Preliminary User Manual UMAX023241 - Version: 1.1 61-63
4.3. Outputs
CAN CANopen
Universal Outputs
Two independent software controlled outputs selectable as:
Proportional Current; Hotshot Digital; PWM Duty Cycle;
Proportional Voltage; or On/Off Digital types
Half-bridge outputs, current sensing, grounded load.
High side sourcing up to 3A
All output types have configurable minimum and maximum output levels within the
range for the type selected.
Current Outputs: 1mA resolution, ac/- 2% error
Software controlled PID current
Range 0 to 3000 mA
Fully configurable dither superimposed on top of output current
Configurable from 50 to 400Hz amplitude
High frequency output drive at 25kHz
Voltage Outputs: 0.1V resolution, ac/- 3% error
Average voltage output based on unit power supply
High frequency drive at 25kHz
Additional external filtering is required to create a DC voltage
PWM Outputs: 0.1% resolution, ac/- 1% error
Range 0 to 100%
Output Frequency: 1 Hz to 25 kHz
Configurable frequency ONLY if no current output types are used, otherwise default
25kHz is used
Digital On/Off:
Load at supply voltage must not draw more than 3A.
Response Time
Contact Axiomatic.
Protection
Fully protected against short circuit to ground or +Vps
Grounded short circuit protection will engage at 4.5A +/- 0.5A.
Unit will fail safe in the case of a short-circuit condition, and is self-recovering when
the short is removed.

Diagnostics
Each input and output channel can be configured to send diagnostic messages to
the J1939 CAN network if the I/O goes out of range. Diagnostic data is stored in a
non-volatile log. Refer to the User Manual for details.
Additional Fault Feedback
There are several types of faults that the controller will detect and provide a
response: unit power supply undervoltage and overvoltage, microprocessor over
temperature and lost communication. They can be sent to the J1939 CAN bus.
Control Logic
User configurable functionality using Electronic Assistant® service tool
Communications
Compliant to CANopen Standards
1 CAN port (CANopen®)
SAE J1939 models are available.
CAN User Interface
EDS File
Standard CANopen tools (not supplied)
CAN Response Time
Per the J1939 standard, the maximum recommended transmit rate for any message
is 10ms. Response time of feedback on the CAN to changes at the I/O will be a
combination of the I/O type’s response time and the configurable software filtering,
ramps, delays, etc. that were selected in the application.
Reflashing Software over CAN
Reflash software over the CAN bus using the Electronic Assistant®.
