16. SERVO AMPLIFIER CONNECTION
16.6 Device Range that Can Be Set
(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.
The following shows correspondences between virtual
devices for servo amplifier and data of the servo
amplifier used with the GOT.
(a) Servo amplifier request
(b) Operation mode selection
(c) Instruction demand (for test operation)
(d) Basic parameter/expansion parameter
