Selection of the operating mode for the channel
You use this parameter in "Manual operation" to specify the main task for which the channel
of the technology module is used. This defines the setting options under "Parameters"
(hardware configuration).
Operating mode
Description
Counting (Page 22) / Position
input (Page 24)
The main function of the channel is counting or position input. The
comparison functions and hardware interrupts work with the counter
value or position value. The measured values are available concur-
rently.
Measuring (Page 54) The main function of the channel is counting. The comparison func-
tions (Page 52) and hardware interrupts for compare events work
with the measured value. The counter value is available concurrent-
ly.
Module parameters (position input for Motion Control)
In operating mode "Position input for "Motion Control" technology object", the parameters for
the encoder signals of the channel are assigned under "Module parameters". The
parameters depend on the encoder used.
Module parameters for incremental encoders and pulse encoders
If you use an incremental or pulse encoder, you need to configure the following parameters
for the encoder signals of the channel.
● Signal type
● Invert direction
● Signal evaluation
● Filter frequency
● Sensor type (for TM Count)
● Interface standard (for TM PosInput)
● Signal selection for reference mark 0
● Steps per revolution and
● Reference speed
You can find a description of the first six parameters in section Counter inputs
(High_Speed_Counter) (Page 99).
