Start/Stop Setup (M3.2) - Siemens bt300 Operator's Manual

Chapter 4 - Parameters and Menu Structure
Parameters (M3)
Over-voltage controller (P3.1.2.15) and Under-voltage controller (P3.1.2.16)
These parameters allow the under-/overvoltage controllers to be switched out of operation. This may be useful, for
example, if the mains supply voltage varies more than -15% to +10% and the application will not tolerate this over-
/under-voltage. In this case, the regulator controls the output frequency taking the supply fluctuations into account.
Over-voltage and Under-voltage controllers are enabled by default.

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).
