3.4.6  Optimizing the speed controller in the drive 
Introduction 
The controllers in the drive must be working optimally to ensure that systems are not 
susceptible to faults. 
There are tools for automatically optimizing the controller in  
SINAMICS firmware version V2.5 and S7 Technology V4.1 or later. 
The following requirements must be fulfilled to use automatic controller optimization: 
●  The drive may be moved without hitting the mechanical limits 
●  The drive is running in "SERVO" mode. 
●  The motor encoder performs the closed-loop control. 
●  There is an online connection to the relevant drive unit. 
●  The open-loop control is in STOP mode.
