161 Sleep Config Alarm 2 There is a Sleep/Wake configuration error. With Sleep Wake Mode =
Direct, possible causes include:
Drive is stopped and Wake Level < Sleep Level.
Stop=CF, Run, Run Fwd, or Run Rev is not configured in Digital Input
functions.

168 HeatSinkUnderTmp Resettable
Fault Heatsink temperature sensor is reporting a value below -18.7 °C (-1.66
°F) or the sensor feedback circuit is open.
See P943 [Drive Temp Pct] and/or P944 [Drive Temp C].
169 PWM Freq Reduced Alarm 1 The PWM Frequency has been reduced from the value set in P38 [PWM
Frequency] due to excessive IGBT junction temperatures.
See also P420 [Drive OL Mode].
170 CurLimit Reduced Alarm 1 The current limit value has been reduced from the value set in [Current
Limit n] due to excessive IGBT junction temperatures or P940 [Drive OL
Count] = 95%.
