i950 ES: Slip compensation - deactivation in the end range does not work outside the PDSS function (corrected from V01.03.05)
Corrected from:
i950 Extended Safety (ES): from V01.03.05
Response of the new version:
It is now ensured that the slip compensation in the end ranges is deactivated independently of a safety function if this is specified via the safe parameterisation.
What happens?
The deactivation of the slip compensation in the end ranges does not work and the slip is permanently compensated over the complete travel.
When parameterising diagnostic marks, the travel range can be divided into three ranges:
1. Left end area,
2. Medium travel range,
3. Right end area.
If slip between the motor encoder and the load encoder is to be expected due to operation, e.g. with a friction wheel drive, the slip can be cyclically evaluated and compensated for by the slip compensation. The function is intended in particular for the middle driving range. It leads to a reduction of the end ranges and serves to increase the availability of the system.
The slip compensation should be able to be permanently activated independently of a safety function, e.g.: PDSS, can be activated permanently. It can be deactivated for the end ranges through appropriate parameterisation.
When does the behaviour occur?
Application where slip between motor encoder and load encoder is to be expected due to operation, e.g. with a friction wheel drive,
the slip compensation for the end ranges is deactivated via the safe parameterisation and
the PDSS function is not parameterised or not activated.
