Acceleration assistance
Acceleration assistance function enables the user to set motor current reference
used during acceleration. This setting makes the drive to extremely develop energy
in the motor that is necessary to accelerate high load at fast ramp rate. The function
works until the motor accelerates to a desired speed and then continues with
energy efficiency settings set by the user in group 80 Voltage control (page 546).
