Check if the upper unit transmits the communication command within the setting
time for Pr. 09-03.
Verify the wiring and grounding of the communication circuit. It is recommended
to separate the communication circuit from the main circuit, or wire in 90 degree
for effective anti-interference performance.
Check if the setting for Pr.09-02 is the same as the setting for the upper unit.
Check the cable and replace it if necessary.

parameters (the error displays on the upper right corner of the copy page). If you
cannot clear the error, please contact Delta.
