[Pr.91] to [Pr.94] Optional data monitor: Data type setting 1/2/3/4
Set the data type monitored in optional data monitor function.
*1 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 477 Axis monitor data)
*2 The name differs depending on the connected device.
• The monitor address of optional data monitor is registered to servo amplifier with initialized communication
after power supply ON or CPU module 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" will be 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 setting other than "0", the warning "Optional data monitor data type setting error" (warning
code: 0933H) will occur with initialized communication to servo amplifier and "0" will be 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 Optional Data Monitor Function 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.
