General commissioning information

6.1.1

Introduction

The safety functions are commissioned using the screen forms in the STARTER. These
functions are available for each drive at "Functions" -> "Safety Integrated".
The password "0" is set by default.
Information pertaining to operation with isochronous PROFIBUS
NOTICE
Always set parameter p9510 = 1 if a PROFIdrive controller exchanges isochronous process
data with the Control Unit. This setting is also required if the drive itself does not exchange
process data in isochronous mode. Refer to parameter p0092.
6.1.2

Setting the sampling times

Terminology
The software functions installed in the system are executed cyclically at different sampling
times (p0115, p0799 and p4099).
Safety functions are executed within the monitoring clock cycle (p9300/p9500) and TM54F is
executed within the sampling time (p10000).
Communication on PROFIBUS is handled cyclically by means of the communication clock
cycle.
Rules for setting the sampling times:
● The monitoring clock cycle (p9300/p9500) on isochronous PROFIBUS must be an integer
● The monitoring clock cycle must be an integer multiple of 1 ms if isochronous PROFIBUS
