signal input from FWD, REV terminals is held internally.

(Operation From
Momentary Contacts)

RST

Reset Signal Input

After removal of fault condition, Faults are reset when a momentary
contact closure is made between the RST-CM terminals for more than
0.1 seconds.
NOTE:

If there is an input to the FWD and/or REV terminals, the unit

will not RESET.

THR

External thermal trip

With THR-CM (open), OH2 trip will occur and the motor will

coast-to-stop.
NOTE:

With no external thermal relay or external braking resistor

thermostat, the THR-CM terminals must be closed or the drive
will not operate. OH2 is a latched fault.

FMA

Frequency Meter

Provides an output of 0 to +10 VDC (+10Vdc at max. frequency.)

Connection Points

Available for connection of a voltmeter (with internal resistance of

Analog

10K ohms.) See Function Code 46 for monitoring selection. Meter
connects between terminal FMA & 11. Two (2) voltmeters, each having
an internal resistance of 10K

Ω

can be connected in parallel.

FMP

Frequency Meter

Pulse frequency output equal to drive output frequency multiplied

Connection Points

by the set value of Function Code 43. Meter connects between FMP

Pulse

and CM.

AX1

Run Relay Dry

Contact is closed when the drive is running. (Contact rating

AX2

Contact Output

resistive load: 250 VAC, 0.3 Amps.) (Only applicable to 40 Hp and greater)

30A

Fault Relay Output

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

30B

Terminals

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

30C

and contact is made between 30A and 30C. (Contact rating resistive
load: 250 VAC, 0.3 Amps.)
