Wiring Precautions
 Always turn off power before connecting or disconnecting the equipment.
 Do not turn on the AC power until all installation work is complete. There is no ON/OFF switch on the
unit itself.
 Do not drop the equipment or subject it to strong impact.
 Be sure to attach the acrylic cover provided on the power supply connector board before use.
 Tighten the terminal screws on the connector boards to the following torques:
Connector board Connector board screw

Power supply
connector board 1.4 Nm
Connector 0.25 Nm
The crimp terminals conforming to the equipment connector boards are as shown in the following table.
Connector board Crimp terminal

connector board Up to 9.0 mm O type: 1.25-4, 2-4 or Y type: 1.25-4, 2-4
Connector Up to 2.0 mm Flat type 1.25-AF2.3B
Keep cables connected to the unit as far away as possible from sources of noise such as power lines or
control interfaces.
 The conduit should house exclusively cables connected to the equipment itself. Avoid joint use with
other lines in the conduit.
 Always ground the equipment. Use Type D single grounding. Do not share a ground with the power
supply system.
 Use shielded cable for the external control input/output connections, and connect the shield wire to
the F.G. Terminal on the power supply connector board.

 The DBX-001 power supply box is required when connecting the OPT-564 to the TMHFB, TMOFB,
and TMOS optical transmission torque transducers.
 Always use the cable provided with the torque meter to connect the equipment to the torque
transducer. To avoid increased sensitivity to external noise and loss of accuracy, do not use a
connector board to extend the cable. If the standard cable included is too short, contact a
MinebeaMitsumi sales office or dealer.

External Control Input/Output Connection
The external control input/output connectors on the rear panel can be used to control functions externally.
External control input is performed by shorting the corresponding inputs to COM using contacts or an
open collector after wiring the connectors.
The external control output forms the open collector output.
(Open collector rating: VCE = 35 V DC, IC = 40 mA DC max.)

No. Signal Operation
1 A/Z (pulse)
This operation activates the auto-zero function to reset the reading to
[0] if the value displayed on the torque display is 10 % or less of the
maximum value. [A/Z] also lights up on the status display. (The
operation is the same as for pressing the key in Section 3-2.) For
further details of the operation, refer to Section 5-4.
2 A/Z OFF (pulse)
Operates the auto-zero cancel function only when the auto-zero
function is operating, setting the torque reading to the current torque
and clearing [A/Z] on the status display.
3 LOCK (level) All key inputs are locked (prohibited) while this signal is input, and
[LOCK] lights up on the status display.
4 Rotation POL.
(level)
This signal is enabled when [Measure with one rotation detector,
detect rotation direction using external input signal] is set for F-24.
The rotation direction is reversed while this signal is input.
5 COM The common for input/output terminals (terminals 1 to 4 and 6 to 9).
6 ERROR IN (pulse) Cancels the error when an error occurs in the OPT-564.
8 SEL1 (level) The calibration number can be selected using this signal input when
F59 = 0.
9 SEL2 (level)
 External control input signals may be detected using pulse input or level input.
 The A/Z, A/Z OFF, and ERROR IN inputs are operated after shorting for at least approximately 100 ms
(once only).
 The LOCK, Rotation POL, SEL1, and SEL2 inputs are enabled during input after shorting for at least
approximately 100 ms.
 If F-26 is set to 1, the A/Z function will be retained even when the OPT-564 power is turned off and
then back on.
