YASKAWA JUNMA SERIES User Manual

19
Applicable line driver: SN75174 or MC3487 (Manufactured by Texas Instruments or equivalent)
Set the R1 through R3 current limit resistors so that input current (i) will fall within the following range.
Input current (i) = 7 mA to 15 mA
*
:
Twisted-pair wires
Examples:
•
When Vcc is +24 V: R1 through R3 = 2.2 kΩ
•
When Vcc is +12 V: R1 through R3 = 1 kΩ
•
When Vcc is +5 V: R1 through R3 = 180 Ω
Note: The following signal logic applies for
an open-collector output.
Tr1 to Tr3 ON Equivalent to high level input
Equivalent to low level inputTr1 to Tr3 OFF
