Example
Connection
*1. Y002 (pulse output destination) cannot be specified when the 14-point or 24-point type FX3G PLC is
connected.
*2. Devices related to Y003 (pulse output destination) are only valid if two FX
3U-2HSY-ADP adapters are
connected to the FX
3U PLC.
*3. 32 bits are used for the maximum speed setting device and the zero return speed setting device.
*4. Set this item using the PC parameter settings (positioning) of GX Developer (Ver.8.23Z or later) with
an FX
3U/FX3UC PLC Ver.2.20 or later or FX3G PLC. The settings data set by the parameter setting will
be stored in the corresponding device.
*5. To accelerate or decelerate the operation using the variable speed pulse output (PLSV) instruction
with an FX
3U/FX3UC PLC Ver.2.20 or later or an FX3G PLC, it is necessary to set this item.
If the operation is not accelerated or decelerated, or if an FX
3UC PLC below Ver.2.20 is used, the
PLSV instruction will not use this item even if it is set.
*6. The ZRN instruction will not use any zero return direction setting devices. Using the program, adjust
the rotation direction output to the zero return direction.
*7. This item can be set using an FX
3U/FX3UC PLC Ver.2.20 or later or an FX3G PLC.
*8. This item can be set using an FX
3U/FX3UC PLC Ver.1.30 or later.
The user interrupt input command, however, can only be set using an FX
3U/FX3UC PLC Ver.2.20 or
later.
*9. Use this function only if immediate stop is absolutely needed to avoid danger.
*10. Only available for FX
3U and FX3UC PLCs.
