(4) Timing chart upon overheat of external regenerative resistor
Upon overheat of the external regenerative resistor, the motor decelerates at the maximum
performance and, after being stopped, it coasts to stop.
Therefore apply the brake when overheat of the external regenerative resistor is detected.
Build the program so that the brake is released when overheat is removed from the external
regenerative resistor.
The brake is for retention purpose. Because application of the brake during rotation reduces the life,
avoid repetitive application.
