Motor Parameter Selection
•Set this parameter according to your motor.
•To use several motors with a single Inverter in the "VC", "special VP", or "free V/F setting" control
mode, calculate the total capacity of the motors and select the closest value in the motor capacity
selection.
•When automatic torque boost is used, improper setting of this parameter may result in torque
reduction or motor hunting.
•The motor parameters for "sensorless vector control", "0-Hz sensorless vector control", or "sensor
vector control" can be selected from the following three types:
•Motor parameter of a standard motor
•Motor parameter measured by offline auto-tuning
•Arbitrarily set motor parameter
•For 3rd control, motor parameters specified for 1st control are used.
*1. For 1st control A044, all items (00 to 05) are selectable. However, for 2nd control A244 and 3rd control A344,
the selectable range is 00 to 04, and 00 to 01, respectively. For ND the selectable range is 00 to 02.
*2: Convert moment of inertia J into motor shaft data. The larger the J value, the faster the response, resulting in
a steep torque rise; the smaller the J value, the slower the response, resulting in a gradual torque rise. After
setting the J value, adjust the response speed in speed response H005/H205.
