Drive OL JnctTmp

Displays the calculated junction temperature of the power semiconductors in the inverter.
The calculation uses the values of Par 313 [Heatsink Temp], Par 358 [Iq Ref Limited], and
inverter thermal characteristics contained in the power EE memory. If this value exceeds
the maximum junction temperature (visible in Par 348 [Drive OL TP Data] when Par 347
[Drive OL TP Sel] = 12 “fJunTmprMax”), two faults occur: Inverter Overtemperature Fault
(fault code 15), and Junction Overtemperature Fault - indicated by bit 7 [Jnc OverTemp] of
Par 346 [Drive OL Status].

Drive OL Status

Indicates the status of various overload (OL) conditions.

• Bit 0 [NTC Shorted] indicates the Negative Temperature Coefficient (NTC) device has a short circuit.

• Bit 1 [NTC Open] indicates the NTC has an open circuit.

• Bit 2 [HS OverTemp] indicates that the heatsink temperature is above 105C for ratings 1.1-11.0A, 115C for 14-34A, or 100C for 40-52A.

• Bit 3 [HS Pending] indicates that the heatsink temperature is above 95C for ratings 1.1 -11A, 105C for 14- 34A, or 90C for 40- 52A.

• Bit 4 [IT Trip] indicates the drive has exceed the 3 second rating of either the 150% normal duty rating or 200% of the heavy duty rating.

• Bit 5 [IT Pending] indicates the drive OL integrator is at 50% of the time out time.

• Bit 6 [IT Foldback] indicates the drive closed loop current limit is in a fold back condition. The value of the fold back is proportional to the calculated junction

temperature.

• Bit 7 [Jnc Over Temp] indicates the junction temperature has exceeded the maximum temperature for the power semiconductor device.
