D - C A m p s
Enter the Field Power Module’s D-C Amps output value which can range from 1 to 100 Amps.
There is no default value. This value is found on the Power Module’s nameplate and is used to
scale field current feedback.
Motor Field Ratina Selections
Hot Amps
There is no default value. This is the current that will be generated by the field power supply when
current reference is at maximum. This value is found on the motor’s nameplate and can range
from 0.01 to 99.99 Amps.
Minimum Amps
There is no default value. This is the minimum output current that the field power supply will
produce when it is enabled. This value is found on the motor’s nameplate and can range from
0.01 to 99.99 Amps.
Field Loss Trip Amps
Field Safety Setting Selections
There is no default value. This parameter is the point at which a field loss will be detected and can
range from 0.01 to 99.99 Amps. Refer to register 202/1 202 for more information.
Turn Off Delay (Sec)
This is the amount of time the field will remain energized after a fault condition. The delay can
range from 1 to 300 seconds.
2.2.3 Speed Feedback Data Screen
The Speed Feedback Data Screen allows you to enter specific information about the resolver or
analog tachometer that is connected to the Resolver & Drive I/O module in the PMI rack and that is to
be monitored for overspeed and tach loss conditions. See figures 2.4 to 2.6. Note that if you choose
“No Speed Feedback” the overspeed and tach loss functions will be disabled.
W A R N I N G
THE USER MUST ENSURE THAT THE CORRECT FEEDBACK TYPE HAS BEEN SELECTED DURING
CONFIGURATION. IF “NO SPEED FEEDBACK” HAS BEEN SELECTED, THE USER MUST PROVIDE
AN INDEPENDENT METHOD OF OF DETECTING OVERSPEED, OTHERWISE, A FEEDBACK LOSS
WILL NOT BE DETECTED, RESULTING IN MOTOR OVERSPEED. FAILURE TO OBSERVE THIS
PRECAUTION COULD RESULT IN BODILY INJURYAND IN DAMAGETO, OR DESTRUCTION OF, THE
EQUIPMENT.
