No. Name Description Values
b5-92
<1>
EZ Sleep Level
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) + 1 Hz.
Default: 0.0 Hz
Range: 0.0 to
400.0 Hz
or 0 to 24000 RPM
<2>
b5-93
<1>
EZ Sleep Time
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.
Default: 5.0 s
Min.: 0.0
Max.: 1000.0
b5-94
<1> <1>
EZ Wake-up Level
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.
Default: 0.00%
Min.: 0.00
Max.: 600.00
b5-95
<1>
EZ Wake-up Mode
Sets how the wake-up level is determined.
0: Absolute
1: Setpoint Delta
Default: 0
Range: 0, 1
b5-96
<1>
EZ Wake-up Time
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.
Default: 1.0 s
Min.: 0.0
Max.: 1000.0
<1> Parameter is only effective when EZ Sleep is enabled by setting b5-89 to 1.
<2> Unit, range and resolution is determined by b5-90. Changing b5-90 will not automatically update the value of this parameter.

C1-01 to C1-04: Accel, Decel Times 1 and 2
Two different sets of acceleration and deceleration times can be set in the drive by digital inputs, motor selection, or switched
automatically.
Acceleration time parameters always set the time to accelerate from 0 Hz to the maximum output frequency (E1-04).
Deceleration time parameters always set the time to decelerate from maximum output frequency to 0 Hz. C1-01 and C1-02
are the default active accel/decel settings.
No. Parameter Name Setting Range Default
C1-01 Acceleration Time 1
0.0 to 6000.0 s
<1>
10.0 s
C1-02 Deceleration Time 1
C1-03 Acceleration Time 2
C1-04 Deceleration Time 2
<1> The setting range for the acceleration and deceleration times is determined by the accel/decel time setting units in C1-10. For example, if the time
is set in units of 0.01 s (C1-10 = 0), the setting range becomes 0.00 to 600.00 s.
Switching Acceleration Times by Digital Input
Accel/decel time 1 is active by default if no input is set. Activate accel/decel times 2, 3, and 4 by digital inputs
(H1-oo = 7 and 1A) as explained in Table 4.11.

1 0 C1-03 C1-04
Figure 4.16 shows an operation example for changing accel/decel. times. The example below requires that the stopping method
be set for “Ramp to stop” (b1-03 = 0).
