These two output pairs are differential TTL incremental position signals generated by the Resolver feedback electronics. These outputs are quadrature encoded to emulate an optical encoder. The resolution of these signals, i.e. the emulated line count, is set by the EncOut parameter. These outputs are buffered by 26LS31 type RS-422 compatible line drivers. Maximum recommended load current is ± 20 mA, which corresponds to a minimum line-to-line load resistance of 100 Ω. This drive capacity corresponds to ten RS-422 compatible inputs such as the PC830 encoder inputs. These outputs are indefinitely short circuit proof to I/O RTN.
These two terminals function as a differential
TTL marker pulse. The output pulse occurs once per motor shaft revolution starting at resolver position = 0 and its width is approximately one quadrature encoder width. This output comes from an 26LS31 type RS-422 compatible line driver. Maximum recommended load current is ± 20 mA, which corresponds to a minimum line-to-line load resistance of 100 Ω. This drive capacity corresponds to ten RS-422 compatible inputs such as the PC830 encoder inputs. This output is indefinitely short circuit proof to I/O RTN.
These two connections provide
an auxiliary power supply for the user. This output is 5 Vdc ± 5% and is short circuit protected at 1 A nominal. The maximum load limit for all connections to this supply is 250 mA. The +5 VDC RTN (J2-15) is connected to I/O RTN (J2-3, J2-7, J2-16, J2-30).
