 Note:
1. The emergency stop warning message will appear if MD0 and MD1 are ON after power suppliers to
AC servo drive. If turn MD0 and MD1 to be OFF, the emergency stop warning message will
disappear automatically.
2. When the status is switched from 2 (MD1=OFF, MD0=ON) to 3 (MD1=ON, MD0=OFF), the
emergency stop warning message will appear. On the other hand, the emergency stop warning
message will also appear when the status is switched from 3 to 2. Therefore, no matter what status
you want to switch to, it is needed to switch to status 1 first to perform torque decrease (for example,
switch from 2 Æ1Æ3 or 3Æ1Æ2).
3. Ensure that MD0 and MD1 are set to ON state to enforce an emergency stop.
