Configuration Parameter Description
b5-90 [EZ Sleep Unit] 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 Minimum Speed] is 0.0 to 590.0 Hz. When b5-90 = 1 [rev/min] , 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 [EZ Minimum Speed]
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.
b5-92 [EZ Sleep Level] 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.
b5-95 = 0 [EZ Wake-up Mode = Absolute] When the PID feedback is less than the value of b5-94 [EZ Wake-up Level] for longer than the time set in b5-96
[EZ Sleep Wake-up Time] , the drive restarts operation from sleep.
b5-95 = 1 [EZ Wake-up Mode = Setpiont 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.

PID Mode Setting
Sets the type of PID control.
0
(0 - 8)
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)
Enables PID control. The drive performs D control on the feedback output via U5-06 [PID Fdbk-Diff PID Fdbk] .
3 : Fref + PID Trim
Enables PID control. 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 Trim (D on feedback)
