Parameter Descriptions
TORQ DMD ISOLATE
PREF: 78.16
Default: FALSE
Range: FALSE / TRUE
Selects between Speed Control mode and Torque Control mode. When TRUE, (Torque Control mode) the torque demand
output from the speed loop block is the sum of the Direct Input plus the AUX TORQUE DMD parameter.
TOTAL SPD DMD RPM
PREF: 78.17 Default: —.xx rpm Range: —.xx rpm
This diagnostic shows the final values of the speed demand in rpm obtained after summing all sources. This is the value
which is presented to the speed loop.
TOTAL SPD DMD %
PREF: 78.18 Default: —.00 % Range: —.00 %
This diagnostic shows the final values of the speed demand as a % of MAX SPEED obtained after summing all sources. This
is the value which is presented to the speed loop.
SPEED ERROR
PREF: 78.19 Default: —.00 % Range: —.00 %
Shows the difference between the demanded speed and the actual speed as a % of MAX SPEED.
TORQUE DEMAND
PREF: 78.20
Default: —.00 %
Range: —.00 %
Shows the demanded motor torque as a percentage of rated motor torque.
DIRECT INPUT
PREF: 78.21 Default: —.00 % Range: —.00 %
Shows the value of the Direct Input, after scaling and clamping.
PHASE INPUT
PREF: 78.26 Default: —.00 % Range: —.00 %
Shows the value of the Phase PID Output connected internally.
