NOTES:
•
0L and 0S common ground are equipotential and maximum permitted voltage against Power Earth
(PE) is 50V.
•
Maximum permitted voltage for 0V, 0V_I/O against Power Earth (PE) is 100V.
•
Do not use +24V (pin 2 of J8) to directly engage motor brake.
•
Single ended PNP connection for analog references is to connect negative pins
(pin 2-4-6 of J9)) to
0S ground (pin 8 of J9) and to connect signal to positive pins (pin1-3-5 of J9); this connection type is
usefull if the external controller device has not differential analog output, but ±10V single ended only,
and if this analog input is used as digital input.
•
Keep I/O cables far from supply and feedback cables.
•
To ensure a correct electric wiring, and for electric safety, strip the wire up to 6-8mm, or use an
appropriate cap.
•
For frequency main reference input and analog input, it’s mandatory to use shielded cable.
