Basic Parameter setting
The basic parameter setting that always is to be checked or modified is listed below:
Para-

Name Default
setting
To be set Function
P1-01
Maximum Frequency
50 Hz Max freq. If P1-10, Motor rated speed,
≠ 0 unit is rpm instead of Hz.
P1-02
Minimum Frequency
0 Hz Min freq.
Set to some few Hz to ensure torque in motor. If P1-10, Motor rated
speed,
≠ 0 unit is rpm instead of Hz.
P1-03
Acceleration Time
5/30,0 sec Acceleration ramp time from 0 Hz to P1-09 (50 Hz)
P1-04
Deceleration Time
5/30,0 sec Deceleration ramp time from P1-09 (50 Hz) to 0 Hz
P1-07
Motor Rated Voltage
230/400 V
Put rated voltage of motor from motor nameplate in unit V
P1-08
Motor Rated Current
- Put rated current of motor from motor nameplate in unit A
P1-09
Motor Rated Frequency
50 Hz 50 Hz Put rated frequency of motor from motor nameplate in unit Hz
P1-12
Command Source
0 0
0: Control by digital and/or analog signals
1: Control from Keypad
P1-14
Parameter Access
0 201
Normally only parameters P1-01 to P1-14 are accessible. All other
parameters are accessible with this parameter put to 201.
P2-24 Switching Frequency
Drive
depending
Keep as low as possible. Higher value decreases audible noise in
motor but increase losses in drive.
P2-26 Spin Start Enable 1
0: Disabled
1: Enabled. The drive will attempt to determine if the motor is already
rotating, at what speed and direction on start up. The control of the
motor will start from the measuring. A delay of a few seconds will be
observed when starting the drive.
P4-01
V/F Characteristic
Select
0
0: Induction motors that require variable torque, for example fans
1: Induction motors that require constant torque, for example pumps,
conveyors and all heavy loads.
5.1 Digital start in one direction and one Preset or Analog setpoint
Start of drive is done by digital Start signal and set frequency is either a fixed preset speed or
an analog input signal on terminal 6. Analog signal can be either 0-10 V, 10-0 V, 4-20/20-4
mA. If 4-20 mA signal is used, then current should flow into terminal 6 and out from terminal
7.
