4. STARTUP
4 - 23
Status display Symbol Unit Description
Bus voltage Pn V The voltage of main circuit converter is displayed.
Internal temperature of
encoder
ETh °C Inside temperature of encoder detected by the encoder is displayed.
Settling time ST ms Settling time is displayed. When it exceeds 1000 ms, "1000" will be displayed.
Oscillation detection
frequency
oF Hz Frequency at the time of oscillation detection is displayed.
Number of tough drive
operations
Td times The number of tough drive functions activated is displayed.
Unit power consumption 1
(1 W unit)
PC1 W
Unit power consumption is displayed by increment of 1 W. Positive value indicate
power running, and negative value indicate regeneration. The values in excess of
±99999 can be counted. However, the counter shows only the lower five digits of
the actual value since the servo amplifier display is five digits.
Unit power consumption 2
(1 kW unit)
PC2 kW
Unit power consumption is displayed by increment of 1 kW. Positive value
indicate power running, and negative value indicate regeneration.
Unit total power consumption
1 (1 Wh unit)
TPC1 Wh
Unit total power consumption is displayed by increment of 1 Wh. Positive value is
cumulated during power running and negative value during regeneration. The
values in excess of ±99999 can be counted. However, the counter shows only
the lower five digits of the actual value since the servo amplifier display is five
digits.
Unit total power consumption
2 (100 kWh unit)
TPC2 100 kWh
Unit total power consumption is displayed by increment of 100 kWh. Positive
value is cumulated during power running and negative value during regeneration.
(4) Changing the status display screen
The status display item of the servo amplifier display shown at power-on can be changed by changing
[Pr. PC36] settings. The item displayed in the initial status changes with the control mode as follows.
Control mode Status display
