(4) PAR_46(Encoder type setting)
“EnDat” and “SIN/COS” are displayed when the IV5 EnDat option board is equipped to
inverter. Set the parameter according to the following table.

(5) PAR_47(Encoder tuning selection)
PAR_47 will be displayed only if you have set encoder type of PAR_46 to "EnDat
”. It is
calculated zero point of encoder and offset of motor magnetic pole. If you have installed an
inverter for the first time, or if you have replaced the motor / encoder, you must set
PAR_47
to
“Yes”. After encoder tuning, it will be set to “No” automatically. After setting
PAR_47 to
"Yes", the first operation is the test operation for tuning. Therefore the motor may generate
noise and vibration. During encoder tuning, Anti-Rollback function does not work.

(6) PAR_58(EnDat encoder direction setting)
Set PAR_58 to CW in the case encoder
’s A-phase is SIN input of option board and
encoder
’s B-phase is COS input of option board. Change
PAR_58 from CW to CCW in the
case encoder
’s A-phase is COS input of option board and encoder’s B-phase is SIN input
of option board. PAR_58 is EnDat encoder direction setting .
