5.3.2 Initialize data into ALL parameters (for PDAN series only)
Follow the process to execute memory initialization
Step 1:
Write Pr.95 = 0, and Pr.94 = 249
Step 2:
Execute "ALM" RESET
or Step 2:
Execute Hardware RESET
or
Step 2:
Execute Power-On RESET
After initialization process, all of data in EAROM memory will change to the DEFAULT values listed in the
PARAMETERS LIST Table.
5.4 Description of All Parameters
Pr.00 MAIN_SPEED_SET
Pr.00 is the Main Speed memorized in EAROM. If SPEED_SELECT=0, this MAIN_SPEED_SET parameter will be
used as the desired frequency source.
Pr.01 MAIN_ACC_TIME
Pr.02 MAIN_DEC_TIME
Pr.01 & Pr.02 are the preset ACC & DEC time while inverter running. The definition of the Pr.01 (ACC) is "
the period
of time from 0.0Hz ramp up to Pr.15
”. The definition of the Pr.02 (DEC) is "
the period of time from Pr.15 ramp
down to 0.0Hz
”.
Pr.03 DI5 FUNCTION SELECT (Refer to Section 8)
Defines the function for input terminal DI5 (or the terminal marked with “
RUN
”).
Pr.04 DI6 FUNCTION SELECT (Refer to Section 8)
Defines the function for input terminal DI6 (or the terminal marked with “
REV
”).
Pr.05 BRAKE FREQUENCY
While deceleration to stop, if the output frequency is lower than this parameter, then DC current injection braking start
action.
Pr.06 BRAKE VOLTAGE
While braking starts, this parameter defines the Voltage level of DC injection. This parameter is defined as percent of
the input voltage.
Pr.07 BRAKE TIME
This parameter defines the DC injection braking time.
Note: DC injection braking time = Pr.07 – Pr.08
Pr.08 BRAKE DELAY TIME
While deceleration, if output frequency is lower than braking frequency (Pr.05), the output frequency remains and
output voltage will gradually drop down to the brake voltage (Pr.06) then start DC injection brake process.

is the time when STOP signal input.
Point-B
is the time when output HZ = Pr.05, or when EMS is ON.
Point-C
is the time when DC voltage (Pr.06) feed into the motor.
Point-D
is the time when injection brake period of Pr.07 is complete.
