Multi-function Output Terminal and Relay Setting Details
Code Description
OU.31
Relay1
Set relay (Relay 1) output options.
OU.33 Q1
Define
Select terminal (Q1) output options. Q1 is an open collector transistor output.
OU.41 DO
Status
When terminal Q1 and/or Relay1 outputs are set for frequency related functions FDT-1
through FDT-4, use parameters OU.57 FDT (Frequency), OU.58 (FDT Band) settings for
the detection criteria.
Setting Function
0 None No output signal.
1 FDT-1 FDT-1 setting compares the reference frequency to
the actual output (operating) frequency. Relay1 (or
Q1) closes when the difference between the two
frequencies is within ½ the FDT Band, OU.58.
