Encoder status checking details
Code Description
BAS-20 Auto Tuning
Sets the auto tuning type to “ 3 (Enc Test) ” to check the encoder
connection.
The inverter operates in the Fx direction and accelerates to +20 Hz until
it decelerates to 0 Hz and continues operating in the Rx direction,
accelerating to -20 Hz.
BAS-20 parameter value is automatically changed to
“ None ” if a
connection error is not detected.
The “Enc reverse” message is displayed if the encoder connection is not
correct. If this happens, you can change the APO-05 (ENC Pulse Sel)
parameter setting to match the actual direction, or swap the two
encoder cables that are connected to the motor.
APO-01 ENC Opt Mode Sets the encoder option mode to “ 1 (Feed-back) ” .
APO-04 Enc Type Sel
Select an encoder type.
