Connecting SIMOVERT MASTERDRIVES MC to the Technology-CPU
46 Product Information, 03/2008, A5E00272072-05
SIMOVERT MASTERDRIVES Motion Control
Parameter: P770 (time slice interpolator)
Meaning:
The transition from the position controller clock cycle (Technology CPU) to the sampling time
of the position controller (motion control) is fed through an interpolator that aligns the ratio.
● Up to MASTERDRIVES software Version V2.2
The ratio can only be specified in the form position controller clock cycle/DP cycle=2
(P770-
1)
.
This means that if, for example, the DP cycle and the position controller clock cycle are
the same, you must enter a value of 1 into P770. If the position controller clock cycle is
double the DP cycle, you must set the value to 2.
● From MASTERDRIVES software Version V2.2
The ratio can only be specified in the form
position controller clock cycle/DP cycle=2
(P770-3)
.
If the DP cycle and the position controller clock cycle are the same, then you must enter
the value 3 in P770. If the position controller clock cycle is double the DP cycle, you must
set the value to 4.
Task monitoring time
The task monitoring time monitors the processing of the Motion Control jobs.
Technology DB update
The setting for the time of the technology DB update determines the time intervals in which
the technology DBs in the S7 will be updated.
Maximum task processing
Time monitoring (watchdog) for processing tasks when the CPU transitions from RUN to
STOP.
Number of the tolerated IPO and IPO2 overflows
An "IPO overflow" will occur if the processing of the interpolator (IPO or IPO2) lasts longer
than the configured interpolator clock cycle. In this case the following interpolator cannot be
started in the selected cycle and will be omitted. If the processing of the interpolator is
completed at the next cycle, it will be started as usual.
Each omitted interpolator will be counted as "IPO overflow". Set in the selection list how
many successive "IPO overflows" are tolerated before the technology CPU switches to the
STOP operation mode.
