Chapter 12 Description of Parameter SettingsC2000

PID Compensation
Default: 0.0
Settings -100.0–100.0%
The PID compensation value = maximum PID target value × Pr. 08-17. For example, if the
maximum operaiton frequency Pr. 01-00 = 60.00 Hz, Pr. 08-17 = 10.0%, the PID compensation
value increases the output frequency 6.00Hz. 60.00Hz × 100.00% × 10.0% = 6.00Hz
Sleep Mode Function Setting
Default: 0
Settings 0: Refer to PID output command
1: Refer to PID feedback signal
0: The unit for Pr. 08-10 and that for Pr. 08-11 switch to frequency. The settings then are between
0–599.00 Hz.
1: The unit for Pr. 08-10 and that for Pr. 08-11 switch to percentage. The settings then are
between 0–200.00%.
Wake-up Integral Limit
Default: 50.0
Settings 0.0–200.0%
The wake-up integral limit for the drive prevents suddenly running at high speed when the drive
wakes up. The wake-up integral frequency limit = (Pr. 01-00 × Pr. 08-19%)
Reduces the reaction time from sleep to wake-up.
Enable PID to Change the Operation Direction
Default: 0
Settings 0: Operation direction cannot be changed
1: Operation direction can be changed
Wake-up Delay Time
Default: 0.00
Settings 0.00–600.00 sec.
Refer to Pr. 08-18 for more information.
PID Control Flag
Default: 0000h
Settings bit0 = 1, PID running in reverse follows the setting for Pr. 00-23
bit0 = 0, PID running in reverse follows PID’s calculated value
bit1 = 1, second decimal place of PID Kp
bit1 = 0, first decimal place of PID Kp
bit0 = 1: Valid when enables PID running in reverse (Pr. 08-21 = 1).
bit0 = 0, if the PID calculated value is positive, the direction is forward. If the PID calculated value
is negative, the direction is reverse.
There are three scenarios for sleep and wake-up frequency. Refer to following explanations:
