Chapter 10 Application of Special Functions
Besides the common functions, the MV820 drive also provides some special functions to lower the cost and improve the
convenience for customers.
10.1 Closed-loop application
Hardware wiring
(1) OC wiring
When the encoder’s ABZ signal has only one cable for output, the OC wiring is adopted, as shown in Fig. 10-1.
Fig. 10-1 OC wiring
(2) Differential wiring
When the encoder’s ABZ signal is differential output, the differential wiring can be adopted, as shown in Fig. 10-2. Note:
In this case, OC wiring can also be adopted, and at the time, the encoder’s ABZ- is disconnected (ABZ+ connected to the
ABZ+ of the PG card) or the encoder’s ABZ+ is disconnected (ABZ- connected to the ABZ+ of the PG card).
