control to a safe stop. See parameters AFN-46 (Load
Inertia), AFN-52 (Decel Rate) and AFN-53 (Decel
Percentage) to fine tune the operation of this function.
Note: This function can only be applied to
applications that have a high enough inertia to
provide enough stored energy to complete the
deceleration profile. Deceleration time will depend
on available load inertia.
If line power returns and the drive has a valid run
command the drive will accelerate the load back to its
appropriate speed. There is a delay of 2 – 3 seconds
after line power has returned before the drive will
respond. If a Stop command is made, the drive will
coast to a stop.
FUN-29: Line Frequency
This parameter sets the value of the incoming line
frequency.
☞
Caution: This parameters will affect the settings
of other parameters such as Max frequency, Base
frequency, and Upper limit. To set these related
frequencies differently than the line frequency, the
user should set these parameters manually AFTER
setting FUN-29.
FUN-30: Maximum Frequency
FUN-31: Base Frequency
FUN-32: Starting Frequency
FUN-30 [Maximum Frequency] is the highest
frequency the drive will output.
CAUTION
Consult with the motor manufacturer before
exceeding the base speed of the motor. Verify that
the driven equipment can operate at the
maximum speed set.
FUN-31 [Base Frequency] is the frequency where the
drive outputs full motor rated voltage. This parameter
is normally set to 50Hz or 60Hz. When using a 60Hz
motor, set this parameter to 60Hz.
FUN-32 [Starting Frequency] is the frequency where
the drive starts to output voltage. For example, if FUN-
32 it is set to 5Hz, the drive starts running when the
reference frequency is 5 Hz.
Caution: Note that these functions are reset when
FUN-29 [Line Frequency] is set.
Caution: Note that improper setting of FUN 31
[Base Frequency] can cause overload trips and lack
of motor torque.
