Drive Safety integrated AC servo amplifier

<MR-J3-DS 0.1 kW to 55kW>

Safety logic unit <MR-J3-D05>

The MR-J3-DS Drive Safety integrated AC servo amplifier (SSCNET

IE compatible) and MR-J3-D05 safety logic unit are newly added to

the MELSERVO-J3 series.

Safety functions of the MR-J3-DS and MR-J3-D05 are certified for

IEC/EN 61508 SIL 2, EN 62061 SIL CL 2 and EN ISO 13849-1 PL d

(Category 3) by a Certification Body (TUV Rheinland).

As a safety function, MR-J3-DS has an integrated Safe torque off

(STO) function. Safe stop 1 (SS1) function can be realized by

combining MR-J3-DS with MR-J3-D05. These functions contribute

to improvement of safety in the user's system, making it easy to

obtain third-party certification.

If MR-J3-DB is currently used in a user's system, it can be easily

replaced by the MR-J3-DS since both of these servo amplifiers use

the same cables and connectors. Also, the MR-J3-DS lineup

contains fully closed loop control system versions.

■ Features

• MR-J3-DS and MR-J3-D05 meet IEC/EN 61508 SIL 2, EN 62061 SIL CL 2 and EN ISO 13849-1 PL d (Category 31 Only the

Safe torque off (STO)*1 function is integrated into the MR-J3-DS. The MR^J3-D05 contains both Safe stop 1 (SS1) and Safe

torque off (STO)*1 functions.

• User's system can satisfy stop category 0*2 by using the Safe torque off (STO) function*1.

• User's system can satisfy stop category 0 and 1*2 by using the Safe torque off (STO) and Safe stop 1 (SS1) functions*1.

• Mounting, wiring and connectors of MR^J3-DS are compatible with those of MR-J3-DB. Thus, MR-J3-DB can be easily

replaced by the MR-J3-DS using the existing connections. The safety functions are accessible via the new CN8 connector on

the MR-J3-DS.

*1. Refer to EN IEC 61800-5-2 for details of Safe torque off (STO) and Safe stop 1 (SS1) functions.

*2. Refer to EN IEC 60204-1 for details of stop category.

Notes: 1. For prevention of electric shock during maintenance or for protection during servo amplifier fault, be sure to connect a magnetic contactor

(MC) between the main power supply and L1, L2 and L3 of the servo amplifier or converter unit.

2. Connect the STO switch signal and forced stop 2 (EM2) signal in connector CN3 of the servo amplifier in addition to the connection with

the safety logic unit (MR-J3-D05).

3. Safety logic unit (MR-J3-D05) has 2 independent systems (A-axis and B-axis).

4. All safety-related components such as relays, sensors, etc., must meet the applicable safety standards.

5. Perform risk assessment and safety level certification on the entire machine/system.
