Source of torque limit
● SINAMICS V90 PN
Two sources in total are available for torque limit. You can select one of them via the
digital input signal TLIM:
When the torque setpoint reaches torque limit, the torque is limited to the value selected
by TLIM.
Note
You can switch between the two sources and modify their values when the servo drive is
running.
For more information about the digital input signal TLIM, see Section "DIs (Page 94)".
● SINAMICS V90 PTI
Four sources in total are available for torque limit. You can select one of them via a
combination of digital input signals TLIM1 and TLIM2:
When the torque setpoint reaches the torque limit, the torque is limited to the value
selected by TLIM1/TLIM2.
Note
These four sources are valid in control modes PTI, IPos, and S. You can switch among
them when the servo drive is running.
