Panasonic AAD03011 - Wiring Precautions; Precautions on Wiring

䂓 Precautions on Wiring
1. Use shielded wires for all control signal wires and keep them away
more than 20cm from power lines and strong electric circuits.
2. The wiring length of the control signal wire is 30m or less.
3. The control circuit's input signal is a minute signal, so use two minute
signal contacts in parallel or use a twin contact to prevent contact
faults when inputting the contact.
4. No-voltage contact signal or open-collector signal should be used with
control terminals No. 1 to 7.
(If a voltage is applied across these terminals, the inverter may be damaged.)
䋪㩷Input circuit specifications are shown in Fig. 1.
Take special care to avoid loop or leakage current.

5. Precautions on encoder (Refer to Fig.2 and 3)
Note1) NPN open-collector output is used with ouput signal
(Phase A, Phase B) of the encoder.
Use the transistor that meets the specifications below.
䊶 Max. rated voltage : 30VDC or more
䊶 Rated current : 20mA or more
Note 2) Power supply of the encoder should be 12 V DC -10%/ ˇ20%.
Note 3) Consumption current of the encoder should be 50mA or less.
