2-3 Wiring „ Functions of the Control Circuit Terminals 2 Design 2-26 Terminal function Terminal Symbol Terminal name Function and connecting method Wire size Contact input (for switching function) S1 S2 S3 S4 S5 S6 Multi-function input Select functions and allocate them to terminals S1 to S6. (The figure below illustrates the wiring of the sink logic.) SC S6 S5 S4 S3 S2 S1 Shield wire of 0.14 to 0.75 mm2 Recom- mended wire size: 0.75 mm2 Power supply SC Input common Input signal common PSC Input power supply If the multi-function input terminal is set as the sink logic, the PSC terminal acts as an external power supply input terminal.
If the multi-function input terminal is set as the source logic, the PSC terminal acts as an internal power supply output terminal. External analog frequency reference FS Frequency reference power supply output •External voltage directive is 0 to 9.8 V. (Nominal input: 10 V) FS FV FI FC FS FV FI FC + – Variable resistor 0 to 9.8 V DC (1/2 W min.) (Nominal input: 10 V) 1 to 2 kΩ Input impedance 10 kΩ FS FV FI FC + – 4 to 19.6 mA DC (Nominal input: 20 mA) Input impedance 250 Ω Note: When the multi-function input terminal has no allocation of [16: AT], the frequency of total voltage and current directive values will be output.
When selecting and using either the voltage or current, be sure to allocate [16: AT] to the multi-function input terminal. FV Frequency reference input (Voltage directive) FI Frequency reference input (Current directive) FC Frequency reference common Monitor output AM Multi-function analog output • Choose from frequency or output current.
