PLC FX5U is a new type of small size PLC from Mitsubishi. It is integrated with many high level functions such as Analog In/Out, RS422/485, Ethernet… and it also supports up to 4-axis control pulse output.
Today plc247.com will guide you to use PLC FX5U to control Yaskawa Sigma 7 Series (similar Sigma V) motors in the simplest and easiest way to understand.
Mitsubishi FX5U & Yaskawa Sigma 7 “Wiring Diagram”
+ Use resistor R = 2K2Ω to reduce voltage: 24 VDC to 5 VDC
I/O Address Table
- Input
+ X0: Origin Sensor
+ X1: CW Limit Sensor
+ X2: CCW Limit Sensor
- Output
+ Y0: Pulse Output
+ Y4: Direction Output
+ Y5: Servo ON/OFF
Yaskawa Sigma 7 Parameters Configuration
Note: You can use Sigma Win software (download below the article) or install it with the button on the driver
For Driver Yaskawa Sigma 7 we need to configure the following basic parameters
+ Pn200.0: Reference Pulse Form
plc247.com uses 1 pulse control mode (Pulse + Direction)
>>> Select “0: Sign + Pulse, positive logic”
+ Pn200.3: Filter Selection
>>> Select “1: Uses reference input filter for open collector signal (to 200kpps)”
+ Pn20E + Pn210 + Pn212
“Three parameter is used to set the number of pulses for 1 revolution of the motor”
In this Project use “Ball screw leed = 5mm” & “Control 1PLS = 10um”
>>> Pn20E = 16,777,216
Pn210 = 500
+ Pn000.1: Control Method Selection
Mitsubishi FX5U Pulse Output Configuration
Mitsubishi FX5U Pulse Output Instruction
- Zero Return Instruction
- Absolute Pulse Output Instruction
- Increment Pulse Output Instruction

FX5U Pulse Output Configuration (on GX-Works3 Software)
+ Pulse Train Output Setting
In Project using Axis 1
+ Input Respose Time Setting
Because we use Input X0 as the original sensor, we need to set a fast response rate for X0.

+ Servo ON/OFF & Return Origin Control
+ Axis Jog Process
+ FX5U Position Control

Why this 2k ohm resistor is used with servo. Can this servo run without this resistor.
Reduce 24VDC > 5VDC
