(2) Using 1-phase 200 V AC to 240 V AC power supply for MR-JE-10B to MR-JE-100B
POINT
For MR-JE-_B servo amplifiers, the hot line forced stop function is enabled at
factory setting. For MR-J4-_B servo amplifiers, the hot line forced stop function
is disabled at factory setting.
If an alarm occurs, the hot line forced stop function outputs hot line forced stop
signals to all servo amplifiers before a communication to the controller is cut.
Then, the servo amplifiers will be in the [AL. E7.1 Controller forced stop input
warning] state, and the servo motors will decelerate to a stop.
The hot line forced stop function can be disabled with [Pr. PA27].
Configure the power supply circuit which turns off magnetic contactors of all
servo amplifiers after detection of alarm occurrence on the controller side at
alarm occurrence.
Connect the 1-phase 200 V AC to 240 V AC power supply to L1 and L3. One of
the connecting destinations is different from MR-JE-200B Servo Amplifier's.
You can use the neutral point of a 3-phase 400 V AC class power supply to
input a 1-phase 200 V AC class power supply to the servo amplifier. Refer to
app. 10 for details.
