Multi-function Compact Inverter 3G3MX2-EV2 User’s Manual (I666-E1)
When the power supply is turned on, the inverter clears the current position data to zero before startup.
Therefore, you need to establish the origin for position control before performing simple position con-
trol.
This section describes the current position clear and origin search functions to establish this origin.
It also describes the current position preset and position data storage at power shutoff functions associ-
ated with the origin search function.
When the Multi-function Input 1 to 7 Selection (C001 to C007) is set to 47 (PCLR: Current position
clear) and that input terminal is turned ON, the current position data is cleared. The position at that time
is set as the origin.
• Move to the position to set the origin and turn ON the current position clear signal to establish the ori-
gin.
• The current position clear signal is enabled when the Pulse Train Input EA Selection (P003) is set to
01 (Feedback pulse), independent of the Simple Position Control Selection (P012).
