1 - Under normal operation the ramp-down time is defined as the time taken
to ramp-down from the value set in P013 to 0. Setting P040 to 1 will
automatically re-scale the ramp down time so that the motor will always stop
in the same position regardless of operating frequency.

e.g. P003 = 1s, P013 = 50Hz, P012 = 0Hz.
If the motor is running at 50Hz and a stop command applied, the motor will
stop in 1second. If the motor is running at 25Hz, the motor will stop in 2
seconds and if the motor is running at 5Hz, the motor will stop in 10 seconds.
In each case, the motor will stop at the same position.
