Description
The standstill modes can be used if the motor cannot
be turned (for example, when load is connected).
Notes:
•
For SynRM, PMaSynRM, and internal permanent
magnet motors, autophasing time is usually less
than 1 second.
• For surface permanent magnet motors,
autophasing time is usually from 1 to 2 seconds.
Also, pulsating torque up to the nominal torque is
produced in this type of motor and therefore loud
noise may occur.
This mode is like Turning autophasing mode with the
difference that at the end of turning autophasing
routine, rotor turns by 180 electrical degrees.
Selects the source for triggering pre-heating for the
motor. The status of the pre-heating is shown as bit 2

of
Notes:
• The heating function requires that STO is not
triggered.
• The heating function requires that the drive is not
faulted.
• Pre-heating uses DC hold to produce current.
0. Pre-heating is always deactivated.
1. Pre-heating is always activated when the drive is
stopped.
