EZ Sleep/Wake-up Functionality
Set b5-89 = 1 [Sleep Method Selection = EZ Sleep/Wake-up] to enable the EZ Sleep/Wake-up function.
Note:
• When b5-89 = 0 [Sleep Mode Selection = Standard], the EZ Sleep function and related parameters are disabled. Parameter b5-91 [EZ Sleep
Minimum Speed] is not included in this rule.
• Set b5-89 = 1 to disable b5-15 [PID Sleep Function Start Level].
Setting Parameter
b5-90 [EZ Sleep Unit]
b5-91 [EZ Sleep Minimum Speed]
b5-92 [EZ Sleep Level]
b5-95 = 0 [EZ Sleep Wake-up Mode = Absolute]
b5-95 = 1 [EZ Sleep Wake-up Mode = Setpoint Delta]
Figure 12.38 EZ Sleep/Wake-up Operation: PID Output is Normal and b5-92 = 0.0 Hz
*1 The values of b5-94 and b5-95 set operation.
*2 In the example, b5-92 is at the default setting of 0.0 Hz. Parameter b5-91 is the EZ sleep level.

b5-01 PID Mode Setting
(01A5)
0 : PID control disabled
1 : Standard
Enables PID control. The drive performs D control on the difference between the feedback value and the PID setpoint
output via U5-02 [PID Input].
2 : Standard (D on feedback)
YASKAWA SIEPC71061737D GA800 Drive Technical Reference
Sets the unit of measure for b5-92 [EZ Sleep Level]. When b5-90 = 0 [0.1Hz units], the setting range of b5-91
[EZ Sleep Minimum Speed] is 0.0 to 590.0 Hz. When b5-90 = 1 [rev/min], the setting range is 0 to 35400 min-
(r/min).
Note:
When you change b5-90, the value of b5-92 is not automatically updated.
This parameter sets the lower limit for PID output. The drive uses the largest value of b5-91, b5-34 [PID Output
Lower Limit], and d2-02 [Frequency Reference Lower Limit] to internally set the lower limit of PID output. The
b5-89 setting does not have an effect.
When the output frequency or motor speed is less than the value of b5-92 for longer than the value of b5-93 [EZ
Sleep Time], the drive does to sleep.
When the PID feedback is less than the value of b5-94 [EZ Sleep Wake-up Level] for longer than the time set in
b5-96 [EZ Sleep Wake-up Time], the drive restarts operation from sleep.
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.
