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

nIn1

INT

Profile number (1 .... 75) of the profile of the profile data management to be

executed

Element variable/data type

Information/possible settings

LPortControl1

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).
