN command is enabled and DI2 determines running direction.
The parameters are set as below:
In this mode, on normal condition (SW3
closed), after you press down SW1, motor
rotates in forward direction. After you press
down SW2, motor rotates in reverse direction.
Motor stops immediately when SW3 opens.
SW3 must remain closed during START
sequence and during normal RUN operation.
Signals from SW1 and SW2 are valid only with
SW3 closed. The motor status is determined
by the key that you last press.
In this mode, when SW1 is closed,
after you press SW2, motor rotates in
forward direction with K open and in
reverse direction with K closed. Motor
stops immediately when SW1 opens.
SW1 must remain closed during START
sequence and during normal RUN
operation. Signals from SW2 are valid
only with SW1 closed.
