Chapter 6 Control Terminals MS300 6-1 Control Terminal Specifications Control Terminal Distribution Diagram Control Terminal Location Diagram Figure 6-6 Figure 6-7 Wiring precautions: 1. The factory default is +24 V/S1/S2 short-circuited by jumper, as shown in Area 1 in Figure 6-6. Refer to Figure 4-2 in Chapter 4 WIRING for details. 2. Use the +24V power supply of the safety function (as shown in Area 2 in Figure 6-7) for STO only. Do NOT use it for other purposes. 3. The RELAY terminal uses the PCB terminal block (as shown in Area 3 in Figure 6-6): Tighten the wiring with a 3.5 mm width and 0.6 mm thickness slotted screwdriver.
The ideal length of stripped wire at the connection side is 6–7 mm. When wiring bare wires, ensure that they are perfectly arranged to go through the wiring holes. 4. The Control terminal uses the push-in spring terminal block (as shown in Area 4 in Figure 6-6): Tighten the wiring with a 2.5 mm width and 0.4 mm thickness slotted screwdriver. The ideal length of stripped wire at the connection side is 9 mm. When wiring bare wires, ensure that they are perfectly arranged to go through the wiring holes.
