Main circuit power supply selection
Select a voltage to be connected to the main circuit
power supply with an MR-J4W2-0303B6 servo amplifier.
0: 48 V DC
1: 24 V DC
When using 24 V DC for the main circuit power supply,
set "1" to this digit.
The setting of this digit in the J3 compatibility mode is
the same as the MR-J3W-0303BN6 servo amplifier. Set
it with [Pr. Po04]. For details, refer to "MR-J3W-0303BN6
MR-J3W-_B Servo Amplifier Instruction Manual".
This digit is not available with MR-J4W_-_B 200 W or
more servo amplifiers.
The characteristics of the servo motor vary depending on
whether 48 V DC or 24 V DC is used. For details, refer to
"Servo Motor Instruction Manual (Vol. 3)".
