Step 3 - Check low speed motor rotation direction without
load from keypad.
(See keypad diagram on previous page)
Press
RUN
/
STOP
key. 7-segment display will indicates 00.0 to 05.0. This number is the
frequency output value. The display will now become solid (not blinking) because the
inverter output is ON.
Check the operating direction of the motor.
IF the direction of the motor is incorrect:
Press
RUN
/
STOP
key, turn off the AC power supply. When the power indicator LED is
off, change over motor connections T1 and T2 for example.
Apply the power again, and then check the motor direction by pressing
RUN
/
STOP
key.
If rotation is correct press
RUN
/
STOP
key again.
Step 4 - Check full speed at 50Hz / 60Hz
Increase the frequency with , keys, press DATA/ENT to save this frequency.
Set frequency to 50Hz / 60Hz according to the above.
Press
RUN
/
STOP
key; check that the motor accelerates smoothly to full speed.
Press
RUN
/
STOP
key; check that the motor decelerates smoothly to zero speed.
Step 5 - Other settings
For other functions, please refer to
iDrive
EDX user manual.
Example:
Frequency Upper Limit (Hz)…………………………... P. 4-9
Frequency Lower Limit (Hz)…………………………….P. 4-9
Acceleration time (s)…..………………………………… P. 4-10
Deceleration time (s)…..………………………………… P. 4-10
Control mode (Vector, V/F)……...………………………P. 4-10
Motor rated current (A)….………………………………P. 4-13
Step 6 - Vector Mode Settings
If
iDrive
is required to run in Vector Mode (A06 = 001), the motor parameters need to be set.
The required data should found on the motor rating plate. (Motor kW = 0.75
¯
HP)
The parameters to set for vector operation are:
Motor Rated Current (Amps) (b09) See page 4-13
Motor Rated Voltage (Volts) (b10) See page 4-13
Motor Rated Frequency (Hz) (b11) See page 4-13
Motor Rated Power (KW) (b12) See page 4-13
Motor Rated Speed (RPM) (b13) See page 4-13
Additional Vector Mode Settings to adjust for optimum performance are:
Torque boost gain (b14) See page 4-13
Slip compensation gain (b15) See page 4-14
Low Frequency Voltage Compensation (b16) See page 4-14
