Activate the “Motor identification” function and follow the instructions proposed by the INVERTER, then change the parameters
described below. The image shows the software screen on the PC.
Parameter
34.010 Control type
Open-loop asynchronous motor.
Set value = 100 (open-loop asynchronous motor)
34.020 Flying restart
Set value = 1 (enabled)
34.021 Flying restart time
Calculated by Inverter.
Set value = value calculated by INVERTER in ms
34.090
Speed controller K
P
Calculated by the inverter during the motor recognition phase. Reset it to 2000 after
motor recognition.
Set value = 2000 mA/rad/sec
34.091
Speed controller T
N
Calculated by the inverter during the motor recognition phase. Reset it to 7.5 seconds
after motor recognition.
Set value = 7.5 seconds
34.110
Slip trimmer
If set to
1
the function is enabled.
If set to
0
the motor performs as if connected to the mains.
If compensation is enabled, the system aligns the stator frequency with the rotor. As a
result, the actual motor rpm increase and are brought in line with the theoretical motor
nameplate rpm. The motor is supplied with the same voltage and frequency, but the
current increases and the rpm are brought to the nameplate data.
Set value = 1 (compensation for slippage)
Output signal variant for reading motor rpm (optional)
To have a 4-20 mA analogue output that indicates the motor rpm to the terminals X5-13 (Aout 0-20 mA) and X5-16 (A GND), set the
parameters below:
Parameter
4.100
Analogue output AO1
Selection of analogue output options.
In our case, to have an output proportional to the rpm, set 19.
Set value = 19 (actual rpm)
4.101
Minimum value of analogue
output AO1
Output signal at 0-20 mA.
To obtain a 4-20 mA signal with (4 mA = 0 motor rpm), follow the example: if motor rpm
are a maximum 2900, calculate:
2900 / 20 x 4 =
580
, which is the negative value corresponding to 0 mA from which to
start.
Therefore:
0 mA = - 580,
20 mA = 2900
Set value = - xxx (-580 in the example)
4.102
Maximum value of analogue output
AO1
Maximum rpm value for 20 mA.
Set value = xxxx (2900 in the above example)
