ADDvantage-32 PLUS ● AC to DC Power Converter
3-35
The ADDvantage-32 PLUS comes supplied with a single phase motor field supply. See
drive rating for full rating of the supply. The standard hardware configuration is a two
SCR, two diode bridge. An optional four SCR bridge can be supplied.
The following parameters set up the field current loop control.
Y***:FLD B-TYPE - Select to the hardware supplied, either two or four SCR
field bridge. Standard is two SCR bridge.
Y***:FLD V-CMD - Defaulted to be the output of the field current loop. If field
voltage control is desired, reconfigure this to a field voltage
reference. Note field loss protection is disabled as soon as
this is changed from default.
X***:MAX FLD ALP - Set to the maximum allowable angle at which the field
SCR's can fire. This parameter should never be changed
without first consulting the factory.
X***:MIN FLD ALP - Set to the minimum allowable angle at which the field
SCR's can fire. This parameter should never be changed
without first consulting the factory.
X***:FLD TX RAT - Set to the ratio of the field supply input voltage vs. the
armature supply input voltage. Used if a step down
transformer is needed to feed the field supply.
X***:FLD LOSS - Set to the percentage of full field current used to trip the
drive out on field loss fault. Defaulted to 25% of full
rating.
X***:FLD PHASE - Degree out of phase the field voltage is from the armature.
Consult Avtron Industrial Automation, Inc., if the field is
supplied from a separate source.
X***:IFLD PGAIN - Proportional gain constant for the field current loop.
Default is adequate for most motors.
X***:IFLD IGAIN - Integral gain constant for the field current loop. Default is
adequate for most motors. Gain is entered in seconds per
repeat.
