Y1-40: Maximum Speed
No.
(Hex.)
Name Description
Default
(Range)
Y1-40
(3C27)
RUN
Maximum Speed Sets the maximum speed. 0.0 Hz
(0.0 - 416.0)
Note:
This parameter is not effective when Y1-40 = 0.0 Hz or Y1-40 > E1-04 [Maximum Output Frequency] × d2-01 [Frequency Reference Upper
Limit] .

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.
Parameter/Condition Delta Entry Absolute Entry

Table 5.66 Absolute Mode and Delta to Setpoint Mode
Entry Mode Keypad Display 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 :
“
Se Y1-04
”
