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 Æ 1Æ 3 or 3 Æ 1 Æ 2).

3)Ensure that MD0 and MD1 are set to ON state to enforce an emergency stop.
