Turntable, Three Positions And One Speed (P3393 = 7) - Siemens SINAMICS G115D Operating Instructions Manual

6.9.2.3

Turntable, three positions and one speed (p3393 = 7)

Overview
With p3393 (conveyor technology application) set to 7, the converter enables a turntable in a
conveyor system to rotate in either positive or negative direction with a fixed speed and stop
at three dedicated positions. Three sensors are required to signal the limit positions for the
motor to stop.
Precondition
• You interconnect the signals of the sensors with the digital inputs of your choice.
• Depending on the specific application and mechanical setup, you must set end position
shutdown active (p3392) to 1, so as to limit the turntable movement between the
dedicated positions.
Function description
• With the ON command, the motor accelerates to its speed setpoint (p1070). The turntable
can rotate in either positive or negative direction depending on the setting of p1113:
– p1113 = 0: positive direction
– p1113 = 1: negative direction
• With the end position shutdown deactivated (p3392 = 0), the following applies:
– The motor stops with OFF1 ramp when any of the three stop sensors (p3384, p3385,
– With the sensor evaluation type (p3394) set to 1 or 2 (level triggering), the motor
– Setting the sensor bypass signal (p3390) to 1 overrides the sensor signals p3384,
