3. SIGNALS AND WIRING
3 - 3
(1) Using 3-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.
