Issued: 02/2008 Frequency Converter SINAMICS G120 on PROFIBUS DP and PROFINET
Preface Notes Startup with PROFIBUS Startup with PROFINET Program Example
• Special Functions for Startup
• Resetting of the parameters to the plant setting
• Quick commissioning
• Calculation of motor/control data
• Motor data identification
Restart Functions
• Setpoint channel can be set
• Ramp generator can be set
• Inching mode
• Free function blocks (FFB)
• Fast free function blocks (fast FFBs)
• Positioning deceleration ramp
• Automatic restart (WEA)
• Flying restart allows for starting the converter while the motor is rotating
• Current limiting
• Slip compensation so the speed of a drive does not change depending on the load
• Motor holding brake (MHB)
Control Functions
• V/f control with different curves
• Vector control without encoder (SLVC) for speed and torque
• Vector control with encoder (VC) for speed and torque
Protection Functions
• Motor protection functions
• Converter protection functions
• Plant/system protection functions
Failsafe Functions (only for CU240S DP-F)
• Safely switched off moment of force (STO)
• Safe stop 1 (SS1)
• Safely limited speed (SLS)
• Safe break control (SBC)
• The failsafe functions can be triggered by means of digital outputs (FDI0A … FDI1B) or
PROFIsafe.
