B112: kW without VFD (kW)
Enter the power consumption in kW before Axpert-Eazy variable frequency drive is installed. This is
used to calculate the energy saving with VFD.
B113: Currency Selection
Select the currency of the energy cost. The money saved using VFD is displayed in this currency.
B114: Energy Cost
Enter the energy cost here. This is used to calculate the money saved using VFD.
Note: Parameters B115 to B117 are not applicable to standard VFD and applicable only when the function is
enabled in factory parameters and the unit is provided for the variable voltage fix frequency source.
B115: Local Set Voltage (%)
Enter the output voltage in % of Motor voltage B102. This is applicable only when the unit is
configured to use as variable voltage fix frequency power supply.
B116: Output Voltage Reference Selection
6
Use this parameter to select the output voltage reference input.
When Local is selected, the output voltage is set using B115.
B117: Encoder Polarity
This is used to select Encoder polarity.
= 0: Forward
= 1: Reverse
B118: No Load Output Current (Amp)
Set the motor no load current. If the no-load motor current is not available, enter the current drawn by
the no-load motor when it runs on mains.
B119: Motor Overload Selection
Set the motor overload in percentage with respect to motor rated current which is set in B103. This is
reference for the inverse time motor overload characteristics. Changing this parameter can change
the inverse time motor overload characteristics.
GROUP – 2: MOTOR CONSTANT
B201: Automatic Tuning selection
This parameter allows the user to select the automatic tuning process. Select appropriate option for
the automatic tuning that matches the working conditions.
The basic parameter such as A501: Manual torque boost is adjusted apart from motor parameters
such as B202 ~ B211, Primary (stator) Resistance, Secondary (rotor) Resistance, Leakage
Inductance and Excitation (magnetizing) Inductance are adjusted.
Refer 4-3 Automatic Tuning & Adjustment for further detail.
= 1: Automatic tuning processes disable.
= 2: Stationary (Belt ON) (for V/F and V/F close loop)
The automatic tuning process is executed without rotating the motor. Select this option when it is
difficult to decouple the load from motor or the load is less than 10% or less.
