High-function General-purpose Inverter 3G3RX-V1 User’s Manual (I578-E1)
Example
For a motor-to-encoder reduction ratio of 1 to 10, set the following parameters values.
• Number of Encoder Pulses (P011): 1,024
• Motor Gear Ratio Numerator (P028): 1
• Motor Gear Ratio Denominator (P029): 10
• Use this function to measure and automatically set the motor parameters required for the sensorless
vector control, 0-Hz sensorless vector control, or sensor vector control.
• To use the sensorless vector control, 0-Hz sensorless vector control, or sensor vector control
method, perform offline auto-tuning to measure the motor parameter values.
• If an Encoder disconnection (E60. / E70. ) or Overspeed (E61. /E71. ) error occurs, check the
encoder wiring and the parameter settings for the PG Board.
• Sensor vector control can be used only for the 1st control method.
• The measured motor parameter values will be set as 50-Hz data for one phase in 3-phase
Y-connection.
