Standard Wiring Diagram
Notes:
1. Do not reverse the diode’s direction. Connecting it backwards could cause the servo amplifier to malfunction that signals are not output, and emergency stop and other safety circuits are
inoperable.
2. Provide a 24VDC±10% 200mA power supply from an external source for the interface. 200mA is the value when all input/output signals are used. The current capacity can be stepped
down according to the number of input/output points in use.
3. EMG (emergency stop) contact (normally closed contact) must be installed. If it is not installed, operation will be impossible.
4. LSP and LSN contacts must be closed for normal operation. If they are not closed, the commands will not be accepted.
5. Signals with the same name are connected inside.
6. Malfunction signal (ALM) is turned on during normal operation when no alarms have been triggered.
7. For the motor with an electromagnetic brake. The electromagnetic brake terminals (B1, B2) do not have the polarity.
8. Connect the shield wire securely to the plate inside the connector (ground plate).
9. Always use a shielded multicore cable up to a maximum of 15m in a low noise environment. However, if the RS-232C communication is set up with a baud rate of more than
38400bps, keep the cable length to within 3m.
10. Refer to “MR-E-A/AG INSTRUCTION MANUAL” for details.
11. When using a 1-phase 230VAC power supply, connect the power supply to the L1 and L2 terminals. Do not connect anything to L3. The 1-phase 230VAC power supply is available only
for MR-E-70AG or smaller servo amplifiers.
12. Use the analog monitor/RS-232C branch cable (MR-E3CBL15-P) when connecting the analog monitor output 1 (MO1), analog monitor output 2 (MO2) and a personal computer.
Disconnect P and D when
connecting the optional
regeneration unit externally.
