<1> Unit and resolution are determined by b5-20, b5-39 and b5-46. Internally limited to b5-38. Changing b5-20, b5-38 and b5-39 will not automatically
update the value of this parameter.
<2> Parameter is only effective when EZ Sleep is enabled by setting b5-89 to 1.
<3> Unit, range and resolution is determined by b5-90. Changing b5-90 will not automatically update the value of this parameter.

YASKAWA SIEP YAIP1U 01C AC Drive - P1000 Technical Manual
Description
Sets the PID minimum speed and integral lower limit.
The internal value is lower limited to the higher setting between b5-34 and
d2-02.
The drive will go to sleep when the drive output frequency (or speed) is at or
below this level for the time set in b5-93.
This parameter is internally lower limited to b5-91 (EZ Min Speed) + 1Hz.
The drive will go to sleep when the drive output frequency is at or below the
level set to b5-92 for the time set in this parameter.
When b5-95 is set to 0 (Absolute), the drive wakes-up when the PID Feedback
(H3-oo = 20) drops below this level for the time set in b5-96.
For reverse-acting, the PID Feedback must be above this level for the time set
in b5-96.
When b5-95 is set to 1 (Setpoint Delta), the drive wakes-up when the PID
Feedback (H3-oo = 20) drops below the PID Setpoint minus this level (for
normal acting PID) for the time set in b5-96.
For reverse-acting, Wake-up level is PID Setpoint plus this level. The PID
Feedback must be above the wake-up level for the time set in b5-96.
Sets how the wake-up level is determined.
0: Absolute
1: Setpoint Delta
The drive will wake up when the PID Feedback drops below the b5-94, EZ
Wake-up Level for the time set in this parameter.
Description
Parameters b6-01 and b6-02 set the frequency to hold and the time to maintain
that frequency at start.
Parameters b6-03 and b6-04 set the frequency to hold and the time to maintain
that frequency at stop.
