Q9: What is the connection mode between PLC and servo?
1. NPN low-level output PLC: Y0 pulse connects P-, Y1 direction connects D-, +24V connects P+24,
D+24. (Xinje PLC as an example)
PNP high-level output PLC: Q0.0 pulse connects P+24, Q0.2 direction connects D+24, 0V connects P-,
D-. (Siemens PLC as an example) as follows:
Q10: What is the external connection method and parameter setting of regenerative resistance?
There are P+, D, C terminals on the servo interface. There are short connectors between P+ and C
(using built-in resistor). When the built-in resistor specifications are insufficient, the external resistor
should be replaced. The specifications of the external regenerative resistor please refer to chapter 1.4.1.
(1) P+, D, C interface model: Remove the short joint between P+, D, and connect the external
regenerative resistance to P+, C.
(2) P+, PB interface model: connect external regenerative resistance to P+, PB.
(3) Version number parameter U2-07 < 3700, set P0-24 = 1, P0-25 = power value, P0-26 = resistance
value.
(4) Version number parameter U2-07 ≥ 3700, P0-24 need not be set, P0-25 = power value, P0-26 =
resistance value.
Note: Before 3700 version, P0-24 should be set. Value 0 is for built-in resistance and value 1 is for
external resistance.
Q11: The service life of tank chain?
The bending resistance is 5 million times and the bending radius is 50 mm.
Q12: How to connect bus control BD board and JA-NE-L?
A-A1, B-B1, SG-SG when one axis running; the PLC BD board and the terminal resistor of the last
JA-NE-L board of electrical connection should be ON when multi-axis running; and the terminal
resistance of JA-NE-L board in the middle should be OFF.
