Multi-function Compact Inverter 3G3MX2-V1 User’s Manual (I585-E1)
The position data storage at power shutoff function enables the inverter to store the data of the Current
Position Monitor (d030) into the EEPROM at power shutoff so that the data can be set in the Current
Position Monitor at the next power-on.
This allows you to use the origin position once established by the origin search function continuously
even after turning on the power supply again.
However, to use this function, observe the following precautions:
• To store the Current Position Monitor data at power shutoff, set the Position Store Selection at Power
Off (P081) to 01 (Store).
• The position data storage at power shutoff function stores the position data into the Position Data at
Power Off (P082) when the power supply is shut off. This data will be set in the Current Position Mon-
itor at the next power-on.
Although you can set data in the Position Data at Power Off (P082), the operation is ineffective
because it will be overwritten at the next power shutoff.
Because the Digital Operator of this inverter has a 4-digit display, you can monitor only the upper 4
digits.
To monitor a value over 4 digits, use the computer tool CX-Drive.
• If the motor rotates when the power supply is shut off, the inverter cannot recognize the rotation
amount, which causes position error.
Take measures to prevent motor rotation at power shutoff, for example, by using the brake.
If the motor rotated after power shutoff, perform origin search operation to establish the origin in
advance.
• Even if the brake is applied at power shutoff, the position error may occur due to backlash. Because
this positional error is accumulated, perform origin search once per several startups to eliminate it.
