Machine Data, Modes and Traversing Programs IP 266
Figure 5-11 illustrates a positioning operation in the "Jog 1" mode. "Forward"
starts the positioning operation. "Stop" initiates a defined deceleration
procedure. The "Reverse" function is executed as soon as the drive reaches zero
speed, as it was issued while deceleration was still in progress.
A direct change from Forward to Reverse is permitted.

The drive moves at 100% of the specified speed.
"Stop" initiates a defined deceleration procedure.
You can vary the speed with the Override factor. The IP 266 permits entry of an
Override factor of from 1% to 200% of the specified speed.
Note:
Theoretically, an excessively high Override factor could result in the drive
exceeding the maximum speed. In this case, the IP 266 positions at maximum
speed and flags the discrepancy on the monitor's error line.
