APPLICATIONS OF Σ-SERIES PRODUCTS3.8.4 Using Regenerative Units1481) Connect the alarm output (ALM) terminals for the three Servopacks in series to enablealarm detection relay 1Ry to operate. This is because ALM is a logical complement out-put signal, so the output transistor is turned OFF when the system enters an alarm state.2) Multiple servos can share a single MCCB or noise filter. Always select a MCCB or noisefilter that has enough capacity for the total power capacity (load conditions) of those ser-vos. For details, refer to page 142.MCCB Noise filter3.8.4 Using Regenerative UnitsNote Regenerative unit can be applied only to 200V 30W to 200W (types DR2-A3A,A5A, 01A, 02A). For 200V 400W, 750W and all types of 100V, regenerative unitcannot be used.1) “What is a Regenerative Unit?”A regenerative unit is designed to safely consume electric energy that is generated whenthe servomotor is rotated by the load.Servopack Electric energyForceEnergyconsumption Regenerative unit3
