If a traversing block with the number x+1 should be started after
a specified time following traversing block x, this specified time
must be configured in traversing block x.
The following conditions must be observed for implementation:
S
Traversing block x
– Timer mode: "Traverse as long as the timer is running"
(P80:x.2 = 0)
– Timer value: desired delay in ms (P84:x)
– PSW (program control word): "Defined delay before next
traversing block" (P80:x.13 = 1)
S
Traversing block x+1:
– PSW (program control word): "Wait for start condition"
(P80:(x+1).7 = 0)
This special delay is handled internally in the drive. It can not be
checked via parameter P45 (timer status).
In this case, traversing block x+1 starts regardless of the length
of the traversing path in traversing block x.
If traversing block x is interrupted early due to the loss of a start
condition (SMStart), traversing block X+1 also will not start until
the time has expired (case 4).

Case 1: Normal process
Block 1
nt (P80:13 = 1)
Case 2: Traversing block longer than timer value
v
(abortion)
Block 1
nt (P80:13 = 1)
Case 3: Terminal function (SimoCom A)
v
Start bit = 1
Block 1
nt (P80:13 = 1)
Case 4: Terminal function (SimoCom A)
Start bit = 1 Start bit = 0
v
Block 1
nt (P80:13 = 1)
nt is the timer value of block 1
