Appendix C  FAQI. In the case of vector control 2 with encoder speed feedback or torque control, why did the inverter have too large running current or report E.oL1 error?  A: Check the software setup: A: (1) Check if the motor parameters are properly set; A; (2) Check if the number of pulses per turn of the encoder Pd.21 is properly set; A: (3) Check if the deceleration ratio between motor and encoder Pd.24 is properly set; A: (4) If the above three parameters are properly set, change the value of Pd.22. If it is 0, change it to 1; while if it is 1, change it to 0. Check the hardware connection: A: (1) Check if the PG card matches the encoder; A: (2) Check if the PG card and the encoder are properly connected, check if there is any loose connection or broken wire; A: (3) Check i...
