Parameters 141
Standstill 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.

Turning 2 This mode is like Turning autophasing mode with the
difference that at the end of turning autophasing
routine, rotor turns by 180 electrical degrees.

21.14 Pre-heating input
source
Selects the source for triggering pre-heating for the
motor. The status of the pre-heating is shown as bit 2
of
06.21 Drive status word 3
.
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.
Off
Off 0. Pre-heating is always deactivated. 0
On 1. Pre-heating is always activated when the drive is
stopped.

21.15 Pre-heating time delay
Time delay before pre-heating starts after the drive is
stopped.
60 s
