Description
Selects the source of the motor pre-heat on/off command.
See section Pre-heating
Note: The pre-heating function does not activate if
• the Safe torque off function is active,
• a fault is active,
• less than one minute has elapsed after stopping, or
• PID sleep function is active.
Pre-heating is deactivated when the drive is started, and
overridden by pre-magnetization, post-magnetization or
continuous magnetization.
0 = Pre-heating is inactive
1 = Pre-heating is active
0. Pre-heating is always deactivated.
1. Pre-heating is always activated when the drive is stopped
(apart from conditions stated above).

Source selection (see Terms and abbreviations
page 152).
Defines the motor pre-heating current that is fed into the
motor when the source selected by
source is on. The value is in percent of the nominal motor
current.
Pre-heating current.
The motor can be automatically started after a short supply
power failure using the automatic restart function. See
section Automatic restart
When this parameter is set to 0.0 seconds, automatic
restarting is disabled. Otherwise, the parameter defines the
maximum duration of the power failure after which restarting
is attempted. Note that this time also includes the DC pre-
charging delay.
WARNING! The function restarts the drive
automatically and continues operation after a supply
break. Make sure that no dangerous situations can
occur.
Automatic restarting disabled.
