Start/Stop setup (M3.2)
The start/stop commands are given from different locations depending on the selected control place.
Auto Control Place I/O A: Start, stop, and reverse commands are controlled by two digital inputs chosen with
Control Signal 1 A (P3.5.1.1) and Control Signal 2 A (P3.5.1.2). The functionality/logic for these inputs is
selected with I/O A Start/Stop Logic (P3.2.6). The I/O B Control Force (P3.5.1.5) will determine when the
Auto Control Place I/O B is in use.
Auto Control Place I/O B: Start, stop, and reverse commands are controlled by two digital inputs chosen with
Control Signal 1 B (P3.5.1.3) and Control Signal 2 B (P3.5.1.4). The functionality/logic for these inputs is
selected with I/O B Start/Stop Logic (P3.2.7). The I/O B Control Force (P3.5.1.5) will determine when the
Auto Control Place I/O B is in use.
Keypad (Hand) Control Place: Start and stop commands come from the keypad buttons, while the direction of
the rotation is selected by Keypad Direction (P3.3.7). The speed of the motor is controlled from the keypad
buttons or by setting Keypad Reference (P3.3.6). The Keypad Control Reference Selection (P3.3.5) must be
set to a value of Keypad Reference for this work as stated.
Fieldbus Control Place: Start, stop, and reverse commands come from the fieldbus. The functionality/logic for
the start/stop is selected with Fieldbus Start Logic (P3.2.8). The speed of the motor is controlled as selected
with Fieldbus Control Reference Selection (P3.3.9).

Start/Stop commands are given
differently depending upon the
control place. This parameter
defines whether the Start/Stop
command is controlled by digital
inputs as defined in Control
Signal 1 A (P3.5.1.1) and Control
Signal 2 A (P3.5.1.2) in
accordance with the I/O A
Start/Stop Logic (P3.2.6) or if the
Start/Stop command is controlled
by the fieldbus that is in use.
Settings:
0 = I/O Control (control is from
the physical I/O, PID control, or
time channels)
1 = Fieldbus (control is from the
configured fieldbus found in
Ethernet or RS-485 settings)
