To prevent an electric shock, always connect the protective earth (PE) terminal of the servo amplifier to the protective earth of the control box.
Do not reverse the diode's direction. Connecting it backwards could cause the amp to malfunction so that signals are not output and emergency stop and other safety circuits are inoperable.
The emergency stop switch must be installed.
When using a regenerative brake resistor in combination with an amplifier in the power range of 350 A or less, always remove the lead from across the terminals D and P. When using an external brake unit or a
regenerative brake resistor in combination with amplifiers in the power range of 500 A or higher, disconnect the cable connections to the internal brake resistor. For further details please refer to the MR-J2S manual.
CN1A, CN1B, CN2 and CN3 have the same shape. Wrong connection of the connectors will lead to a fault.
Make sure that the sum of current flowing to external relays does not exceed 80 mA. If it exceeds 80 mA, supply interface power from an external source.
When starting operation, always switch on the external emergency stop signal (EMG) and forward/reverse rotation stroke end signal (LSN/LSP) (normally closed contacts).
The pins with the same signal name are connected in the servo amplifier.
The trouble (ALM) signal is on when there is no alarm, i.e. in the normal state. When the signal is switched off (at occurence of an alarm), the output of the controller should be stopped by the sequence program.

Only for motors with electomagnetic brake.

TLA can be used by setting any of parameters No. 43 to 48 to make TL available.
