Easy Replacement of MR-J3 Series

Compatible mounting

When not changing the controller to SSCNET III/H controller MR-J4-B/MR-J4W2-B/MR-J4W3-B servo amplifier has J3 compatibility mode. By operating in J3 compatibility mode, MR-J4 series servo amplifier and MR-J3 series servo amplifier can be used together in a same system without changing the existing controller. * When the SSCNET III compatible products are in the system, the communication speed is 50 Mbps, and the function and the performance are equivalent to those of MR-J3. * Some functions may not be supported by the J3 compatibility mode. Refer to relevant Servo Amplifier Instruction Manual for details. The following new functions of MR-J4 series are available with J3 extension function of J3 compatibility mode. One-touch tuning function Advanced vibration suppression control Ⅱ Robust filter Machine resonance suppression filter (5 filters) SEMI-F47 function Tough drive function Drive recorder function Machine diagnosis function Power monitoring function Lost motion compensation function Parameters are automatically converted by changing MR-J3-B to MR-J4-B with MELSOFT MT Works2* 1 . Parameters of MR-J3-A are converted to those of MR-J4-A, using the parameter converter function of MELSOFT MR Configurator2* 1 . *1. Be sure to update your MT Works2 and MR Configurator2 to the latest version. Parameter conversion MR-J4-B/MR-J4-A has the same mounting dimensions* 1 with MR-J3-B/MR-J3-A. HG rotary servo motor series has the same mounting dimensions* 2 and uses the same option cables for the power, the encoder* 3 , and the electromagnetic brake as HF series or HC-RP/HC-UP series. *1. Mounting dimensions are smaller for servo amplifiers rated 200 V 5 kW, 400 V 3.5 kW, 200 V/400 V 11 kW, and 200 V/400 V 15 kW. *2. For replacing HA-LP series to HG-JR series, contact your local sales office for more detail. *3. HG-JR series of 11 kW to 55 kW uses a different encoder cable from HF-JP series.
