DELAY
.
• Starts the speed regulated motor.
• Starts auxiliary motors. See parameter 8115 for delay.
WARNING!
Motors equipped with star-delta starters require a PFA Start
Delay.
• After the ACH550 relay output switches a motor On, the star-delta
starter must switch to the star-connection and then back to the delta-
connection before the drive applies power.
• Thus, the PFA Start Delay must be longer than the time setting of the
star-delta starter.
