Specifications

This parameter selects the starting method for the drive, and can be set for one of the

following:

NORMAL The drive will start when the appropriate contact closure is made on the

terminal strip (REMOTE mode), or by pressing the keypad START key

(LOCAL mode). To start the drive in NORMAL mode, a start command

must be issued at least two seconds AFTER input power is applied.

POWER UP The drive will automatically start upon application of input power. The

drive MUST be set up for a two-wire start/stop circuit (refer to Section

14.0 - CONTROL WIRING), and the start command MUST be present

when power is applied for this function to operate.

AUTO 1 FLYING AUTO RESTART - LOW performance. Synchronization in

approximately 6 seconds with current levels up to 50% of the drive

rating. This setting results in a slow, smooth synchronization.

AUTO 2 FLYING AUTO RESTART - MEDIUM performance. Synchronization

in approximately 1 second with current levels up to 50% of the drive

rating. This setting allows faster synchronization while retaining

smoothness.

AUTO 3 FLYING AUTO RESTART - HIGH performance. Synchronization in

approximately 1 second with current levels up to 100% of the drive

rating. This setting allows the fastest synchronization, but sacrifices

smoothness.

The AUTO 1 - 3 settings allow the drive to start into a spinning load after a fault or upon

application of input power. As with POWER UP, the drive MUST be set up for two-wire

start/stop control and the start command MUST be present after a fault or when power is

applied for this function to operate.

POWER UP and AUTO 1 - 3 settings are only active when the drive is in REMOTE mode

(see Parameter 30 - CONTROL).

When set for AUTO 1, 2, or 3, the drive will attempt five restarts after a fault. During the

interval between restart attempts, the drive will display START PENDING to indicate that

the equipment will automatically restart. If all five restart attempts are unsuccessful, the

drive will trip into FAULT LOCKOUT, which requires a manual reset. Every 15 minutes

that passes will decrement the restart counter by one. Therefore, 75 minutes after a

successful restart, the restart counter is fully reset, and the drive can once again attempt five

restarts.
