Checking Displays
•
When the power is turned on, one of the codes shown below will be displayed.
Normal (Base block)
Error (Alarm Display)
b b
0 2
Note
1. “Base block” means that the Servomotor is not receiving power.
Note
2. The alarm code (the number shown in the alarm display) changes depending on the contents of the
error.
•
If the display is normal (i.e., no errors), use it as a monitor mode speed display. Manually turn the
Servomotor shaft clockwise and counterclockwise, and check to be sure that it agrees with the posi-
tive and negative on the speed display. If it does not agree, then the encoder signal line may be wired
incorrectly.
