Servo amplifier

Servo amplifier
MR-J2S-30A(4)/B(4) or larger
(5) 3-phase 200V and 3-phase 400V 11 to 22kW
(7) 3-phase 400V 2kW or smaller
(6) 3-phase 200V and 3-phase 400V 30kW or larger
1. The 11kW or larger capacity does not have a built-in regenerative resistor.
2. This is for the MR-RB137 (for 200V) and MR-RB138-4 (for 400V). For the MR-RB137 and MR-RB138-4, one set contains three units (tolerable wattage 3900W).
3. Remove the short bar across P-P1 when using the DC reactor. Do not remove the short bar when using the optional regeneration unit.
4. Remove the short bar across P1-P2 when using the DC reactor. Do not remove the short bar when using the optional regeneration unit.
5. Always connect the terminator (MR-A-TM) to CN5B.
6. The phases of the power supply connected to L11 and L21 on the converter unit and servo amplifier must always match the phases connected to L1 and L2. An incorrect connection could
damage the servo amplifier.
7. This is for the 400V. The 200V does not require a step-down transformer.
8. Do not reverse the diode’s direction. Connecting it backwards could cause the amplifier to malfunction that signals are not output, and emergency stop and other safety circuits are inoperable.
9. Make sure that the sum of current flowing to external relays does not exceed 80mA. If it exceeds 80mA, supply interface power from an external source.
10. Malfunction signal (ALM) is turned on during normal operation when no alarms have been triggered.
11. Create a sequence that cuts off the MC when a servo alarm occurs. Use the “Malfunction” output for the MR-J2S-A type, CP type or CL type.
