Chapter 12 Description of Parameter Settings
ME300
12.1-08-7

08-13
PID feedback signal error deviation level
Default: 10.0
Settings 1.0–50.0%

08-14
PID feedback signal error deviation time
Default: 5.0
Settings 0.1–300.0 sec.

08-15
PID feedback signal filter time
Default: 5.0
Settings 0.1–300.0 sec.
 When the PID control function is normal, it should calculate the value within a period of time that
is close to the target value.
Refer to the PID control diagram for details. When executing PID feedback control, if |PID
reference target value – detection value| > Pr.08-13 PID Deviation Level and exceeds Pr.08-14
setting, it is judged as a PID control fault, and the multi-function output MO = 15 (PID feedback
error) activates.

PID Compensation Selection
Default: 0
Settings
0: Parameter setting
1: Analog input
 0: The setting for Pr.08-17 gives the PID compensation value.

08-17
PID Compensation
Default: 0
Settings
-100.0–100.0%
 The PID compensation value = maximum PID target value × Pr.08-17. For example, if Pr.01-00
the maximum operation frequency = 60 Hz, and Pr.08-17 = 10.0%, the PID compensation value
increases the output frequency 6.00 Hz. 60.00 Hz × 100.00% × 10.0% = 6.00 Hz
08-18
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
0.00–599.00 Hz.
 1: The unit for Pr.08-10 and that for Pr.08-11 switch to percentage. The settings then are between
0.00–200.00%.

08-19
Wake-up Integral Limit
Default: 50.0
Settings 0.0–200.0%
 Reduces the reaction time from sleep to wake-up.
 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%)
