Installing the Inverter
36
+15 V open collector (or complementary) settings: Switch (JP1) – OC
Set JP1 switch to down position (OC: Open Collector) and connect the following
encoder cables to CN2 terminal block after checking the encoder signals: 15PE
(+15 V), GE, A+[PA], B+[PB]
Correctly connect the wires according to the encoder’s power specifications.
Otherwise, the encoder may be damaged.
Ensure that the encoder type is properly set before operating the inverter. Do
not change the encoder type settings while the inverter is operating. Doing so
may adversely affect the system and the inverter operation may stop with a
fault trip.
Note
•
The motor may operate incorrectly or vibrate if the rotor and the encoder’s
spindle are not connected correctly.
•
Use STP cables and connect the shielding to the PCB’s grounding screw.
•
Do not run encoder signal cables near inverter mains power cables.
Electronic interference may affect encoder output signals.
