(Speed Command) Monitors the speed command before the 
speed reference generator (input to the S-Curve).  This command 
comes from either multi-step references, speed command from 
analog channel, or the serial channel. 

ft/min or m/s 

N 

(Speed Reference) Monitors the speed reference being used by 
the drive. This is the speed command after passing through the 
speed reference generator (which uses a S-Curve). 

ft/min or m/s 

N 

(Speed Feedback) Monitors the speed feedback coming from the 
encoder.  It is based on contract speed, motor rpm and encoder 
pulses per revolution.  The drive converts from motor RPM to 
linear speed using the relationship between the CONTRACT CAR 
SPD (A1) and CONTRACT MTR SPD  (A1) parameters. 

ft/min or m/s 

N 

(Speed Error) Monitors the speed error between the speed 
reference and the speed feedback.  It is equal to the following 
equation:

(Pre-Torque Reference) Monitors the pre torque reference, 
coming from either analog channel #2 or the serial channel.

(External Torque Command)  Monitors the Torque Feed Forward 
Command when used.

(Speed Regulator Torque Command) Monitors the speed 
regulator’s torque command.  This is the torque command before 
it passes through the tach rate gain function or the auxiliary torque 
command.  It is the torque required for the motor to follow the 
speed reference.

(Tachometer Rate Command) Monitors the torque command from 
the tach rate gain function, (if used).

command from auxiliary source, when used.
