24VDC Connection/Digital Input – Sizing of the power supply is based
on the number of input and output selections. Figure 6.18 shows the
typical connection of the digital input using the external power supply.
Analog Input – Velocity and Trim Reference. Connections for the
velocity and trim reference inputs can be for uni- or bi-directional
operation, using the internal drive
±
10VDC power supply (see Fig.6.19 ).
