Update rate Background
In addition to monitoring the IGBT junction temperatures the drive includes a thermal protection system to protect the other components within the
drive. This includes the effects of drive output current and DC bus ripple. The estimated temperature is displayed as a percentage of the trip level in
this parameter. If the parameter value reaches 100% an Oht3 trip is initiated.

An additional thermal monitoring point is provided in UNISP6xxx and UNISP7xxx drives. The temperature is displayed in this parameter in degrees C.

Update rate Background read
When analogue input 1 is calibrated the number of V to F converter counts is measured by the drive over 64ms and the result is stored in this
parameter. The maximum input frequency is 2.4MHz, and so the maximum for this parameter is 153600. If calibration is performed so that the drive
10V reference is used this parameter is zero. It should be noted that although the input frequency for a 10V input is nominally 2.0MHz the resolution
is not given by 2.0MHz x sample period, but due to the structure of the V to F system the resolution is 500kHz x sample period.
