Configure the origin search function settings as shown below based on the required operation.
• In the Origin Search Mode (P068), set the origin search mode to use.
• In the Origin Search Direction Selection (P069), set the direction in which to start the origin search
function according to your application.
• Set the Origin Search Mode 1 Frequency (P070) when the Origin Search Mode (P068) is set to 00
(Origin search mode 1), and set the Origin Search Mode 1 Frequency (P070) and Origin Search
Mode 2 Frequency (P071) when P068 is set to 01 (Origin search mode 2).
• Set any two of the Multi-function Input S1 to S7 Selection (C001 to C007) to 69 (ORL: Origin search
limit signal) and 70 (ORG: Origin search startup signal).
• The origin search function does not work when the Position Control Mode Selection (P075) is set to
01 (No limit).
Be sure to set the Position Control Mode Selection (P075) to 00 (Limit).
The current position preset function presets the current position to another position.
Use this function when the origin established by the origin search function is different from the actual
origin in the application.
• In the Preset Position Data (P083), set any position that you want to define as the origin of your appli-
cation. This value must be set as
×
1 multiplication pulses (equivalent the number of phase-A pulses).
Because the Digital Operator of this inverter has a 4-digit display, you can set only the upper 4 digits.
To set a value over 4 digits, use the computer tool CX-Drive.
• When the Multi-function Input S1 to S7 Selection (C001 to C007) is set to 91 (PSET: Preset position)
and that input terminal is turned ON, the Preset Position Data (P083) value is set in the Current Posi-
tion Monitor (d030).
• The current position preset function is enabled when the Pulse Train Input RP Selection (P003) is set
to 01 (Feedback pulse), independent of the Simple Position Control Selection (P012) setting.
• The current position preset function does not work when the Position Control Mode Selection (P075)
is set to 01 (No limit). Be sure to set the Position Control Mode Selection (P075) to 00 (Limit).
