15. SERVO AMPLIFIER CONNECTION
15.6 Device Range that Can Be Set
(e) Alarm
(f) External I/O signal
(g) Forced output of signal pin (for test operation)
(3) MELSERVO-J2M-*DU
*1 Use PRM0 to PRM84 when writing parameters to the servo
amplifier RAM.
PRM1000 to PRM1084 are used when writing parameters to
E
2
PROM of the servo amplifier.
*2 The GOT cannot read or write data from/to consecutive
devices.
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.
