(5) PID automatic switchover control (Pr.127)
 The system can be started up without PID control only at a start.
 When the speed is set to Pr.127 PID control automatic switchover speed, the drive unit starts up without PID control from a
start until rotation speed is reached to the set speed of Pr.127, and then it shifts to PID control. Once the system has
entered PID control operation, it continues PID control even if the rotation speed falls to or below Pr.127.

(6) PID monitor function
 The PID control set point, measured value and deviation value can be displayed on the operation panel and output from
terminal FM.
 Integral value indicating a negative % can be displayed on the deviation monitor. 0% is displayed as 1000. (The deviation
monitor cannot be output from the terminal FM.)
 For each monitor, set the following value in Pr.52 DU/PU main display data selection and Pr.54 FM terminal function selection.
