Configuration Parameter Description
b5-90 [EZsleep Unit] Sets the unit of measure for b5-92 [EZsleep Level]. When b5-90 = 1[0.1Hz units], the setting range of b5-91
[EZsleep Min Spd] is 0.0 to 590.0 Hz. When b5-90 = 0 [rpm], the setting range is 0 to 35400 min
-1
(r/min).
Note:
When you change b5-90, the value of b5-92 is not automatically updated.
b5-91 [EZsleep Min Spd]
This parameter sets the lower limit for PID output. The drive uses the largest value of b5-91, b5-34 [PID Out
Low Limit Level], and d2-02 [FRef Lower Limit] to internally set the lower limit of PID output. The b5-89
setting does not have an effect.
b5-92 [EZsleep Level] When the output frequency or motor speed is less than the value of b5-92 for longer than the value of b5-93
[EZsleep Time], the drive does to sleep.
b5-95 = 1 [EZsleep Wake Mode = Absolute] When the PID feedback is less than the value of b5-94 [EZsleep Wake Level] for longer than the time set in
b5-96 [EZsleep Wake Time], the drive restarts operation from sleep.
b5-95 = 0 [EZsleep Wake Mode = Setpoint Delta] When the PID feedback is less than the value set as the PID setpoint value minus b5-94 for the time set in
b5-96, the drive restarts operation from sleep.

*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. b5-91 is the EZ sleep level.
■ b5-01 PID Enable
No.
(Hex.)
Name Description
Default
(Range)
b5-01
(01A5)
PID Enable
Enables PID control.
0
(0,1)
0 : Disabled
1 : Enabled
The drive does D control on the difference between the feedback value and the PID setpoint output through U5-02
[PID Input].
■ b5-70 PID MainRefMode
No.
(Hex.)
Name Description
Default
(Range)
b5-70
(01E5)
PID MainRefMode
Sets the PID main reference mode.
0
(0, 1)
0 : PID only
The drive does D control on the difference between the feedback value and the PID setpoint output through U5-02
[PID Input].
1 : Fref + PID
The drive adds the frequency reference to the PID output. The drive does D control on the feedback output
through U5-06 [PID AdjustFeedback].
