Control and Signal Wiring (cont.)
Drive Alarm
These terminals allow internal drive supplied alarm contacts to be used in
external circuits. The contacts are shown in the de-energized (alarm) state.
When the drive is powered up and no alarm is present, the contacts will
change state: 16 to 17 will open, 17 to 18 will close.
Both the N.C. and N.O. contacts will change state
(16 to 17 will close, 17 to 18 will open) when the drive has detected an
alarm or power is removed from the drive.
Resistive rating: 120V AC or 30V DC, 5.0 amps
Inductive rating: 120 V AC or 30V DC, 2.0 amps
Drive Alarm Conditions are:
•
Drive output current is above 150% of rated current.
•
Drive output current is above the MOPC limit set by Parameter 36.
•
Bus voltage is above 110% of nominal input voltage. A continued rise in
bus voltage may result in Parameter 11 Decel Frequency Hold affecting
the decel ramp, or fault F05 Bus Overvoltage.
•
Bus voltage is below 85% of nominal input voltage.
•
Precharge not complete.
•
Parameter 14 Auto Restart is active.
