9-2. Preset Data (Output Data: Master → Slave)
The master can change the position data to any desired value by performing the preset function using Output Data.
The changed position data is stored in the converter's non-volatile memory. Therefore, there is no need to do the
preset function each time the power is turned on.

*1: The PRESET1/2 signal should be set to "0" if the position data is the same as the preset data. Although the
position data is changed when the PRESET1/2 signal changes from "0" to "1", the position data received by the
master remains the same as the preset data while the PRESET1/2 signal is "1". When the PRESET1/2 signal
changes to "0", the position data at that point can be read.
(When PRESET1/2 signal is changed to 1 by the PLC pulse instruction, "1" of the PRESET1/2 signal might not
be sent because of the relation between PLC scan time and Output Data update time of the PROFIBUS-DP
communication.)
*2: When the PRESET1/2 signal changes from "1" to "0", the converter cannot receive another PRESET1/2 signal
for a period of 100 ms.
NOTE
The preset function is disabled when a "sensor error" (SE) occurs.
