⑥ Current sensor
To detect motor current, pass the V-phase motor wire through
the sensor in the direction from the power supply side to
motor side as shown by the arrow. Make sure that the
direction of the wire matches with the arrow on the top of the
current sensor. The number of times to pass the wire through
the sensor depends on the motor capacity and voltage. Refer to
the following table for the specified number.
The figure on the left shows the case where the number of
times to pass the wire through the sensor is two (2).
(Note) Refer to the connection diagrams on pages 10 and 11 for
the current sensor wiring and be sure to pass through the motor
wire of the correct phase which is connected with the voltage
input terminal V[2] of the TSM4000. If the wire of the other
phase is connected, or the wire is passed through in the opposite
direction, the electric power cannot be detected properly. This
wiring is unrelated to the positive/reverse phase of the power
supply or of the forward/reverse rotation switching of the motor.

■ Connecting the sensor cable to the main unit
Connect the sensor cable TSM4-S01 included in the package properly to the current
sensor and Shock Monitor main unit respectively. If the cable length is insufficient,
longer cables are optionally available. Refer to page 4 for the model number of the
sensor cable and contact TEM for ordering.
