*1 1 to 50 of PA, PB, PC, and PD are used when writing data to
the servo amplifier RAM.
1001 to 1050 of PA, PB, PC, and PD are used when writing
data to E
2
PROM of the servo amplifier.
*2 The GOT cannot read or write data from/to consecutive
devices.
*3 Only reading is possible.
*4 Only reading is possible for DI0 to DI1.
Precautions for SP, OM, TMB, TMI, TMO, and TMD
devices
(1) For bit devices
Only writing is possible.
[Alternate] of a bit switch cannot be used.
Use [Set], [Reset], and [Momentary] of a bit
switch.
(2) For word devices
Only writing is possible.
Numerical input cannot be used.
When writing, use [Word Set] of a data set switch.
