2. Installation and Wiring2-82-4 Precautions for Wiring to the Control Signal1) Separate the main circuit wiring (to terminals L1, L2, L3, L+1, L+2, L–, B, U, V, W) from the otherdrive wires and power wires.2) Use a 0.25 to 0.75mm² wire for wiring to the control circuit. The tightening torque must be 0.6Nm.3) Use a twisted pair wire or twisted pair shield wire for wiring the analog signals (as the setters and meter).(Fig. 2-6.) Connect the shield wire to the TB2 COM terminal of the VAT2000.The wire length must be 30m or less.4) The analog output is dedicated for metering only, such as the speed-meter and ammeter.It cannot be used for control signals such as the feedback control.5) The length of the sequence input/output contact wire must be 50m or less.6) The sequence input (digital I/Os), can be selected either sink logic or source logic method by theshort pin (W1). Refer to Table 5-2.7) Observe the precautions listed in "Table 5-2 Control input/output circuit".8) An example of the control circuit wiring is given in Fig. 2-6.9) The layout of the control circuit terminal block is shown in Fig. 2-7; functions are in Table 5-1.Terminals with the same terminal symbol are internally connected.10) After wiring, always check the wiring.
