Y2: PID Sleep and Protection
■
Sleep Function
The Sleep Function uses the monitor data set in
Y2-01 [Sleep Level Type]
to know if the drive is necessary in the
system and turn off the drive.
This function helps to save the energy and prevent the deterioration on the motor.
*1
When
Y2-01 = 5 [Output Frequency (non-PID)]
, the drive will ignore the Start Level set in
Y1-04 [Sleep Wake-
up Level]
. Set
Y2-02
> 0 to enable the Sleep Function. The drive will enable the Sleep Function regardless of the
b5-01
setting or the status of the MFDI set for
H1-xx = 19 [PID Disable]
.
Sleep Activation Level and Sleep Level
•
Sleep Activation Level:
This level sets when the Sleep Function should start operation. You can use
Y2-04 [Sleep Activation Level]
or
Minimum Speed (the largest value from
d2-02
,
Y1-06
, and
Y4-12
) to set this level.
When the output frequency increases to more than the Sleep Activation Level, the Sleep Function will start to
monitor the system.
•
Sleep Level:
This is the level that the drive uses to go to sleep (stop). You can use
Y2-02 [Sleep Level]
or Minimum Speed to set
this level.
Delta to Setpoint Entry for Sleep Wake-up Level
Delta to Setpoint Entry lets you set
Y1-04 [Sleep Wake-up Level]
relative to the current setpoint and set a PID setpoint
when PID is not active.

Description
Absolute
The value set for
Y1-04
represents the feedback level that will wake-up the drive. You can
set
Y1-04
as an absolute value.
Delta to Setpoint
When the left-most digit changes to a Δ (delta), you can set a Sleep Wake-up Level relative
to the setpoint.
The effective Wake-up Level changes when
b5-09
changes:
•
b5-09 = 0
:
“
Setpoint -
Y1-04
”
•
b5-09 = 1
:
