The Amps field reports the current measured at each channel. The Peak Amps field will

store the highest measured Amp value from the moment the program began or from the

time at which the peak was reset using the Clr Peak button. Motor Amps is a calculated

estimated value based on the batter amps and the current power level. See “Battery Cur-

rent vs. Motor Current” on page 39.

The Power field displays the power level that is actually being applied to the motor. This

value is directly related to the motor command except during current limitation, in which

case the power level will be the one needed to keep the Amps within the limit. Note that

the display value is not signed and thus does not provide rotation direction information.

The Ana fields contain the analog input values that are measured and reported by the con-

troller. When the controller is in the position mode with Analog Feedback, the Ana1 and

Ana2 fields will display the position sensed on the feedback potentiometer. When in speed

mode, these fields display the measured speed by the tachometers. When the controller is

in Analog command mode, the Ana 1 and Ana 2 show the vale of the command potentiom-

eter, while the feedback is on Ana 3 and Ana 4.

In all other modes, this field will display the value at the analog input pin. A small button

next to this field will toggle the display caption, and change the conversion algorithm from

raw analog, to volts or temperature.

Note that in order to measure and display the external temperature or voltage, the proper

external components must be added to the controller. See “Connecting External Ther-

mistor to Analog Inputs” on page 57 and “Using the Analog Inputs to Monitor External

Voltages” on page 58.

The Te m p field displays the temperature for each channel

The Bat Volt field displays the main battery’s voltage.

The Ctrler Volt field displays the controller’s internal regulated 12V voltage.

4- Real-Time Strip Chart Recorder

This chart will plot the actual Amps consumption and other parameters as measured from

the controller. When active, the chart will show measurement during the last five seconds.

Traces for most parameters can be displayed or hidden by clicking on the checkboxes found

next to their numeric fields.

5- Transmit and Receive Data

These two fields show the data being exchanged between the PC and the controller. While

these fields are updated too fast to be read by a person, they can be used to verify that a

dialog is indeed taking place between the two units.

After the Start button is pressed, the Tx field will show a continuous string of commands

and queries sent to the controller.

The Rx field will display the responses sent by the controller. If this field remains blank or is

not changing even though the Tx field shows that data is being sent, then the controller is

Off or possibly defective. Try resetting the controller and pressing the Run/Stop button.

These two fields are provided for quick diagnostic. Use the Console Tab for full visibility on

the data exchange between the controller and the PC.
