Parameter setting & configuration
Control of the program flow via predefined ports
5.11 Control of the program flow via predefined ports
For a sequence control by a higher-level control (e.g. PLC) the application is provided with
predefined ports the signals of which are linked with the setpoint and control inputs of the
application via multiplexer parameters.
Input port "LPortAxisIn1" for control and setpoint signals
Input port "LPortControl1" for control signals
The input port LPortControl1 is intended for the connection with a master control.
Element variable/data type Information/possible settings
nIn1
INT
Profile number (1 .... 75) of the profile of the profile data management to be
executed

WORD
Control word (bit coded)
• Bits which are not listed are not assigned with a function.
Bit 3 Activate quick stop
• The is decelerated to standstill within the deceleration time set
for the quick stop function independent of the setpoint selection.
• If the quick stop function is deactivated, the drive is led to the
selected setpoint again via the set acceleration time.
Bit 7 Reset error
• An existing error status is reset if the cause of the fault is
removed.
Bit 11 Requesting control via the basic function "Positioning"
• If no other basic function is active, the status changes to
"Positioning" and positioning can be executed via the control
inputs.
• If bit 11 is reset, an active positioning is stopped, i.e. it is changed
from the active function state "Positioning" to the basic function
" Standstill" via the function state "Stopping".
Bit 12 Start positioning/restart
• The profile with the profile number defined via nIn2 is executed.
• During an active positioning process, another profile can be
defined via nIn2 which is executed after restart (renewed state
change of bit 12 from "0" to "1").
Bit 13 Profile restart
• Profile data is read in again considering the distances already
covered.
• The positioning process interrupted before is completed.
Bit 14 Profile reset
• Profile data is read in again without considering the distances
already covered.
• The positioning process interrupted before is completed.
Bit 15 Request control via the basic function "Homing" and start reference
search in the selected homing mode (C02640).
