3.6 Interface
■
Open-collector type
• Interface
*1 A photocoupler is used as the pulse train input interface. Therefore this circuit may not operate properly due to reduction in current if a
resistor is connected to the pulse train signal line.
• Input pulse condition
Encoder output pulse DO-2
■
Differential line driver type
• Interface
Maximum output current: 35 mA
