List of parameters and data
The parameters and data used in the optional data monitor function is shown below.
■Expansion parameter
n: Axis No. - 1
Setting item
[Pr.91] Optional data monitor: Data type setting 1
[Pr.92] Optional data monitor: Data type setting 2
[Pr.93] Optional data monitor: Data type setting 3
[Pr.94] Optional data monitor: Data type setting 4
• The monitor address of optional data monitor is registered to servo amplifier with initialized communication
after the power supply is turned ON or the CPU module is reset.
• 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: 0933H) will occur with initialized communication to servo amplifier, and "0" is set in
[Md.109] to [Md.112].
• 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 "Optional data monitor data type setting error" (warning
code: 0933H) will occur with initialized communication to servo amplifier, and "0" is set in [Md.109] to
[Md.112].
• 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".
• Refer to Page 340 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.
■Axis monitor data
n: Axis No. - 1
Storage item
[Md.109] Regenerative load ratio/Optional data
monitor output 1
[Md.110] Effective load torque/Optional data
monitor output 2
[Md.111] Peak torque ratio/Optional data monitor
output 3
[Md.112] Optional data monitor output 4
When the communication interrupted by the servo amplifier's power supply OFF or disconnection of
communication cable with servo amplifiers during optional data monitor, "0" is stored in [Md.109] to [Md.112].
Setting details/setting value
• Set the data type monitored in optional data monitor function every data type
setting. (Page 340 Data that can be set)
• When "0: No setting" is set, the stored value of "[Md.109] Regenerative load
ratio/Optional data monitor output 1" to "[Md.112] Optional data monitor output 4"
is different every data type setting 1 to 4. (Page 341 Axis monitor data)
Storage details/storage value
• The content set in "[Pr.91] Optional data monitor: Data type setting 1" is stored at
optional data monitor data type setting.
• The regenerative load ratio is stored when nothing is set.
• The content set in "[Pr.92] Optional data monitor: Data type setting 2" is stored at
optional data monitor data type setting.
• The effective load ratio is stored when nothing is set.
• The content set in "[Pr.93] Optional data monitor: Data type setting 3" is stored at
optional data monitor data type setting.
• The peak torque ratio is stored when nothing is set.
• The content set in "[Pr.94] Optional data monitor: Data type setting 4" is stored at
optional data monitor data type setting.
• "0" is stored when nothing is set.
