Explanation
Stops with dynamic brake (for a servo amplifier without the dynamic brake, the servo motor coasts).
The time constant τ for the electronic dynamic brake will be shorter than that of the normal dynamic brake. Therefore,
the coasting distance will be shorter than that of a normal dynamic brake.
Performs forced stop deceleration.
Stops with dynamic brake by activating the STO function. For the operation sequence of this stop method, refer to the
following.
