Configuration Parameter
b5-92 [EZ Sleep Level]
b5-95 = 0 [EZ Wake-up Mode = Absolute]
b5-95 = 1 [EZ Wake-up Mode = Setpiont Delta]
Figure 11.38 EZ Sleep/Wake-up Operation: PID Output is Normal and b5-92 = 0.0 Hz
*1 Operation is determined by the setting values of b5-94 and b5-95.
*2 In the example, b5-92 is at the default setting of 0.0 Hz. In this scenario, b5-91 functions as the EZ sleep
level.

b5-01 PID Function Setting
(01A5)
0 : Disabled
1 : Enabled D=Fdbk
The drive performs D control on the difference between the feedback value and the PID setpoint output via U5-02
[PID Input].
2 : Enabled D=Fdfwd
The drive performs D control on the feedback output via U5-06 [PID AdjustedFeedback].
3 : Fref+PID D=Fdbk
The drive adds the frequency reference to the PID output. The drive performs D control on the difference between
the feedback value and the PID setpoint output via U5-02 [PID Input].
4 : Fref+PID D=Fdfwd
The drive adds the frequency reference to the PID output. The drive performs D control on the feedback output
via U5-06 [PID AdjustedFeedback].
5 : Enabled D=Fdbk2
6 : Enabled D=Fdfwd2
7 : Fref+PID D=Fdbk2
8 : Fref+PIDD=Fdfwd2
YASKAWA ELECTRIC SIEP C710617 01B YASKAWA AC Drive GA700 Technical Manual
The drive enters the sleep state when the output frequency or motor speed drops
below the value of b5-92 continuously for a time longer than the setting value of b5-
93 [EZ Sleep Time].
The drive resumes operation from the sleep state when the PID feedback has
dropped below the value of b5-94 [EZ Wake-up Level] for longer than the time
configured with b5-96 [EZ Sleep Time].
The drive resumes operation from the sleep state when the PID feedback has
dropped below the value defined as the PID setpoint value minus b5-94
continuously for the time configured with b5-96.
