Magnetek TM7310rev01 User Manual

 

(Gain Bandwidth Armature) If 
GAIN SELECTION (C1) is set to 
MANUAL, this parameter is used 
to convert ARM RESISTANCE 
(A4) and ARM INDUCTANCE 
(A4) into the integral and 
proportional gains used by the 
current regulator.  
If GAIN SELECTION is set to 
AUTO-TUNE, this parameter is 
used to convert AUTO MEAS 
ARM R  (D2) and AUTO MEAS 
ARM L (D2) into the integral and 
proportional gains used by the 
current regulator.  The higher the 
setting, the more faithfully the 
regulator will duplicate its input 
command, however, too high of a 
bandwidth can cause problems 
such as a rough ride as the drive 
is more responsive. 

N N 

(Gain Bandwidth Field)  If GAIN 
SELECTION is set to AUTO-
TUNE, this parameter is used to 
calculate AUTO FLD INT  (D2) 
and AUTO FLD PROP (D2) into 
the integral and proportional 
gains used by the field regulator.  
The higher the setting, the more 
faithfully the regulator will 
duplicate its input command, 
however, too high of a bandwidth 
can cause problems such as a 
rough ride as the drive is more 
responsive. 

N N 

(PWM Frequency) 
This parameter sets the PWM or 
‘carrier’ frequency of the motor 
armature portion of the drive.   

N N 

(Cooling Fan OFF Delay) 
Adjusts OFF delay of all cooling 
fans after drive has stopped 
operating when Main Fan Control 
is set at “Automatic”.
