Motor/Amplifier Speed and Load
Relationship
The motors maximum speed is
dependent on the bus voltage and
motor KE by the following relationships.
In the Velocity Mode of operation, the
TAC Gradient also would limit the
speed.
(AC Input)/(Motor KE vrms) = Max no load speed.
Max no load speed
*
.75 = Maximum speed at continuous full
load.
10/TAC Gradient = (MAX no load speed)Krpm
