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 "Optional data monitor data type
setting error" (warning code: 116) will occur with initialized communication to
servo amplifier and "0" will be stored 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 setting other than "0", the warning "Optional
data monitor data type setting error" (warning code: 116) will occur with
initialized communication to servo amplifier and "0" will be stored 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 Section 14.11 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.
