This is the setpoint parameter used for this test. When controlling
by speed or torque, the internal circuitry of the controller closes
the loop on the desired setpoint. The PID controls are fully active
for system response tuning.
Speed Range (0 - n)
The value entered should be slightly greater than the free run
speed of the motor. Adjusting the speed range properly will give
the best dynamic range for the PID settings.
Setpoint (0 - n)
The initial value for the Control Parameter.
Delta Value (0 - n)
The amount of change in the setpoint value from one cycle to the
next.
% of Setpoint (0 - n)
The percentage of initial setpoint change from one cycle to the
next.
When controlling by other parameters, M-TEST 7 uses a
proportional control loop in conjunction with the open loop mode of
the controller.
Stable for (0 - n)
The length of time, in minutes, the motor temperature has to
remain within the Termination Delta T value to be considered
thermally stable.
Test Duration (0 - n)
The overall length of test in minutes.
Sampling Rate (0.01 - n)
The time interval at which a data point will be stored. The
maximum rate is 0.01 seconds (100 samples per second). Realtime data will be displayed in the data table and plotted on the
graph. This data is not affected by the sampling rate.
Maximum Analog Input
(0 - n)
The high limit for the accessory analog input device. A reading
that exceeds this value will cause the test in progress to abort.
Maximum Motor Current
(0 - n)
The high current limit for the power measurement device. Any
current that exceeds this value will cause the test in progress to
abort.
Maximum Temperature
(0-n)
The maximum temperature limit for the temperature measurement
device. Any temperature that exceeds this value will cause the
test in progress to abort.

TEST SETUP
Termination Delta T (0 - n) The temperature span at which the motor is considered to be
thermally stable.
