Analog Input Signals

· Master Analog Input Selection (n043, Analog Input Sel)
To input the master frequency reference from the control circuit terminal, use
terminal FV (0 to 10V) or terminal FI (4 to 20mA), by setting parameter n043.
LED Setting
0 FV=MSTR FI=AUX
1 FV=AUX FI=MSTR
· Auxiliary Analog Input Selection (n044, Terminal FI Sel)
From the factory, terminal FI is set to accept a 4-20mA signal. To change the
control circuit terminal FI input level from current to voltage, set parameter
n044 according to the table below, and be sure to cut the "J1" jumper on the
control PCB. The J1 jumper is located near terminal FI on the control PCB.

* To set parameter n044 to "0", cut jumper J1 on the inverter control PCB board.
· Frequency Reference Retention (n045, MOP Ref Memory)
Effective when UP/DOWN or Sample/Hold commands are selected for multi-
function contact inputs. To retain the held frequency reference at power OFF,
set parameter n045 to"Memorize Fref". When n045="Memorize Fref", the last
sampled/held reference will be memorized during power down. When power is
re-applied, a run command will run the inverter at this previous speed. When
n045="Not Memorized", the last sampled/held frequency will be lost at power
down. Upon power-up, a new reference will need to be sampled.
LED Setting LCD Setting
0 Memorize Fref Held frequency retained in frequency reference 1 - n024 (factory default)
1 Not Memorized
· Operation Method for Frequency Reference Loss Detection (n046, Ref
Loss Detect)
Selects the frequency reference if the frequency reference from the con-
trol circuit terminal decreases rapidly (lost signal).
LED Setting
0 Not Detected
1 RUN @ n047 Fref Detection enabled, continue to run at n047 value × previous reference.
If the frequency reference decreases by 90% within 400ms (when
detection is enabled), operation continues at reference equal to the n047
value × previous reference.
