Boolean
Description: True
The MCU has detected a stall condition.
False
There is no current active stall condition.
A stall condition occurs when the motor is producing large amounts of torque, but the vehicle is
not moving. This creates a condition in which the IGBT switches are in danger of being damaged
by overheating.
The MCU handles this situation by limiting the output torque to 10% of its normal value for 30
seconds. It then allows normal torque until the stall conditions are met again.
The probability of encountering this situation is greatly reduced by configuring the MCU to use a
low PWM frequency (see the Stall data in the EC- EM-PMI318B User’s Manual for more
details).

Boolean
Description: True
The MCU is operating in an open loop configuration.
False
The MCU is operating in a closed loop configuration.
When the MCU detects certain errors in its feedback control loops (usually a problem with
sensors or circuitry), it maintains the ability to provide some drive power to the vehicle but
severely limits the amount of torque it will make available.
