Torque limit of speed control mode
When using the speed mode, the main parameters related to the torque limit are PA05 and
PC25. The table below shows these two parameters:

There are 3 input terminals in CN1, including one analog voltage signal input terminal and two
digital input, which are explained in the following table:

TLA
To use this signal in speed control mode, you
should enable TL by PD02~PD09 or PD21~PD24
setting. When TLA is valid, the torque of the servo
motor is limited in the entire system. Please apply a
voltage of DC0~10V to TLA-LG circuit. TLA is
connected to the positive polarity of power and the
maximum torque will be generated at +10V.

option
TL
When this signal is used, you should activate
PD02~PD09 or PD21~PD24 first. The internal torque
limit 1 (PA05) is valid when TL-SG is open, and the
analog torque limit (TLA) is valid when TL-SG is
short-circuite.

option
TL1
When this signal is used, you should activate
PD02~PD09 or PD21~PD24 first. The internal torque
limit 2 (PC25) is valid when TL1-SG is short.
Pt,Pr,S,T
Only when set the PD02~PD09 parameter to enable TL1, internal torque limit 2(PC25) is valid.
There are 4 combinations which are decided by the DI of TL and TL1.
The usage of torque limit value (TL), inner torque limit option (TL1) and analog torque limit
(TLA) are shown in the table below:
