PID Units Selection
Sets the display units for parameter b5-19, and monitors U5-01, U5-04 and
U5-99
0: WC (Inch of water)
1: PSI (Pounds per square inch)
2: GPM (Gallons per minute)
3: F (Degrees Fahrenheit)
4: CFM (Cubic feet per minute)
5: CMH (Cubic meters per hour)
6: LPH (Liters per hour)
7: LPS (Liters per second)
8: Bar (Bar)
9: Pa (Pascal)
10: C (Degrees Celsius)
11: Mtr (Meters)
12: Ft (Feet)
13: LPM (Liters per minute)
14: CMM (Cubic meters per minute)
15: “Hg (Inches of Mercury)
25: No unit
Default: 0
Range: 0 to 15; 25

Reverse Operation Selection
2 by PID Output
0: Zero limit when PID output is a negative value.
1: Reverse operation when PID output is a negative value
(Zero limit if the reverse operation is prohibited by b1-04).
Default: 1
Range: 0, 1

b5-89
(B89)
Sleep Method Selection
Determines how the drive sleeps and wakes-up when using PID.
0: Standard
1: EZ Sleep/Wake-up
Default: 0
Range: 0, 1
101
b5-90
(B90)
<2>
EZ Sleep Unit
Sets the unit, range, and resolution of parameters b5-91 and b5-92.
0: Hz
1: RPM (number of motor poles must be entered)
Default: 0
Range: 0, 1
101
b5-91
(B91)
<2>
EZ Minimum Speed
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.
Default: 0.0 Hz
Range: 0.0 to
400.0 Hz
or 0 to 24000 RPM
<3>
101
b5-92
(B92)
<2>
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) + 1Hz.
Default: 0.0 Hz
Range: 0.0 to
400.0 Hz
or 0 to 24000 RPM
<3>
102
b5-93
(B93)
<2>
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
102
b5-94
(B94)
<2>
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

EZ Wake-up Mode
Sets how the wake-up level is determined.
0: Absolute
1: Setpoint Delta
Default: 0
Range: 0, 1
102
b5-96
(B96)
<2>
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
102
<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.
