Note: 1. To prevent an electric shock, fit the supplied earth terminal (E) to the servo amplifier and always

connect it to the earth (E) of the control box. (Refer to section 3.9.)

2. Connect the diode in the correct direction. If it is connected reversely, the servo amplifier will be

faulty and will not output signals, disabling the forced stop and other protective circuits.

3. The forced stop switch must be installed.
4. CN1A and CN1B have the same shape. Wrong connection of the connectors will lead to a fault.

5. When starting operation, always connect the forward/reverse rotation stroke end signal (LSN/LSP)

with SG. (Normally closed contacts)

6. Trouble (ALM) is connected with COM in normal alarm-free condition.

7. The pins with the same signal name are connected in the servo amplifier.
8. TLA can be used by setting any of parameters No. 43 to 48 to make TL available.

9. Use MRZJW3-SETUP61E or later.
