1-71 Start Delay
Default value: 00 s
Setup: All setups
Data type: Uint16
Enter the time delay between the start command and the time when the drive supplies the power to the motor. This parameter refers to
the start function selected in parameter 1-72 Start Function. Enter the time delay required before commencing acceleration.

DC hold/motor preheat
Coast
Description
Estimates the electrical angle of the rotor and uses this as a
starting point. Standard selection for automation applications.
The parking function applies DC current across the stator
winding and rotates the rotor to electrical 0 position (typically
selected for HVAC applications). Parking current and time are
configured in parameter 2-06 Parking Current and parameter
2-07 Parking Time.
Combining rotor detection with the parking function.
Estimates the electrical angle of the rotor by sending out test
pulses. If the motor is restarted in less than 1.0 s, this function
does a second measurement. If movement is detected, the start
will be delayed for maximum 10 s.
