Turntable, two positions and two speeds (p3393 = 6)

Overview
With p3393 (conveyor technology application) set to 6, the converter enables a turntable in a
conveyor system to rotate in either positive or negative direction with variable speeds and
stop at two dedicated positions.
Four 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 either
– The motor stops with OFF1 ramp when either of the two stop sensors (p3384 and
– With the sensor evaluation type (p3394) set to 1 or 2 (level triggering), the motor
