Settings of the pre-charge function
NOTES
During the pre-charge operation, it is regarded as integrated value=estimated value. The motor
speed may drop shortly from the automatic switchover frequency depending on the parameter
settings.
Parameter changes and switchover to the second PID control are applied immediately. If PID con-
trol has not started when the settings were changed, PID control starts with changed settings. (If
PID control has already started, these settings do not apply. If the changed settings already satis-
fies a condition to start PID control, the PID control starts as soon as these are changed.)
The pre-charge also ends when PID control is set to invalid, the start command has been turned
OFF, and output has been shut off.
