Figure 4. Motor Connection
3. Connection of Equipment and Operation method
3.1 Necessary Equipment
・
Main Power Supply ( for VCC : DC Supply under 28V )
・
Sub Power Supply ( for 5V DC Supply )
・
Oscillator for CLK signal( Microcomputer or Function Generator )
・
Stepping Motor
3.2 Connection of stepping motor to Equipment
1. Connect the motor ( CN1 : OUT1A, OUT1B, OUT2A, OUT2B Terminal ).
2. Connect Main Power Supply between the Terminals of Vcc to GND. Please set any voltage
( 19V to 28V
＠
BD63715AEFV, other 4 are 8V to 28V ). Please keep the output to OFF.
3. Connect Main Power Supply between the Terminals of 5V to GND. Set 5V voltage. Please keep the output to OFF.
4. If input CLK Signal, MODE0 Signal, CW_CCW Signal, ENABLE Signal and MODE1 Signal via CN2, set SW6, SW3, SW5
and SW2 to OPEN.
Please set TEST Terminal to OPEN.
5. Connect Oscillator to CLK Terminal. Set Signal Level of Oscillator, Lo Level : under 0.6V, Hi Level : the range of 2.8V to
5.0 V. Set any frequency depending on drive speed.
6. Set ENABLE Terminal ( SW1 ), PS Terminal ( SW7 ) to Lo.
7. Turn on the DC Power Supply, and input CLK Signal (The motor w
on’t rotate yet).
8. Set PS Terminal (SW7), ENABLE Terminal ( SW1 ) to Hi ( The motor rotate ) .
9. If you can check the rotation of motor, please coordinate each setting condition ( VREF voltage, MTH voltage ) so that a
motor is driven optimally. ( Cf. P.8/15 ) .
