X***:STALL TIME

Motor stall is used to protect a motor that is frozen or overloaded. If left in this

condition, the motor can be permanently damaged.

Motor stall will fault out the drive if parameter Y***:STALL PROT is enabled. A stall

condition is realized when:

Actual % Armature Current > X***:STALL % AMP

Motor Speed (In Process Units) < X***:STALL SPEED

Elapsed Time > X***:STALL TIME

When a motor stall is determined, digital data bit D***:MOTOR STALL turns on

regardless of Y***:STALL PROT bit status. This bit can then be configured to a digital

output for run removal.

X***:DC VT SCALE

When using the ADDvantage-32 PLUS AFM (DC0001-XXXX-X) module, several

parameters must be set so that the module can control the bridge current properly. The

existing bridge's rating must be known as well as the turns ratio of the feedback CT's, the

burden resistor value, and voltage feedback scaling. (Paragraph 3.19.3, AFM CURRENT

TRANSFORMER PHASING PROCEDURE, has steps to determine or calculate

necessary values, if unknown.) These values must be accurate or the bridge will not be

controlled properly.

When a standard ADDvantage-32 PLUS is being used (DC0010 through DC2500), these

parameters should be left at default.
