Resistance/Inductance Autodetection (Detect_RL)

The EverCNC drive will try to detect values for motor resistance and inductance when the drive starts up (or when the Nominal_Current parameter changes).

This autodetection has limitations, so under some circumstances, it may calculate bad values. You may need to disable autodetection (Detect_RL) and manually enter in values for resistance and inductance.

Motor_R

(EtherCAT Object Index: 0x2005/6/4)

This parameter is specified in milliohms (mΩ).

From the manual (p.90, Manual_TitanioPlatinoVanadio_DS402_EN.pdfCANopen&EtherCAT DS402 Specification for ’Titanio-Platino-Vanadio’ EVER Drives)

This object sets the motor R (resistance) used for Motor Current Regulation. This value is used when Motor R,L detection function is disabled (bit#9 of Drive_Working_Settings_Extended object equal to 0).

The Nominal_Current of the Motor must be defined. 

Motor_L

(EtherCAT Object Index: 0x2005/7/4)

This parameter is specified in millihenries (mH)

From the manual (p. 90, Manual_TitanioPlatinoVanadio_DS402_EN.pdfCANopen&EtherCAT DS402 Specification for ’Titanio-Platino-Vanadio’ EVER Drives)

This object sets the motor L (inductance) used for Motor Current Regulation. This value is used when Motor R,L detection function is disabled (bit#9 of Drive_Working_Settings_Extended object equal to 0).

The Nominal_Current of the Motor must be defined.
