(14) Load inertia ratio (displayed digits: unsigned four digits)
The load inertia ratio recognized by the servo amplifier without relations to parameter PA1_13
(tuning mode selection) is displayed. The value is displayed in a multiple (in 0.1 increments) to the
inertia of the servomotor itself.
The displaying range is from 0.0 to 300.0 times.

(15) DC link voltage (max.) (displayed digits: unsigned three digits)
The DC link voltage (max.) of the servo amplifier at every two seconds is displayed.
The displaying range is from 0 [V] to 500 [V].

If the DC link voltage (max.) exceeds 390 [V] during operation, an external regenerative
resistor is necessary. "HV" (overvoltage) is detected at 420 [V].
"LV" (under-voltage) is detected at 200 [V].
