Example 4: Positioning of a workpiece for various processing steps / sequence control by timer-func-
tionality and the input / output handling of the inverter
Sequential positioning with stop between the positioning steps and denition of the prole speed by PS.25.
Note: this example requires detailed knowledge of the timer functionality and of the input / output handling.
These chapters must therefore be read prior to programming an internal sequence control system. If no internal
control is to be implemented, this example can be skipped.
Settings:
● The position at which the workpiece starts has the value 0.
● Driving to this position (whether after "power on“, after error or as part of the positioning process) can
always occur at maximum speed = 1500 rpm.
● The rst stop shall be at position 100,000. The prole speed up to that point shall be 1000 rpm. The
stop shall last 500 ms, and the drive shall continue automatically after that time. The drive shall signal
the control through an output that it has reached the target with an accuracy of 10 increments, so that
the processing can begin.
● The second stop shall be at position 200,000. The prole speed up to that position shall again be 1000
rpm. The stop shall last 1200 ms and the drive shall return to the starting position automatically after
that time. The drive shall signal the control through an output that it has reached target 2 with an accu-
racy of 10 increments, so that the processing can begin.
Adjustments:

The maximum prole speed is set via PS.25 "Index / speed".
All other bits can remain at the factory settings for this example and are explained in the following chapters.
● Block 0 denes the start position → PS.28 = 0
● Input I3 serves as "start positioning" → PS.29 = 64: I3 (X2A.12)
● Target window size shall be 20 increments (= 2 x accuracy) → PS.30 = 20
Reaching of the target window shall be indicated by output O1:
→ do.00: Condition 0 = 54: target window reached (positioning)
→ do.16: Condition selection for ag 0 = 1: SB0
→ do.33: Flag selection O1 = 1: M0
