P3-33
Internal torque
command
0 1% rated torque -1000~+1000 Anytime At once
The unit of this parameter is 1% of the rated torque.
For example: P3-33=50, motor forward run with 50% of the rated torque;
P3-33= -20, motor reverse run with 20% of the rated torque.
In addition to using the torque to control the direction of servo operation, it can also use / SPD-D to control
the direction.

Note: Even if the setting speed of this parameter is greater than the speed limit of P3-14, the actual
effective speed limit is the lower speed limit. (The maximum speed is the smaller value in P3-14/P3-15
and P3-16/P3-17)
4.5.1.3 Speed reach signal output (/VLT)
In torque mode, when the absolute value of the actual speed of the servo motor exceeds the speed limit value,
it is considered that the actual speed of the servo motor is limited. At this time, the servo driver can output
/VLT signal. Otherwise, if any condition is not met, the speed limit signal is invalid.
