 Input terminal polarity setting
The polarity of input terminals is set by the corresponding bits of D1799. bit #=ON sets the input
terminal as NO contact while OFF sets the input terminal as the NC contact. For example, to set
MPGA0/MPGB0 as NO contacts, users have to set ON b1 and b2 of D1799, i.e. specify D1799=6.

9.2.1.3 Setting an Input/Output Pulse Type
When Virtual Master is applied or the input pulses for Master are from Y axis of PM, settings of D1864
(MPG pulse input type) and D1816/D1896/D1976 (pulse output type) should match with each other, i.e.
if the source of Master is set as single phase (P/D), the output pulse type of Y axis should be single
phase as well. For wirings, simply connect MPGA0 (A0+, A0-) with Y axis output terminals (FP1+, FP1-)
and the setting is completed.
