Functional Description Positioning Module
6.11.19 Programming
Examples
Positioning control
with four positions
Requirements:
• four different positions shall be approached by the control
• the addressing of the positions is done by way of erminal strip
• the positioning starts with ‘start positioning’ - signal
• output D1 shall be set when the target is reached
• after power-on the reference point approach shall be started with ‘start
positioning’
• the positions are adjusted absolute referring to the reference point
(adjustment in increments, position setpoint values = 80500, 1286000,
24000, 163800)
• the absolute positions - 320000 and +1500000 are the limit for the
position setpoint value
• the positions are indicated and adjusted in decimal values
• when a digital input is set it shall be possible to handle the drive manually
with the analog setpoint value (emergency operation)
• the left limit switch is also the reference switch with turning back to zero
position
Sequence:
• the control selects the positioning set
• after that the control gives ‘start positioning’
(positioning set must still be present at the terminal strip)
• the controller takes the position, speed and controller setting etc. from the
selected positioning set
• after reaching the target window and termination of precontrol signal the
‘target window reached‘ signal is set
• only now new set addresses and a new ‘start positioning’ -command
are accepted
• the signal ‘target window reached’ is reset with the new ‘start
positioning’ -command
• if I4 is activated the controller operates with the analog setpoint value
Positioning - control (Pc) - Parameter
Pc. 0 Positioning module 1 on
Pc. 1 Adjustment mode 0 position display / -setting in increments
Pc. 4 Limit position left sign -1 negative position value for limit position left
Pc. 5 Limit position left high 32 limit position left high * 10000 = 320.000 increments
Pc. 6 Limit position left low 0 limit position left low = 0 increments
Pc. 7 Limit position right sign 0 positive position value for limit position right
Pc. 8 Limit position right high 150 limit position right high * 10000 = 1.500.000 increments
Pc. 9 Limit position right low 0 limit position right low = 0 increments
Pc.10 Reference point mode 1 auto ref on
Pc.11 Reference point sign 0
Pc.12 Reference point high 0 reference point position = zero point
Pc.13 Reference point low 0
Pc.14 Reference speed -100 the reference point is searched for with a speed of 100 rpm in rotation
direction left / automatic reversal of rotation direction on reaching the limit
switch / negative speed, since the reference point lies on the left limit
