Magnetek DSD 412 - Display Monitor Functions

DISPLAY MONITOR FUNCTIONS
64
Function #192
F413 DETECT LVL
Units: PU
Range: 0.05 - 0.50
Default: 0.05
This parameter sets the level of difference of
the field current reference and the feedback
at which the drive will display the F413
warning. If all of the criteria is correct in the
field circuit and in the parameter setup the
F413 warning should not appear. The
tracking error can be monitored on F620. If
the error is out of tolerance due to low or
sagging line voltage and the issue cannot be
resolved increase this parameter to
eliminate the warning. This level is in PU
where #50 rated field amps = 1.0PU
ie. 0.05 would correlate with 5% difference
between the feedback and the reference.
Display Monitor Functions
Function # 600
Car Speed
Units: -
This display is the measured velocity of the
elevator. Units are as set in function 17.
Function # 601
Motor Speed
Units: RPM
This display is the measured elevator motor
RPM.
Function # 602
Dictated Speed Reference
Units: -
This display is the reference velocity after
accel/decel rate control conditioning. Units
are as set in function 17.
Function # 603
Pre-Torque Input
Units: %
This display is the pre-torque reference as
applied to starting the velocity regulator.
The value is latched to display the pre-
torque value used at the start of a run. Prior
to a start, the displayed value is that of the
analog or serial link input. This function
works only when pre-torque enable control,
functions 114 is turned ON. Units are a
percent of Rated Motor Amps.
Function # 609
CEMF Vdc
Units: VDC
This display is the CEMF of the motor
calculated from measured motor voltage,
current and armature circuit resistance
functions 4.
Function # 610
Motor Armature V
Units: VDC
This display is the measured voltage output
to the motor armature circuit.
Function # 611
Motor Arm Current
Units: Amps DC
This display is the measured drive output to
the motor armature circuit.
Function # 612
Motor Field Current
Units: Amps DC
This display is the measured motor field
current.
Function # 613
Measured Motor Resistance
Units: OHMS
This is the measured motor armature circuit
resistance calculated during self-tune.
Function # 614
Measured Motor Inductance
Units: HENRIES
This is the measured motor armature circuit
inductance calculated during self-tune.
Function # 615
Measured Field L/R Time Constant
Units: Seconds
This is the motor field time-constant
measured during self-tune.
