(
30k TO 55kW
)
13.4.2 Status display mode
The servo status during operation is shown on the 3-digit, 7-segment LED display. Press the "UP" or "DOWN"
button to change display data as desired.
When the required data is selected, the corresponding symbol is displayed. Press the "SET" button to display
that data.
The converter unit display section can show four items of data such as the effective load factor.

(b) Display definition
The 7-segment LED segments and CN1 connector pins correspond as shown below.
Lit: ON
Extinguished: OFF
Input signals
Output signals
CN1-7: Forced stop (EM1)
CN1-8:
Warning (WNG)
CN-2:
Trouble (ALM)
The LED segment corresponding to the pin is lit to indicate ON, and is extinguished to indicate OFF.
(3) Output signal forced output
You can force the output signal to be switched on/off, independently of the converter status.
This function is used for wiring check of output signal.
