POINT
(1) The monitor address of optional data monitor is registered to servo amplifier with
initialized communication after power supply ON or PLC CPU reset.
(2) Set the data type of "used point: 2 words" in "
Pr.91
Optional data monitor: Data
type setting 1
" or "
Pr.93
Optional data monitor: Data type setting 3
". If it is set in
"
Pr.92
Optional data monitor: Data type setting 2
" or "
Pr.94
Optional data monitor: Data
type setting 4
", the warning (warning code: 116) will occur with initialized
communication to servo amplifier, and "0" is set in
Md.109
to
Md.112
.
(3) Set "0" in "
Pr.92
Optional data monitor: Data type setting 2
" when the data type of
"used point: 2 words" is set in "
Pr.91
Optional data monitor: Data type setting 1
", and
set "0" in "
Pr.94
Optional data monitor: Data type setting 4
" when the data type of
"used point: 2 words" is set in "
Pr.93
Optional data monitor: Data type setting 3
".
When other than "0" is set, the warning (warning code: 116) will occur with
initialized communication to servo amplifier, and "0" is set in
Md.109
to
Md.112
.
(4) When the data type of "used point: 2 words" is set, the monitor data of low-order
is "
Md.109
Regenerative load ratio/Optional data monitor output 1
" or "
Md.111
Peak
torque ratio/Optional data monitor output 3
".
(5) Refer to this Section "[1] Data that can be set" for the data type that can be
monitored on each servo amplifier. When the data type that cannot be
monitored is set, "0" is stored to the monitor output.
