Detailed descriptions
SPEED COMMAND
(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.
SPEED REFERENCE
(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).
SPEED FEEDBACK
(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.
SPEED ERROR
(Speed Error)
Monitors the speed error between the speed
reference and the speed feedback. It is equal to
the following equation:
error
speed
feedback
speed
reference
speed
=
−
PRE-TORQUE REF
(Pre-Torque Reference)
Monitors the pre torque reference, coming from
either analog channel #2 or the serial channel.
SPD REG TORQ CMD
(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.
TACH RATE CMD
(Tachometer Rate Command)
Monitors the torque command from the tach rate
gain function, (if used).
AUX TORQUE CMD
(Auxiliary Torque Command)
Monitors the feedforward torque command from
auxiliary source, when used.
EST INERTIA
(Estimated Inertia)
Estimated elevator system inertia.
