Task description
Jog 1 and 2 are to be set up via the input terminals of the CUD. A parameter request is to be
used to write the corresponding parameters as follows:
•
BI: p1055 = r53010.0
Jog bit 0
•
BI: p1056 = r53010.6
Jog bit 1
•
p50436[0] = 5%
Jog 1 speed setpoint
•
p50436[1] = 10%
Jog 2 speed setpoint
The request is to be handled using a request and response data block.
