Abstract
PURPOSE: To greatly shorten the time of acceleration of a motor without increasing the capacity of the motor and an inverter, only by applying multistage frequency instruct instructions.
CONSTITUTION: When a current frequency (V/f)1 is constant, a frequency instruction fs1 of such gradient is applied that the motor 2 is accelerated at the maximum rate and a current I1 is equal to an allowable current Ia of the inverter 1. Another frequency instruction fs2 of gradient equal to such a gradient is thereafter applied that a current I0 is equal to an allowable current I2 of the inverter 10 when a stationary rotational frequency is reached. The motor 2 is quickly accelerated under the frequency instruction fs1 because the maximum allowable current Ia flows. Since a spindle is a load of constant torque characteristic, the current I1 is constant when the current frequency (V/f)1 is fixed. Therefore, the inverter 1 is not tripped and a stable run is.
