Function
When 3-wire operation is selected and HLD-CM is closed, the pulse
signal input from FWD, REV terminals is held internally.
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.
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.
Provides an output of 0 to +10 VDC (+10Vdc at max. frequency.)
Available for connection of a voltmeter (with internal resistance of
10K ohms.) See Function Code 46 for monitoring selection. Meter
connects between terminal FMA & 11. Two (2) voltmeters, each having
an internal resistance of 10KΩ can be connected in parallel.
Pulse frequency output equal to drive output frequency multiplied
by the set value of Function Code 43. Meter connects between FMP
and CM.
Contact is closed when the drive is running. (Contact rating
resistive load: 250 VAC, 0.3 Amps.) (Only applicable to 40 Hp and greater)
During normal operation, the relay is not energized and contact is made
between 30B and 30C. When a fault is detected, the relay is energized
and contact is made between 30A and 30C. (Contact rating resistive
load: 250 VAC, 0.3 Amps.)
