Function
Remarks
1
positive input of a
differential amplifier.
See Appendix C.
2
Negative input of a
differential amplifier.

5
Analog input
This input is monitored by the main
µ
P. When |Vi|
< 5V, R1=470ohm should be inserted. When |Vi|>
5V, R1(Kohm)=2Vi-10 should be inserted. The
µ
P
always reads a range of +5V.

Current monitor
This analog output represents the actual current
in the motor. The scale (in A/V) is: Ip / 7.5
Ip - Rated peak current of amplifier.
