Changing Parameters during Operation

Introduction
You can change several of the 1STEP 5V/204kHz parameters during operation without
having to reassign the parameters of the whole ET 200S station.
This is only necessary if the areas you require for start-stop frequency F
F , and acceleration/delay cannot be covered in the positioning job because of a change to
a
the reduction factor and to the multiplier for the output frequency.
Parameters That Can Be Changed
The parameters
● Base Frequency F
● Multiplier n for start-stop frequency F
● Multiplier i for acceleration/delay
can be changed.
When you start changing parameters by means of the C_PAR control bit, the parameters are
checked for permitted limit values. If you do not adhere to the limit values, the ERR_JOB
feedback bit is set.
Only the feedback bits for the ERR_JOB and STS_JOB job processing are affected when
you change the parameters.
All the other feedback messages are not affected by this job.
