MR-J2S-MCL (1) type
Notes:
1. Do not reverse the diode’s direction. Connecting it backwards could cause the amplifier to malfunction so that signals are not output, and emergency stop and other safety circuits are
inoperable.
2. 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.
3. LSP and LSN contacts must be closed for normal operation. If they are not closed, command will not be accepted.
4. Signals with the same name are connected inside.
5. CN1A, CN1B, CN2 and CN3 are all the same shape. Connecting them wrong can cause damage.
6. Malfunction signal (ALM) is turned on during normal operation when no alarms have been triggered.
7. If using the override (VC), make the override selection (OVR) device available.
8. If using the analog torque limit (TLA), make the external torque limit selection (TL) device available.
9. Connect the shield wire securely to the plate inside the connector (ground plate).
10. Always connect the servo amplifier protection ground (PE) (for preventing shocks) to the control box’s protection ground (PE).
