Notes:
1. Do not reverse the diode’s direction. Connecting it backwards could cause the servo amplifier to malfunction such 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. Note that the current capacity can be
stepped down according to the number of input/output points in use. Refer to “MR-E-MA/AG-KH003 INSTRUCTION MANUAL” for details.
3. Always turn on the emergency stop (EMG) signal (normally closed contact) before starting the operation. If not, the operation will not start.
4. Always turn on the forward/reverse stroke end (LSP/LSN) signals (normally closed contact) before starting the operation. If not, the commands will not be accepted.
5. Signals with the same name are connected internally.
6. The malfunction (ALM) signal (normally closed contact) is conducted to SG in normal alarm-free condition.
7. This is for the motor with an electromagnetic brake. The electromagnetic brake terminals (B1, B2) do not have polarity.
8. Connect the shield wire securely to the plate inside the connector (ground plate).
9. This connection is not necessary for QD75D of the positioning unit. Note that the connection between LG and the control common terminal is recommended to increase noise resistance
depending on the positioning unit being used.
10. A shielded multicore cable must be used. The cable length up to 15m is possible 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 within 3m.
11. The signals shown apply when using a two-wire type encoder cable. Encoder cable 30m or longer is four-wire type. Refer to “MR-E-MA/AG-KH003 INSTRUCTION MANUAL” for details.
12. When using a power supply, 1-phase 230VAC, 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 the MR-E-70A-KH003 or smaller servo amplifier.
13. 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 at the
same time.
14. Connect P and D when using the built-in regenerative resistor.
15. Disconnect P and D when connecting the optional regeneration unit externally.
16. This length applies to the command pulse train input in the differential line driver system. For the open collector system, the length should be 2m or shorter.
