7A.5.3 Display Parameters - O. Thompson Microflite Ultra 2000 Installation & Adjustment Manual

Microflite Ultra 2000 - Magnetek DSD 412 DC Drive
7a.5.3 Display Parameters
The following parameters are used to display data in the drive. They can be useful for
troubleshooting the drive to determine what signals the drive is seeing and the magnitude of
the signals. They also allow the drive to be tuned without connecting a meter or Amprobe to
the controller.

This parameter displays the present speed of the car. It is derived from parameter 17, Rated
Speed based on the speed of the motor. It is not an exact value, but rather the value that the
drive thinks the car is moving at.
This parameter displays the present speed of the motor in RPM. It is exact only if parameter 16,
Gearless Ratio, is set correctly and parameter 10, Encoder PPR.
This parameter displays the speed reference signal in feet per minute to the drive.
This parameter displays the magnitude of the pretorque reference signal to the drive.
This parameter displays the amount of counter EMF of the motor armature.
This parameter displays the present motor armature voltage.
This parameter displays the present motor armature current in amperes.
This parameter displays the present amount of motor field current.
This parameter displays the measured motor armature resistor. It is measured during the self
tune procedure.
This parameter displays the measured motor armature inductance. It is measured during the self
tune procedure.
This parameter displays the measured motor field time constant. It is measured during the self
tune procedure.
This parameter displays the amount of speed error the drive is presently seeing.
This parameter displays the observes frequency of the AC line in Hertz.
This parameter displays the observed temperature of the heat sink assembly in degrees C.
This parameter displays the present voltage of the AC line.
This parameter displays the version of the software installed in the drive.
