ME300
it remains at the lower frequency limit (if there is a preset lower limit.), or it remains at the minimum
output frequency set at Pr.01-07 and waits until it reaches the sleep time before it going into sleep
mode (0Hz). When the PID calculated Frequency command reaches the wake-up frequency, the
drive starts to count the wake-up delay time. Once it reaches the wake-up delay time, the drive
starts to catch up to reach the PID Frequency command value by the acceleration time.
3) PID Feedback Rate Percentage (Use PID, Pr.08-00 ≠ 0 and Pr.08-18 = 1)
When the PID feedback value reaches the sleep level percentage, the drive starts to count the
sleep time and the output frequency starts to decrease. If the drive exceeds the preset sleep time,
then the drive is in sleep mode (0 Hz). If the drive does not reach the preset sleep time, it remains
at the lower frequency limit (if there is a preset of lower limit.), or it remains at the minimum output
frequency set for Pr.01-07 and waits until it reaches the sleep time before going into sleep mode
(0 Hz).
When the PID feedback value reaches the wake-up percentage, the drive starts to count the
wake-up delay time. Once it reaches the wake-up delay time, the drive starts to catch up to reach
the PID Frequency command value by the acceleration time.
Example 01: PID negative feedback
Pr.08-10 must > Pr.08-11
30kg is the reference
Set the parameter:
Pr.03-00 = 5 (AVI is PID feedback)
Pr.08-00 = 1 (PID
negative feedback: AVI
simulation input function select)
Pr.08-10 = 40% (Sleep reference:
12kg = 40%*30kg)
Pr.08-11 = 20% (Wake-up reference:
6kg = 20%*30kg)
Case 01: If feedback >12kg, frequency decreases.
Case 02: If feedback <6kg, frequency increases.
