4.1.1.2.2 Inching mode 2
The actuator travels from the current position as long as the relevant command is active. You
can influence the inching speed via two parameters and it will be calculated in the actuator
as illustrated in the example below:
V-Inch (Object 2609h) = 10 rpm (can only be changed in the idle state)
Inching 2 Offset (Object 261Ah) = 85 % (can be changed during inching operation)
The resulting inching speed in this example will be:
Inching speed= v - Tipp * Offset inching 2 = 10 rpm * 85 % = 9 rpm
The results are always rounded to integers.
The minimum speed is 1 rpm.
4.1.1.3 Rotational speed mode
Limits 1 + 2 are inactivated in this operational mode
Exceeding the resolution of the absolute encoder results in a jump of the
actual position.
With the set point enabled, the actuator when in the rotational speed mode accelerates to the
target speed and maintains this speed until the set point is disabled or a different target
speed specified. The speed is adjusted immediately to the new value when the rotational
target speed is changed.
The arithmetical sign of the set point determines the travel direction in the rotational speed
mode.

The following conditions must be met for enabling the start of the rotational speed mode:
Supply voltage of the output stage is applied.
