Title: Method of controlling inverter
Inventor: YAMAMOTO IZUMI
IPC: H02P27/06
Filed: 1989-04-05
Abstract: PURPOSE:To prevent a compressor from locking when the operating frequency of the compressor is reduced by controlling a load based on a predetermined V/F pattern when the operating frequency of a load is raised, and controlling the load based on a different V/F pattern when the dropping difference of the operating frequency is large. CONSTITUTION:When the operating frequency of a compressor 1 is raised, PWM data is calculated based on a V/F pattern B stored in a memory 7 by a controller 6, and the compressor 1 is controlled in response to the data. If the frequency of the compressor 1 is reduced from a point (a) to a point (b), when the frequency reaches a point (c), the pattern B is switched to a V/F pattern A. That is, a voltage applied to the compressor 1 becomes higher than that of the pattern B between the point (c) and the point (b). Thus, since a decrease in the motor torque of the compressor 1 is suppressed to a small value, the compressor 1 is not locked even if a pressure difference remains large.

Abstract: PURPOSE:To prolong the service life of a photosensitive drum by constituting the titled recorder so that with respect to a recording operation cancelable state generated in the course of a pre-rotation, it can be received in a real time, and the recorder can be stopped within the operating time of a post- rotation. CONSTITUTION:Whether a pre-processing rotation is being executed or not is discriminated by a pre-processing rotation discriminating means F, and in the course of its pre-processing rotation, a processing command means E decides the sort of an inputted signal. As a result of decision, when a prescribed condition is satisfied, a post-processing rotation executing means D is executed in parallel to a pre-processing rotation executing means C. Accordingly, even if the pre-processing rotation is on the way, the post-processing rotation is executed. In this way, the rotation of a photosensitive body A is shortened and the service life can be prevented from becoming short.
