Note 1. After resolving the source of trouble, cool the equipment for approximately 30 minutes.
2. The following shows two stop methods of DB and SD.
3. This is applicable when [Pr. PA04] is set to the initial value. The stop system of SD can be changed to DB
4. For MR-J4-_A_ servo amplifier, quick stop or slow stop can be selected using [Pr. PD30].
5. The processing and stop systems are applicable only for the multi-axis servo amplifiers (MR-J4W_-_B_).
6. As the initial value, it is applicable only for [AL. 24] and [AL. 32]. All-axis stop can be selected using [Pr.
7. For MR-J4-_GF_ servo amplifier, quick stop or slow stop can be selected using [Pr. PD12]. (I/O mode
