Pin

Function

Remarks

1

positive input of a

differential amplifier.

See Appendix C.

2

Negative input of a

differential amplifier.

Circuit common

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.
