Meaning
The following errors trigger a
diagnostic message:
Short circuit of digital output
•
Short circuit of the encoder
•
supply
Parameter assignment error
•
The 2PULSE detects the short
circuit error on the digital output
DO 0.
All the preset times are
specified at a resolution of 1 ms.
The pusher is controlled
immediately with the software
enable.
This is 500 ms in the selected
time base
This is 1 s in the selected time
base. This results in an
interpulse period of 500 ms.
