4.6 Basic Drive Setup Adjustments
Sets the motor nameplate full load current in amperes (A).
Calculate and set the motor rated slip based on the rated speed described on
the motor nameplate.
Motor rated slip = Motor rated frequency [Hz] - Rated speed [r/min] x No. of
motor poles / 120.
Set motor no-load current at rated voltage and rated frequency.
Contact the motor manufacturer to get the no-load current. This information is
not usually written on the motor nameplate.
The default no-load current is for a Yaskawa 4-pole motor.
Displayed only when OLV control mode is selected. Set the number of motor
poles described on the motor nameplate.
This value is automatically set during Auto-tuning. When regular Auto-
Tuning is not possible, contact the motor manufacturer to find out the
resistance between lines (T-lead to T-lead). If using the Motor Test Report,
calculate resistance between lines as follows:
E-Type Insulation: Test Report value for line resistance at 75 °C at 0.92 ohms
B-Type Insulation: Test Report value for line resistance at 75 °C at 0.92 ohms
F-Type Insulation: Test Report value for line resistance at 115 °C at 0.87 ohms
Set the amount of voltage drop due to motor leakage inductance at base
frequency and motor rated current.This value should be set when using a high-
speed motor or another type of motor that has a relatively small amount of
inductance. Contact the motor manufacturer to get the motor leakage
inductance, as this information is not usually written on the motor nameplate.
This value is automatically set during rotational Auto-Tuning.
This value is automatically set during rotational Auto-Tuning.
Displayed only when using Open Loop Vector Control. It is not necessary to
set this parameter, but it may require adjustment under the following
circumstances:
Large amount of torque loss relative to motor bearings
Fan and pump type applications with a large amount of torque loss
The amount of mechanical loss will be reflected in the amount of torque
compensation.
Displayed only when using V/f Control. Increase the motor iron loss in watts
in order to increase the accuracy of torque compensation.
Sets the motor rated power in kilowatts (kW). This value is automatically set
during Auto-Tuning in units of 0.01.
Set to the motor iron saturation coefficient at 130% of magnetic flux. This
value is automatically set during rotational Auto-Tuning.
