(b) Torque limit
By setting parameter No.28 (internal torque limit 1), torque is always limited to the maximum value
during operation. A relationship between limit value and servo motor torque is as in (1)(c) of this section.
Note that the analog torque limit (TLA) is unavailable.
(c) Speed limit
1) Speed limit value and speed
The speed is limited to the values set in parameters No.8 to 10, 72 to 75 (internal speed limits 1 to 7)
or the value set in the applied voltage of the analog speed limit (VLA).
A relationship between the analog speed limit (VLA) applied voltage and the servo motor speed is
shown below.
When the servo motor speed reaches the speed limit value, torque control may become unstable.
Make the set value more than 100r/min greater than the desired speed limit value.
The following table indicates the limit direction according to forward rotation selection (RS1) and
reverse rotation selection (RS2) combination.
