4 SYSTEM START-UP
Many operation methods were designed into the PDA/E/H Series inverter. Here in this section, teaching you how to start
running the inverter by simplest operation method.
4.1 Reset & Initialize the inverter
When you first receiving the inverter, and not sure of the parameter value inside the inverter, please execute
Memory
Initialization
. The initialization sequence is first set
Pr.94=1(refer to section 3 and 5.3)
, then change to
ALM
mode
until display show
0. xx. T
hen push
STOP/RESET
key to start executing
software reset
and
memory initialization.
Or, after Pr.94=1, then connect
RST
terminal to
DCOM
, and then Inverter will execute hardware RESET immediately.
After memory initialized, most parameters (marked with TYPE: R/W in Table 5.1) will be preload to the default values.
4.2 Setup Basic Motor Parameter
Firstly, before starting, basic V/F curve parameters must setup first. Refer to section 5.4, the description of Pr.09, Pr.10,
Pr.11, Pr.15, Pr.16 and Pr.88.

Note: If Auto-Tuning had been executed, Pr.09 may be altered automatically.
Secondly, set motor rating is calculated from:
4.3 PDA series Operation Mode Selection
For PDA series only, through Pr.67 selection, the inverter can operate under the following 5 different modes:
Operation Mode
Description
Series
Model 0
Standard V/F (I)
PDA/PDE/PDH
Model 1
Standard V/F (II)
PDAN/PDA/PDH
Model 2
Sensor-Less (I)
PDA
Model 3
Sensor-Less (II)
PDAN/PDA
Model 4
Power-Control Mode
PDAN/PDA
4.3.0 Standard V/F (I) (For PDA/PDE/PDH)
Pr.67=0:
The inverter delivers Sine PWM voltage waveforms to the motor winding. The current signal is used for
protection only. Output current waveform is not compensated by the feedback current signal.
Note: PDE series also operate under this mode.
4.3.1 Standard V/F (II) (For PDAN/PDA/PDH)
Pr.67=1:
The inverter delivers Sine PWM waveform to motor, and check AC side output current. The distortion of
AC side current waveform due to IGBT dead time effect will be compensated in order to minimize torque ripple.
4.3.2 Sensor-Less (I) (For PDA)
Pr.67=2:
When the inverter is running, it checks the output voltage, output current and the phase angle continuously.
If the motor speed changes because of loading effect, the inverter can modify its output frequency automatically.
4.3.3 Sensor-Less (II) (For PDAN/PDA)
Pr.67=3:
Similar to Sensor-Less (I), the inverter operates under Sensor-less control algorithm.
Moreover, extra boost voltage is added in order to decrease the motor slip when running at low speed.
