E17 Circuit Diagram
1.
Block diagram
The circuit diagram shown on page 10/16 consists of the following functions and connectors:
•
IC21 (Send motor drive)
•
Connector CN5 that provides an interface between E17 board and the send motor.
Figure A3.1.11 shows the related signals of the send motor.

Function
1)
Send motor rotaion and chopper control
Send motor drive signals are generated by the IEXSEED300 and output to send motor
via IC21 (motor drive IC) of this circuit.
Note: The built-in motor control circuit of IEXSEED300 consists of the following
blocks:
•
Setting of the excitation operation
•
Setting of the chopping operation
•
Setting of the chopping frequency
•
Setting of the motor forward
•
Setting of the motor excitation method (1-2/2-1 phase excitation)
a)
Send motor rotaion control
There are several cases of the rotation operation:
Forward rotation for feeding documents.
•
Case 1: Feeding document from hopper to the position where one line data
is read.
•
Case 2: Feeding document while reading.
•
Case 3: Feeding document after a page has been read.
b)
Send motor chopper control
The purpose of chopper control is to reduce the current to the motor by setting
the phase signal on and off intermittently when a time lapse exceeding a specific
time occurs without a phase update.
