Output Testing

The X20L outputs can be tested live with our Syvecs - Scal program and information on

connecting to the unit can be found in the PC Connection section of the manual. After

connecting to the expander via USB, users will see an area at the bottom of the calibration tree

called output testing.

Here users are able to test the functions of each output by itself without the need for any

master/slave CAN communication.

NOTE:

H-Bridge Output Mode / H-Bridge Output Frequency / Low Side Output Frequency maps

must be set and programmed onto the device for the output testing logic of these outputs to

apply. You cannot change these maps when Output Test Mode Enable is enabled.

Green Maps – Live Adjustable

Blue Maps – Require programming to set

Set a frequency you wish the outputs to be driven at in H-Bridge Output Frequency and Low

Side Output Frequency. Next set the H-Bridge Output Mode and Device - program the X20L.

Output Test Mode Enable can then be enabled.

Now you can then set a duty for each output to be driven in H-Bridge Output Test Duty and Low

Side Output Test Duty. These maps can be adjusted live.

If H-Bridge Output Mode map is set on Full Bridge, the paired outputs used in the full bridge

individually set the drive direction.

For example: Motor is wired to HBR1 and HBR2, Output Mode is set to Full Bridge on HBR1 and

Increasing Duty on HBR1 output duty cell will cause the full bridge to drive the HBR1 output

positive and the HBR2 output negative.

DAC Output Test Voltage is a live map which you can set the voltage that DAC1 -4 are driven at

in Output test mode.
