4.12 Fan and Pump Application Preset Details
<1> Unit, range and resolution is determined by b5-90. Changing b5-90 will not automatically update the value of this parameter. Range is 0 to 24000
RPM when b5-90 is set to 1.
b5-92: EZ Sleep Level
n
When the drive output frequency (or speed) is at or below this level for the time set in b5-93, the drive will go to sleep.
The internal lower limit of this parameter is b5-91 (EZ Min Speed) + 1 Hz.
No.
b5-92
<1> Unit, range and resolution is determined by b5-90. Changing b5-90 will not automatically update the value of this parameter. Range is 0 to 24000
RPM when b5-90 is set to 1.
b5-94: EZ Wake-up Level
n
If 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 has to be above this level for the time set in b5-96.
If 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 has to be above the wake-up level for the time set in b5-96.
No.
b5-94
<1> Unit and resolution are determined by b5-20, b5-39, and b5-46. Internally limited to b5-38. Changing b5-20, b5-38 and b5-39 will not automatically
update the value of this parameter.
d2-01: Frequency Reference Upper Limit
n
Sets the maximum frequency reference as a percentage of the maximum output frequency. This limit applies to all frequency
references.
Even if the frequency reference is set to a higher value, the drive internal frequency reference will not exceed this value.
No.
d2-01
d2-02: Frequency Reference Lower Limit
n
Sets the minimum frequency reference as a percentage of the maximum output frequency. This limit applies to all frequency
references.
If a lower reference than this value is entered, the drive will run at the limit set to d2-02. If the drive is started with a lower
reference than d2-02, it will accelerate up to d2-02.
No.
d2-02
L2-01: Momentary Power Loss Operation Selection
n
When a momentary power loss occurs (DC bus voltage falls below the level set in L2-05), the drive can automatically return
to the operation it was performing prior to the power loss based on certain conditions.
