Posi- and synchronous operating
●
Implementation of the stops:
If the drive has reached position 1 (PS.24 of block 1) or position 2 (PS.24 of block 2), it shall remain
there 500ms or 1200ms and then automatically carry out the next positioning step. To implement this
sequence, the timer functionality must be utilised. With reaching of the target of Index 0 or Index 1,
Timer 1 must be started. The drive then remains at the target position until the timer has exceeded the
time level of 500ms and 1200ms, respectively. Exceeding the time level triggers a "start positioning".
With the start of the next positioning, the timer must be stopped and reset.
The start of the timer must be triggered by a software input. Input IA was chosen here.
→ LE17: timer 1 start inp. sel. = 256: IA
IA is always then set if software output OA is set.
On reaching of the target of Index 1 or Index 2, Timer 1 must be started (i.e., the software output OA must be
set).
Output OA must also be set if the switching condition act.. index = 1 or act.. index = 2 and, simultaneously, the
condition "target reached" are met
→ do.00: Condition 0 = 54: target window reached (positioning)
→ do.16: Condition selection for flag 0 = 1: SB0
→ do.01: Condition 1 = 72: act. position index = level
→ LE.01: Comparison level 1 = 1,00
→ do.02: Condition 2 = 72: act. position index = level
→ LE.02: Comparison level 2 = 2,00
→ do.19: Condition selection for flag 3 = 6: SB1+SB2
→ do.37: Flag selection for OA = 9: M0+M3
→ do.41: AND conn. for outputs = 16: OA
When the timer has counted 1500ms (for index 1) or 1200ms (for index 2), a "start positioning" signal shall
be generated.
As input for the "start positioning" signal, software input IB is used.
→ PS.29 = 576: I3 (X2A.12) + IB
Output OB must therefore be set, when the switching conditions index = 1 (SB1) and timer 1 > 500ms, or
index = 2 (SB2) and timer 1 > 1200ms, are met.
→ do.03: Condition 3 = 37: Timer 1 > level
→ LE.03: Comparison level 1 = 0,50
→ do.04: Condition 4 = 37: Timer 1 > level
→ LE.02: Comparison level 2 = 1,20
→ do.17: Condition selection for flag 1 = 10: SB1+ SB3
→ do.18: Condition selection for flag 2 = 20: SB2+ SB4
→ do.24: SB AND/OR conjunction = 6: M1+M2
→ do38: Flag selection for OB = 6: M1+M2
The resetting of the timer must be triggered by a software input. Input IC was chosen here.
→ LE.19: timer 1 start inp. sel. = 1024: IC
