3Display and Control Keys
3.1 General
The actuator has a two-line display with special characters and three control keys. The keys
serve for actuator parameterization and control. Two LEDs (1, 2) inform about the actuator's
operating state.
Fig. 2: Control elements
3.2 LCD display
With supply voltage applied to the control, the actual value is displayed in the first line and
the set point value with factory settings in the second line.
The value displayed in the 2nd line can be adjusted via parameters.

4Functional Description
4.1 Control of the drive
The drive can be controlled manually (stand-alone) and completely parameterized via the
keys. In bus operation you can disable drive control via the keys.
4.1.1 Value input
Enter values via the key and the key. Confirm entered values by pressing the key.
- Decimal place selection key
- Value input key
With value input via the keys, the display range is limited to -19999 …
99999. When entering values beyond this range via SIKONETZ5 or the
service protocol, "" will be displayed when you select the parameter.
4.1.2 Value selection
For some parameters you can select values from a list. Direct value input is not possible.
You can select a value from the list via the key. Confirm the value by pressing the key.
4.1.3 Operating modes
The following operating modes are distinguished: positioning mode and speed mode. In the
positioning mode there is the additional option of travelling in the inching mode.
4.1.3.1 Positioning mode
In the positioning mode, positioning to the specified set point is executed by means of a
ramp function (see Fig. 3), calculated on the basis of the actual position as well as the
programmed controller parameters P (proportional factor), I (integral factor), D (differential
factor), acceleration and speed.
Upon activation of the travel order, the actuator accelerates to the specified speed with the
acceleration programmed. The value of deceleration to the set point is defined by the
parameter 'a-Pos' as well.
If the actual position is within the programmed window, this will be signalled by LED1, in the
system status word and in the SIKONETZ5 status word. You can define the behaviour of the
actuator upon reaching the programmed window.
Changing controller parameters during a positioning process does not influence the current
positioning operation.

Fig. 3: Ramp travel, direct positioning mode
4.1.3.1.1 Loop positioning
If the actuator is operated on a spindle or an additional gear, the spindle or external gear
backlash can be compensated by means of loop positioning. In this case, travelling to the
target value is always from the same direction. This direction of approach can be defined.
Example:
The direction from which every target position shall be driven to is positive.
Case 1 new position is greater than actual position:
Direct travel to the target position
Case 2 new position is smaller than actual position:
The actuator drives beyond the target position by the loop length; afterwards, the set
point is approached in positive direction.

4.1.3.2 Inching operation
Inching operation is enabled in the 'positioning mode' only. You can program via parameters
acceleration as well as speed in the inching mode.
There is no compensation for spindle play (loop positioning) in this
operating mode.
4.1.3.2.1 Inching mode 1
The drive travels once from the current actual position by the position 'Delta Tipp' depending
on the mathematical sign of the value entered.
'Delta Tipp' <0: negative travel direction
'Delta Tipp' >0: positive travel direction
If the 'Spindle pitch' parameter is programmed to zero, then the travelling
way occurs by increments. If 'Spindle pitch' is unequal zero, then the
information of the 'Delta Tipp' parameter refers to the travel distance in
1/100 mm.
Reaching of the target position will be signalled accordingly.
The following conditions must be met for enabling the start of inching modes 1 and 2:
The actuator must not be switched to error
No active travel job
Supply voltage of the output stage is applied
If the actual position is outside the programmed limiting values, then
travelling from this position in the respective direction is possible by means
of inching mode 1 or 2!
4.1.3.2.2 Inching mode2
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 - Tipp (Parameter no. 9) = 10 rpm (can only be changed in the idle state)
Offset inching 2 (Parameter no. 30) = 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.

4.1.3.3 Rotational speed mode
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.
Fig. 5: Ramp rotational speed mode
The following conditions must be met for enabling the start of the rotational speed mode:
The actuator must not be switched to error
No active travel job
Supply voltage of the output stage is applied
Limits 1 + 2 are inactivated in this operational mode.
4.1.4 Current limiting
The actuator is equipped with adjustable current limiting, which serves primarily for
protecting the actuator against overload.
With the default value set, the nominal speed indicated on the data sheet is achieved.
Actuator overload results in limiting the motor current to the set value.
As a consequence, the actuator cannot maintain the speed set, the contouring error increases.
With the contouring error exceeding the contouring error limit the actuator will enter the
state of error: contouring error.
The actual motor current cannot be stated by measuring the supply current.
With cycled output stages, the supply current does not correspond to the
motor current. The actual motor current can be read out via the interface or
indicated on the display.
