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.
ft/min or m/s N
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).
ft/min or m/s N
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.
ft/min or m/s N
MOTOR SPEED
(Motor Speed) Monitors the measured speed feedback coming
from the encoder. ENCODER PULSES (A1) calibrates this
parameter.
RPM N
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
ft/min or m/s N
PRE-TORQUE
REF
(Pre-Torque Reference) Monitors the pre torque reference,
coming from either analog channel #2 or the serial channel.

PRE-TORQ LAST
(Pre-Torque Last Value) Displays the pre-torque used for the
previous run.

EXT-TORQUE
CMD
(External Torque Command) Monitors the Torque Feed Forward
Command when used.

SPD REG TORQ
CMD
(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.

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 INERTI
(Estimated Inertia) Estimated elevator system inertia. seconds N
