(13) LS-Z pulse (displayed digits: unsigned seven digits)
The number of pulses in a homing counted since the home
position LS signal is turned off until the Z-phase of the
encoder of the servomotor is detected is displayed. The
indication is updated every time homing is performed.
Because the value is in the homing direction, no negative
sign is attached.

Displayed only if the Z-phase is enabled.
(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.
(Load inertia ratio) =
(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 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.
