10.16. Process data
This chapter describes additional functions that provide process data for a higher-level
Controller.
10.16.1. Position counter
This function counts the number of motor revolutions. The current counter content
(actual position) can be output as process date via network to implement a simple
position control in a higher-level Controller.
Preconditions
• The number of motor revolutions is reconstructed from the motor model. For this
purpose, the motor control type "Sensorless control (SL PSM) [3]" must be selected
and set in 0x2C00 (P300.00). Sensorless control for synchronous motors (SL-PSM)

118
• The position control must be implemented in the Controller.
Details
The signal source for the position counter is selected in 0x2C49:001 (P711.01). The
position counter can count forwards and backwards. The current counter content (actual
position) is displayed in 0x2C49:003 (P711.03). After the maximum or minimum value has
been reached, an overflow takes place.
Reset position counter:
• The position counter is reset when the supply voltage is switched on.
• The position counter can be set manually via the "Position counter reset" 0x2631:054
(P400.54) function or the NetWordIN1 0x4008:001 (P590.01) data word. For a reset via
NetWordIN1, the "Position counter reset [54]" function must be assigned to a bit of the
data word. Depending on the selection in 0x2C49:002 (P711.02), the reset can be made
either edge-controlled or status-controlled.

Assignment of a trigger for the "Position counter reset" function.
Trigger = FALSE-TRUE edge: Reset position counter manually.
Trigger = FALSE: no action.
Notes:
In 0x2C49:002 (P711.02)
it can be selected whether the reset is to be
effected edge-controlled (default setting) or status-controlled.

Internal motor model
The motor revolutions reconstructed from the internal motor model of
the sensorless control (SL PSM) are counted.
The counter content will not be updated if the power section is
switched off.
After restarting the power section, the counting of the last counter
content is continued.

Mappable parameter for providing the current counter content (actual
position) via network.
Scaling (applies to every measuring method or encoder resolution):
Upper 16 bits: Counted revolutions (0 ... 65535, overflow possible)
Lower 16 bits: Current position within the revolution (0 ... 65535)
