4.2.4 Parameter setting
POINT
The following encoder cables are of four-wire type. When using any of these
encoder cables, set [Pr. PC22] to "1 _ _ _" to select the four-wire type. Incorrect
setting will result in [AL. 16 Encoder initial communication error 1].
MR-EKCBL30M-L
MR-EKCBL30M-H
MR-EKCBL40M-H
MR-EKCBL50M-H
In the position control mode, the servo amplifier can be used by merely changing the basic setting
parameters ([Pr. PA _ _ ]) mainly.
As necessary, set other parameters.
4.2.5 Actual operation
Start actual operation after confirmation of normal operation by test operation and completion of the
corresponding parameter settings. Perform a home position return as necessary.
4.2.6 Trouble at start-up
CAUTION
Never adjust or change the parameter values extremely as it will make operation
unstable.
POINT
Using the optional MR Configurator2, you can refer to reason for rotation failure,
etc.
The following faults may occur at start-up. If any of such faults occurs, take the corresponding action.
