Functional DescriptionPositioning Module
Requirement:
• 7 different positions shall be aproached automatically one after the other
in a cyclic manner
• to start each new positioning Start Positioning must be given
• the reference point has the absolute value + 100.000 , the limit switches
are at position 0 and + 200.000
• the reference point approach is started with a digital input
• from the reference point a setpoint position of :
+ 75000 / - 50.000 / - 50.000 / - 50.000 / -15.000 / + 100.000 / - 10.000
shall be driven
• the relay shall process the ‘Target window reached’ - signal
Sequence:
• after ‘power on’ the reference point approach can be started with I2. If the
reference switch I3 is active the actual position is overwritten with the
reference position and the mode is terminated
• now the positoning in set 1 is started with I1
• with each further positive edge of I1 the next position is approached
• in set 0 the drive returns to its reference position
