You can pre-empt the automatic compensation by issuing a Rezero Unit
command (01 ). The drive performs the thermal calibration and then sets
H
a timer and waits 2 minutes before performing the calibration again.
Thermal compensation increases the execution time of the command
during which it is performed by 100 msec (typ) to 350 msec (max).
