22.02 Acc time1 Defines acceleration time 1 as the time required for the speed
to change from zero to the speed value defined by parameter
19.01 Speed scaling.
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
signal.
If the acceleration time is set too short, the drive will
automatically prolong the acceleration in order not to exceed
the drive torque limits.
