Basic positioner (EPOS) Positions axes in absolute/relative terms with a motor en-
EPOS
Speed control (S) Flexibly controls motor speed and direction through
PROFINET communication port
S
Safe Torque Off (STO) Safely disconnects torque-generating motor power supply
to prevent an unintentional motor restart
EPOS, S
One-button auto tuning Estimates the machine characteristic and sets the closed
loop control parameters (speed loop gain, speed integral
compensation, filter if necessary, etc.) without any user
EPOS, S
Real-time auto tuning Estimates the machine characteristic and sets the closed
loop control parameters (speed loop gain, speed integral
compensation, filter if necessary, etc.) continuously in real
time without any user intervention
EPOS, S
Resonance suppression Suppresses the mechanical resonance, such as workpiece
EPOS, S
Low frequency vibration suppres-
Suppresses the low frequency vibration in the machine
EPOS
Speed limit Limits motor speed through internal speed limit commands
EPOS, S
Torque limit Limits motor torque through internal torque limit commands
Basic operator panel (BOP)
Displays servo status on a 6-digit 7-segment LED display
External braking resistor - DCP, R1 An external braking resistor can be used when the internal
braking resistor is insufficient for regenerative energy
EPOS, S
Digital inputs/outputs (DIs/Dos) Control signals and status signals can be assigned to four
programmable digital inputs and two digital outputs
EPOS, S
PROFINET communication Supports communication between the SINAMICS V90 PN
servo drive and PLC with PROFINET communication proto-
col
EPOS, S
SINAMICS V-ASSISTANT You can perform parameter settings, test operation, ad-
justment and other operations with a PC
