Control Board Parameter Settings
The Control Board comes from the factory pre-loaded with firmware and initial configuration parameter settings and is
essentially ready to use right from the package. The following is a list of configurable parameters that may be adjusted using the
Cascadia RMS GUI (Graphic User Interface) software. See Appendix at end of this manual for more info.
Active inverter HV discharge is disabled by default. It is imperative that active discharge only be enabled once
correct VCU contactor sequencing control has been established. Having HV contactors closed with HV still present to
the inverter will damage the inverter's discharge hardware. The active discharge is triggered via an on-board relay
output. This output will go into an uncontrolled state during programming thus it is imperative that HV not be
present to the inverter any time the inverter is put into programming mode.
Except for enabling active HV discharge, setup changes to the Control Board using the RMS GUI is typically not
needed in most cases and the default settings should work very well as they are.

motor control settings.

Relay output to trigger inverter HV discharge. Default setting is OFF. Must be
enabled for active HV discharge to function – see WARNING above. Value is
shown in Hex. Default value is 0x000C. Change to 0x002C to enable.
Must be enabled for active inverter HV discharge to function – see WARNING
above. Default setting is OFF.
Used to set CAN ID offset if using multiple controllers on the same CAN network.
Default offset is 0x0A0. Range of CAN IDs is 0x0A0 – 0x0CF.
Sets the HV under-voltage fault threshold voltage. Set to 0 to disable HV under-
voltage fault function. HV under-voltage protection typically handled by VCU.
Sets the inverter temperature limit in °C x 10. The inverter temp is sampled from
each of the 3 power phase module temp sensors. If temperature exceeds this
value, the inverter will go into a fault state. Hard coded with a max value of 80°C.
Sets the motor temperature limit in °C x 10. There motor temp is sampled from
each of the 2 stator temp sensors. If temperature exceeds this value, the inverter
will go into a fault state. Hard coded with max value of 180°C.
Sets the temperature threshold below which full torque is available. As the motor
temperature increases from Full Torque Temp to Zero Torque Temp, the allowed
motor torque is decreased linearly. Temp based derating typically handled by
VCU – can use this function as a backup.
Sets the temperature where motor torque will be limited to zero. Temp based
derating typically handled by VCU – can use this function as a backup.
