■ b5-93 EZsleep Time
No.
(Hex.)
Name Description
Default
(Range)
b5-93
(0B93)
RUN
EZsleep Time
Sets the length of time that the output frequency or motor speed must be less than b5-92 [EZsleep
Level] to enter Sleep Mode.
5.0 s
(0.0 - 1000.0 s)
■ b5-94 EZsleep Wake Level
No.
(Hex.)
Name Description
Default
(Range)
b5-94
(0B94)
RUN
EZsleep Wake Level
Sets the level at which the drive resumes operation when exiting Sleep Mode.
0.00%
(0.00 - 600.00%)
Note:
The values of b5-20 [PID Unit Selection], b5-38 [PID SP User Scale for Display], and b5-39 [PID SP User digits for Display] set the
units. When b5-20, b5-38, and b5-39 change, this parameter does not automatically update. Set this parameter again after you change
b5-20, b5-38, and b5-39 are changed.
• When b5-95 = 1 [EZsleep Wake Mode = Absolute]:
When b5-09 = 0 [PID Output Level Selection = Normal output], and the PID Feedback [H3-xx = F] is less than
the value of b5-94 for a time longer than the value of b5-96 [EZsleep Wake Time], the drive will exit sleep and
start operation again. When b5-09 = 1 [Reverse output], and the PID feedback is more than setting value of b5-
94 for a time longer than the setting value of b5-96, the drive will exit sleep and start operation again.
• When b5-95 = 0 [Setpoint Delta]:
When b5-09 = 0, and the PID feedback is less than the value of “PID setpoint value - b5-94” for a time longer
than the value of b5-96, the drive will exit sleep and start operation again. When b5-09 = 1, and the PID
feedback is more than the value of “PID setpoint value + b5-94” for a time longer than the setting value of b5-
96, the drive will exit sleep and start operation again.
■ b5-95 EZsleep Wake Mode
No.
(Hex.)
Name Description
Default
(Range)
b5-95
(0B95)
EZsleep Wake Mode
Sets the wake-up mode to use when exiting Sleep Mode.
1
(0, 1)
0 : Setpoint Delta
1 : Absolute
■ b5-96 EZsleep Wake Time
No.
(Hex.)
Name Description
Default
(Range)
b5-96
(0B96)
EZsleep Wake Time
Sets the EZ Wake-up time.
1.0 s
(0.0 - 1000.0 s)
When the PID feedback is less than the value of b5-94 [EZsleep Wake Level] continuously for the time set in b5-
96, the drive will exit sleep and start operation again.
◆ b6: DWELL FUNCTION
The Dwell function momentarily holds the output frequency at start and stop.
This prevents motor speed loss when you start and stop heavy loads. The Dwell function is also enabled when
backlash on the machine side causes sudden movement at the start of acceleration and deceleration.
At the start of acceleration, the drive uses the output frequency and acceleration time set for the Dwell function to
automatically operate at low speed to minimize the effects of backlash. Then, the drive can accelerate again. The
Dwell function operates the same for deceleration.
For conveyor applications, the Dwell function also lets the drive interlock the output frequency and a delay time
for the holding brake on the load side.
The Dwell function momentarily stops during acceleration to prevent a PM motor from stepping out. Figure 12.34
shows how the Dwell function works.
