Panasonic A6 Motor & Driver Instruction 3.4 Inputs and outputs on connector X4 — Interface Circuit (Input)

Abstract

Here in this chapter is the wiring instruction of input/out connecting to the contacts of switches and relays, or open collector output transistors.

• Connect to contacts of switches and relays, or open collector output transistors.
• When you use contact inputs, use the switches and relays for micro current to avoid contact failure.
• Make the lower limit voltage of the power supply (12V to 24V) as 11.4V or more in order to secure the primary current for photocouplers.
• 
• 10 sysems: SI1 to SI10. For assign and function, refer to P.3-40 to P.3-45.

1. Line driver I/F (Permissible max, input frequency of command pulse input signal.: 500 kpulse/s)
   • This signal transmission method has better noise immunity. We recommend this to secure the signal transmission.
2. Open collector I/F (Permissible max. inout frequency of command pulse input signal.: 200 kpulse/s)
   • The method which uses an external control signal power supply (VDC)

     VDC	Specifications
     12V	820 Ω 1/2W
     24V	2 kΩ 1/2W
     (VDC - 1.5)/(R+220) = 10mA

   • Current regulating resistor (R) corresponding to VDC is required in this case.
   • Connect the specified resister as below.
   • (R) should be placed close to the driver for effective noise reduction.
3. Open collector I/F (Permissible max. input frequency of command pulse input signal.: 200 kpulse/s)
   • Connecting diagram when a current regulating resistor is not used with 24V power supply.
     
   • 1 system: Pl1. For function, refer to P.3-38, P.3-39.

Line driver I/F (Permissible max. input frequency of command pulse input signal.: 8 Mpulse/s)

• This signal transmission method has better noise immunity.
  We recommend this to secure the signal transmission when line driver I/F is used.
  
• 1 system: P12. For function, refer to P.3-38, P.3-39.

• It goes through 3 systems, AI1 to AI3.
• Max. permissible input voltage to each input is ±V.
  For input impedance of each input, refer to the right Fig.
• When you compose a simple command circuit using variable resistor (VR) and register R, connect as the right Fig. shows. When the variable range of each input iss made as -10V to + 10V, use VR with 2 kΩ, B-characteristics, 1/2 W or larger, R with 200 Ω, 1/2 W or larger.
• A/D converter resolution of each command input is as follows.
  (1) ADC1: 16-bit (AI1)
  (2) ADC2: 12-bit (AI2, AI3)
  
• For function, refer to P.3-46, P.3-47.
