Turntable, three positions and two speeds (p3393 = 8)

Overview
With p3393 (conveyor technology application) set to 8, the converter enables a turntable in a
conveyor system to rotate in either positive or negative direction with variable speeds and
stop at three dedicated positions.
Six sensors are required to signal the limit positions for the motor to stop or decelerate. In the
mechanical setup of the conveyor system, you must install the stop sensor and low speed
sensor in a line. So do the stop and low speed cams. Besides, when setting up the cams, the
low speed cam must be longer than the stop cam.
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 the high speed setpoint (p3397). 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 decelerates with OFF1 ramp to the low speed setpoint (p3398) when any of
– 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

starts again in either positive or negative direction when the level is canceled; with
p3394 set to 3 or 4 (edge triggering), a new ON command must be initiated to start
the motor again in either positive or negative direction.
