2.3 Controls
Fig. 2: Controls
2.3.1 Control keys
Manual setup operation is only available if there is no process data
exchange going on.
Manual setup mode (corresponding to inching mode 2) can be started by means of the control
keys. This enables actuator movement without a superordinate control.
Key : Inching mode 2 in e direction
Key : Inching mode 2 in i direction

2.3.2 DIP switch
DIP-switch is only read in when supply voltage of PLC is switched on. Any
modification will hence only become effective after a power-on reset of the
PLC’s supply voltage.
If station name setting was made via DIP-switch, a subsequent change in
DIP-switch setting to position DCP will lead to a reset of all network
parameter (eg. station name and IP-address) to parameter setting as made
ex factory.

3Digital inputs and outputs
The actuator has four configurable digital inputs and one configurable digital output.
Function and switching behavior can be set.
No function has been assigned to the digital inputs in the factory setting.
The logical status of the digital inputs is mapped in the process data independent of the
assigned function.
If a function was assigned to the digital input, the functions' conditions of the digital inputs
can be read in the register Digital Input Functionalities State (PNU 0405h).
With factory settings, the digital output can be actuated via the process data.
If a function is assigned to the digital output, it is actuated via register
Digital Output Functionalities State (PNU 0302h).

4.1 Control of the drive
The drive can be moved manually via the keys or digital inputs without upstream control. The
drive can be controlled and configured in the bus operating mode and via the service
interface.
4.1.1 Operating modes
The following operating modes are distinguished: positioning mode and speed mode. In the
positioning mode there is the additional option of traveling in the inching mode. The position
control mode can be started via the digital inputs independent of the chosen operating mode.
4.1.1.1 Positioning mode
In the positioning mode, positioning to the specified set point is executed by means of a
ramp function (see Fig. 5: Ramp travel, direct positioning mode) 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 job, the actuator accelerates to the specified speed with the
acceleration programmed. The measure of delay to the setpoint is defined by the parameter
A-Pos (PNU 0604h) as well.
Alternately, a value deviating from acceleration can be chosen for delay by means of
parameter D-Pos (PNU 0606h).
Changing controller parameters during a positioning process does not influence the current
positioning operation.

The status word indicates whether the actual position is within the window defined by
parameter Pos Window (PNU 060Ah). Upon reaching the programmed window via parameter
Inpos Mode (PNU 0616h), you can define the behavior of the actuator.
Fig. 6: Positioning mode
The max. travel range depends on transmission and scaling. The number of revolutions
specified in the product data sheet must not be exceeded.
4.1.1.1.1 Loop positioning
A travel order will not be executed if loop positioning would exceed the
limiting values specified by parameters Software Limit 1 (PNU 060Fh) and
Software Limit 2 (PNU 0610h) although the setpoint is within the limiting
values.
If the actuator is operated on a spindle or an additional transmission, the spindle or external
transmission backlash can be compensated by means of loop positioning. In this case,
traveling to the target value is always from the same direction. This travel direction can be
determined via parameter Pos Type (PNU 0613h). Loop length is set via parameter Loop
Length(PNU 0617h).
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 required 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.

4.1.1.2 Inching mode
There is no compensation for spindle backlash (loop positioning) in this
operating mode.
Inching mode is enabled in the positioning mode only. You can program via parameters
acceleration as well as speed in the inching mode.
4.1.1.2.1 Inching mode 1
If the Spindle pitch parameter is programmed to zero, then the traveling
distance 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.
If the actual position is outside the programmed limiting values, then
traveling from this position in the respective direction must be performed
by means of inching mode 1 or 2!
The drive travels once from the current actual position by the value Delta Inch (PNU 0611h)
depending on the mathematical sign of the value entered.
Delta Inch < 0: negative travel direction
Delta Inch > 0: positive travel direction
Reaching of the target position will be signaled accordingly.
The digital input can be configured for starting inching mode 1.
The following conditions must be met for enabling the start of inching modes 1 and 2:
Supply voltage of the output stage is applied.

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 (PNU 0609h) = 10 rpm (can only be changed in the idle state)
Inching 2 Offset (PNU 061Ah) = 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
Results are always rounded to integers.
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. 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.

4.1.1.4 Position Control Mode
Via the control word in the process data, the superordinate control can
cancel travel jobs started by the position control mode.
For this purpose, a negative flank must be created on bits OFF1, OFF2, or
OFF3 in the control word.
Conversely, the PCM mode cannot cancel a travel order initiated via the
superordinate control.
The position control mode enables travel data sets to be called via the digital inputs. A total
of 7 travel data sets can be saved.
The use of the position control mode requires previous configuration of the digital inputs.
The desired travel data set can be selected via PCM inputs 1 to 3 in binary addressing. Travel
data set 0 does not exist.
