Mechanical and Electrical Installation
In applications where the analog signal suffers severe interference, install filter
capacitor or ferrite magnetic core at the analog signal source.
Figure 3-16 Install filter capacitor or ferrite magnetic core
2) Wiring of DI terminals
Generally, select shielded cable no longer than 20 m. When active driving is adopted,
necessary filtering measures shall be taken to prevent the interference to the power
supply. It is recommended to use the contact control mode.
a. SINK wiring
Figure 3-17 Wiring in SINK mode
This is the most commonly used wiring mode. To apply external power supply, remove
jumpers between +24 V and OP and between COM and CME, and connect the positive
pole of external power supply to OP and negative pole to CME.
In such wiring mode, the DI terminals of different AC drives cannot be connected in
parallel. Otherwise, DI mal-function may result. If parallel connection (different AC
drives) is required, connect a diode in series at the DI and the diode needs to satisfy
the requirement: IF > 10 mA, UF < 1 V.
