Commercial To lnverter When PU-CM is closed, reference increases and preparation for

inverter operation is made. When set to OFF after a fixed time,
inverter will operate. (Used for open transfer Line-lnverter-Line; also
used with terminal

for transfer.)

Output Starter

When providing an output starter, its auxiliary contact (normally

Interlock

closed) must be between IL-CM (closed). When the starter
up, the auxiliary contact must open (IL-CM open) permitting inverter
operation. IL-CM On interrupts inverter operation; IL-CM Off
continues inverter operation. Used with terminal

for transfer.

Open Collector Comm. Common terminal for output of open collectors.

lnverter In Operation

Transistor turns ON between RUN-CME at start frequency and
above. Transistor turns OFF when inverter is stopped, during coast
stop, and DC braking.

Set Frequency

When the set frequency is reached (inverter is up-to-speed),

Detection Signal

FAR-CME will be ON. See Function Code 36.

Optional Detection of

FDT-CME will be on when the output frequency is larger than the set

Frequency Level

detection frequency; FDT-CME will be OFF when output frequency
is less than set frequency. See

Code 35.

lnverter Overload Early OL-CME will be on when the output current is larger than the set
Warning Signal

value; OL-CME will be OFF when output current is less than set

current. See Function Code 32.

LV-CME will be on when an undervoltage condition exists. LV-CME

will be off when the DC link voltage is above the trip threshold. N o
output will occur for a set time after power-up.

Run Relay Dry Contact Contact is closed when the inverter is running. (Contact rating:
output

250 VAC, 0.3 Amps inductive cos theta 0.3)

Fault Relay Dry
Contact Output

During normal operation, the relay is not energized and contact is
made between

and 30C. When a fault is detected, the relay is

energized and contact is made between 30A and 30C. (Contact

rating: 250 VAC, 0.3 Amps inductive

cos theta 0.3)

*Open collector outputs are

circuits

50mA maximum ratings. Power for these circuits

must be provided via an external power supply when using them to control external relays (see Figure 4-13.)

The Relay Option

has this power supply built in.
