Secondary Motor Control
PowerFlex® 755T products support user-configuration of a secondary motor
control profile that provides application flexibility.
Overview
Secondary Motor Control functionality is added to PowerFlex 755T drives as
modular control profiles in firmware revision 5 and later. The Secondary Motor
Control modular control profile is installed in port 11 of the PowerFlex 755T
drive. When defining the motor control type to be used with the Secondary
Motor Control profile, only parameters for that type of motor control are present
in the profile, similar to port 10 Primary Motor Control. When used with the
primary motor control profile, you can define different control types, motor
types, or motor parameters to increase the flexibility of the PowerFlex 755T
drive.
Secondary Motor Control
Configuration
The Secondary Motor Control modular control profile in port 11 is defined in
0:67 [Sec MtrCtrl Mode]. The same motor control types that are available in the
primary motor control profile are configurable in the secondary motor control
profile. Motor control profiles include Induction VHz, Induction SV, Induction
Economizer, Induction FV, IPM FV, and SPM FV. The active motor control type
that is configured in the Secondary Motor Control profile port 11 is displayed in
0:68 [Sec MtrCtrl Act].
The motor control type that is defined for the Secondary Motor Control profile
determines the parameters that are accessible in port 11. All motor data and
application tuning configuration of the Secondary Motor Control profile is done
in port 11. You can see the parameter list in the PowerFlex 750-Series Drives with
TotalFORCE Control programming manual, publication 750-PM100
