6.19.3 Functions under torque mode
Velocity limit is required under torque mode to make sure motor rotational velocity stays
within the limit.
Velocity limit function
During torque control, velocity control should be within the range of velocity limit. When
motor reaches velocity limit, command control will switch from torque control to command
control with velocity limit.
Due to gravitational or other external factors, torque command from controller might differ
from the direction of rotation of the motor, velocity limit will be invalid. Please error occurs
in such situation, please set Pr5.13 as stopping velocity. If velocity is over the value set in
Pr5.13, Er1A0 might occur and motor will stop.

If motor speed exceeds Pr5.13, Er1A0 might occur.
When Pr5.13 = 0, overspeed level = max. motor speed x 1.2
