Defines acceleration time 1 as the time required for the
speed to change from zero to the speed defined by

parameter
(not to parameter
).
If the speed reference increases faster than the set
acceleration rate, the motor speed will follow the
acceleration rate.
If the speed reference increases slower than the set
acceleration rate, the motor speed will follow the
reference.
If the acceleration time is set too short, the drive will
automatically prolong the acceleration in order not to
exceed the drive torque limits.
