Over Temperature Duty Limit
Description
The maximum duty cycle limit for the Over Temperature Response
CAN Name
OVT_RAMP_DTY_MIN
Units
Units are in % duty cycle (%)
Advanced
YES
Over Temperature Limit
Description
The limit at which over-temperature event activation occurs on the controller. The over-temperature response setting defines the behaviour. Note that the controller has a separate hard temperature limit at 135C at which point the controller will shutdown.
CAN Name
TEMP_LIM
Units
Units are in Degrees Celsius (°C)
Advanced
NO
Over Temperature Ramp End Temperature
Description
Temperature at which the ramp should end when using "Power Ramp" Over Temperature Response. At this temperature the maximum duty cycle is limited to Over Temperature Duty Limit.
CAN Name
OVT_RAMP_TEMP
Units
Units are in Degrees Celsius (°C)
Advanced
NO
Over Temperature Response
Description
The response to apply to limit maximum output duty cycle when the temperature limit is reached on the controller. "Power Step" sets the maximum duty to "Over Temperature Duty Limit". "Power Ramp" linearly ramps the maximum duty cycle from 100 at "Temperature Limit" to "Over Temperature Duty Limit" at "Over Temperature Ramp End Temperature". "None" does not apply any limits to maximum output duty cycle. Note that the controller has a separate hard temperature limit at 135C at which point the controller will shutdown.
CAN Name

Units
N/A
Advanced
NO
Value Mappings:
0 -> Power Step
1 -> Power Ramp
2 -> None
Overvoltage Limit Response
Description
Behaviour response when configured over-voltage limit on the bus is triggered. Bus voltage exceeded the limit.
CAN Name
OVV_LIM_RES
Units
N/A
Advanced
YES

2 -> Disabled
Overvoltage Threshold
Description

OVV_START
Units
Units are in Volts (V)
Advanced
YES
Phase Current Limit
Description
The current limit to apply to drive on the phase/output from the controller.

PTC Offset Resistance
Description
Offset resistance calculated by the ESC when using PTC temperature sensors.
CAN Name
PTC_OFST_RES
Units
N/A
Advanced
YES
PTC Reference Temperature
Description
Reference temperature value to calibrate motor temperature measured by the PTC. This value should be the actual temperature of the PTC sensor. When this value is set to non-zero, the PTC temperature calibration runs and calculates the offset resistance, and this value is set back to zero.
CAN Name
PTC_REF_TEMP
Units
N/A
Advanced
YES
Signal Timeout Period
Description
A timeout period where no valid signal is present results in shutting the output drive. The drive will be resumed once a valid signal is returned and the throttle is 0%. If the Arm message timeout period is less than this setting, the Arm timeout period will take precedence.
CAN Name
RX_TIMEOUT
