Internal Pid Calculation Frequency Command; Pid Feedback Rate Percentage - Delta C2000 series User Manual

Chapter 12 Description of Parameter SettingsC2000 Series
3) PID Feedback Rate Percentage ( Use PID, Pr08-00 ≠ 0 and Pr08-18=1)
When the PID feedback rate reaches the sleep level percentage, the VFD starts to count the sleep
time. The output frequency will also decrease. If the VFD exceeds the preset sleep time, it will go to
sleep mode which is 0 Hz. But if the VFD doesn't reach the sleep time, it will remain at the lower limit
(if there is a preset of lower limit.). Or it will remain at the lowest output frequency set at Pr01-07 and
wait to reach the sleep time then go to sleep mode (0 Hz).
When PID feedback value reaches the wake up percentagethe motor drive will start to count the
wake up delay time. Once reaches the wake up delay time, the motor drives starts the accelerating
time to reach PID frequency command
