10.10
Gain Over the PID Detection Value
Unit: 0.1
Settings
0.0 to 10.0
Factory Setting: 1.0
 This is the gain adjustment over the feedback detection value. Refer to PID control block diagram in
Pr.10.06 for detail.
10.12
PID Feedback Level Unit: 0.1
Settings 0.0 to 100.0% Factory Setting: 10.0
 When Pr10.12=0, PID feedback error detection is disable.
10.13
Detection Time of PID Feedback Unit: 0.1
Settings 0.1 to 300.0 sec Factory Setting: 5.0
 This parameter is used to set detection of the offset between set point and feedback.
 When the offset is higher than (the setting of Pr.10.12 X Pr.01.00) for a time exceeding the setting of
Pr.10.13, the AC motor drive will output a signal when Pr.03.00 is set to 16 and will act according to
Pr.10.20.
10.14
Sleep/Wake Up Detection Time Unit: 0.1
Settings 0.0 to 6550 sec Factory Setting: 0.0
10.15
Sleep Frequency Unit: 0.01
Settings 0.00 to 599.0 Hz Factory Setting: 0.00
10.16
Wakeup Frequency Unit: 0.01
Settings 0.00 to 599.0 Hz Factory Setting: 0.00
 When the actual output frequency
≤
Pr.10.15 and the time exceeds the setting of Pr.10.14, the AC motor
drive will be in sleep mode.
 When the actual frequency command > Pr.10.16 and the time exceeds the setting of Pr.10.14, the AC motor
drive will restart.
 When the AC motor drive is in sleep mode, frequency command is still calculated by PID. When frequency
reaches wake up frequency, AC motor drive will accelerate from Pr.01.05 minimum frequency following the
V/f curve.
 The wake up frequency must be higher than sleep frequency.
