Note:
The Converter will not start if there are alarms present, or if Terminals B8 (Program Stop)
or B9 (Coast Stop) are low, 0V.
Ensure that Program Stop and Coast Stop are valid before Start/Run is applied.
Advanced Starting Methods

Also refer to the STOP RATES function block: the CONTACTOR DELAY parameter is used to
prevent multiple operations of the main contactor from rapid use of the Jog switch.
