9.10 Optional Data Monitor Function
9.10
Optional Data Monitor Function
This function is used to store the data (refer to following table) up to four points per axis to the buffer memory and monitor
them.
Data that can be set

: Possible,

: Not possible ("0" is stored.)
*1 The motor speed that took the average every 227 [ms].
Use the servo amplifiers of version compatible with the monitor of motor speed.
Always "0" if the monitor is executed for the servo amplifier which does not support this function.
*2 The data set to "Droop pulse monitor selection for controller display" of "Fully closed loop function selection 3 (PE10)" is monitored.
*3 It can be monitored when using the linear servo motors.
*4 It can be monitored when using the fully closed control.
*5 It can be monitored when using the synchronous encoder via servo amplifier.
Refer to each servo amplifier instruction manual for details of the data monitored.
