Operation
4-7 Operating Functions
4-7-1 Position Control
■ Functions
• Perform position control using the pulse train input from CN1-1,2 for CW and CN1-3,4 for CCW.
• The Servomotor rotates using the value of the pulse train input multiplied by the electronic gear
ratio (Pn202, Pn203).
Note If function switch 6 is OFF to enable the function switch settings, this parameter is ignored and
the setting on function switches 4 and 5 (resolution setting) is used.
■ Settings
● Using Function Switches (Function Switch 6 Turned OFF)
● Using Parameters (Function Switch 6 Turned ON)
Function switch Explanation
Command pulse input setting (switch 3) Set to match the Controller command pulse type.
Resolution setting (switches 4 and 5) Set to 500, 1,000, 5,000, or 10,000.
