PID sleep functionality This function is controlled via a wait delay and a separate wake-up margin condition. With this function it is possible to put the VSD in “sleep mode” when the process value is at it’s set point and the motor is running at minimum speed for the length of the time set in [386]. By going into sleep mode, the by the application consumed energy is reduced to a minimum. When the process feedback value goes below the set margin on the process reference as set in [387], the VSD will wake up automatically and normal PID operation continues, see examples. PID sleep when less than minimum speed [386] If the PID output is equal to or less than minimum speed for given delay time, the VSD will go to sleep. Default: Range: Off Off, 0.01 –3600 s Communication information Modbus Instance no/DeviceNet no: 43371 Profibus slot/index 170/20 Fieldbus format Modbus format PID Activation Margin [387] The PID activation (wake-up) margin is related to the process reference and sets the limit when the VSD should wake-up/start again. Communication information Long, 1=0.01 s EInt NOTE: Menu [386] has higher priority than menu [342].

PID Steady State Test [388] In application situations where the feedback can become independent of the motor speed, this PID Steady Test function can be used to overrule the PID operation and force the VSD to go in sleep mode i.e. the VSD automatically reduces the output speed while at the same time ensures the process value. Example: pressure controlled pump systems with low/ no flow operation and where the process pressure has become independent of the pump speed, e.g. due to slowly closed valves. By going into Sleep mode, heating of the pump and motor will be avoided and no energy is spilled. PID Steady state test delay. NOTE: It is important that the system has reached a stable situation before the Steady State Test is initiated. Default: Range: Off Off, 0.01–3600 s Communication information Modbus Instance no/DeviceNet no: 43373 Profibus slot/index 170/22 Fieldbus format Modbus format 388 PID Stdy Tst StpA Off Long, 1=0.01 s EInt During the steady state test the PID operation is overruled and the VSD is decreasing the speed as long as the PID error is within the steady state margin. If the PID error goes outside the steady state margin the test failed and normal PID operation continues, see example. Default: 0 Range: 0–10000 in process unit Communication information Modbus Instance no/DeviceNet no: 43374 Profibus slot/index 170/23 Fieldbus format Modbus format 389 PID Stdy Mar Stp 0 A Long, 1=0.01 s EInt Example: The PID Steady Test starts when the process value [711] is within the margin and Steady State Test Wait Delay has expired. The PID output will decrease speed with a step value which corresponds to the margin as long as the Process value [711] stays within steady state margin. When Min Speed [341] is reached the steady state test was successful and stop/sleep is commanded if PID sleep function [386] and [387] is activated. If the Process value [711] goes outside the set steady state margins then the test failed and normal PID operation will continue, see Fig. 69. PID Steady State Margin [389] PID steady state margin defines a margin band around the reference that defines “steady state operation”.
