Two sources in total are available for torque limit. You can select one of them via the
digital input signal TLIM:
Digital input (TLIM)
Torque limit
0
Internal torque limit 1
1 Internal torque limit 2
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 th
eir 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:
Digital signal

Internal torque limit 3
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.
