Description: True
The MCU is operating in the Limp Home Mode.
False
The MCU is not operating in the Limp Home Mode.
When the MCU detects a serious impairment to its normal operation (inaccurate position signal,
IGBT switch problems, etc.), it enters Limp Home Mode. Limp Home Mode allows continued but
reduced operation as safely as possible given the impairment. The torque delivered will be
limited by the Limp Home Percentage, which is a percentage of the maximum torque possible at
each speed and voltage point. See the Danfoss Power Solutions EC- EM-PMI318B User
Manual for more details.

Units:
Boolean
Description: True
The MCU’s ADC calibration integrity check failed.
False
The MCU’s ADC calibration integrity check passed.
This test is performed only at power up. Upon failure, the MCU uses default calibration data and
severely limits torque output capability. A power cycle is required to clear this error
