a timer is started at a time 81 the vfd frequency reference has stopped decreasing but it is still out of the bounds of energy frequency parameter 102 at a time 82 the timer has exceeded the longer of either the energy delay open parameter 109 or the minimum baseblock time parameter 111 so the control 18 turns on the vfd output contactor 5 placing the system back to drive mode and starts a timer at a time 83 the timer has reached the value in the energy delay close parameter 110 and thus the control 18 commands the vfd 2 to leave the baseblock mode the vfd 2 then begins its speed search mode to start controlling an already spinning motor at a time 84 the vfd 2 has completed its speed search mode and the vfd output frequency is equal to the vfd frequency reference the present invention has been described with respect to flowcharts and block diagrams it will be understood that each block of the flowchart and block diagrams can be implemented by computer program instructions these program instructions may be provided to a processor to produce a machine such that the instructions which execute on the processor create means for implementing the functions specified in.
