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

(refer to Parameter 30 - CONTROL).

When set for AUTO 1, 2, or 3, the drive will attempt ve 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 ve 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 ve restarts.

NOTE 1: When set for AUTO 1, 2, or 3, only the rst two restart attempts will perform

a speed search to start into a spinning load. The last three restart attempts

will apply DC braking (at the voltage level programmed into Parameter 12

- DC BRAKE) for 15 seconds and then start from zero speed.

NOTE 2: The drive WILL NOT restart after a CONTROL or PWR SAG fault. Also, if an

OUTPUT fault occurs below 1.5 Hz, only one restart will be attempted, after

a 30 second delay. If unsuccessful, it will then trip into FAULT LOCKOUT,

which requires a manual reset. This is done to protect the drive in case of

a shorted motor.

26 STOP (STOP MODE)

This parameter selects whether the motor will COAST to a stop, or RAMP to a stop, when

the drive is given a stop command.

COAST When a stop command is given, the drive shuts o the output to the motor,

allowing it to coast to a stop. In this mode, the time it takes the motor to

stop is governed by the inertia of the driven load.

RAMP When a stop command is given, the drive will decelerate the motor to a

stop over a period of time according to Parameter 9 - DECEL. Once the

output frequency reaches 0.0 Hz, there will be a 200 ms delay before the

drive can be started again.

RAMP 2 Same as RAMP, but without the 200 ms start delay. This allows faster start/

stop cycles for applications that require it.

28 AUTO / MAN (AUTO / MANUAL SPEED CONTROL)

This parameter determines how AUTOMATIC and MANUAL speed control is selected,

and aects the functionality of the AUTO/MAN key on the keypad.

A/M LOC The AUTO/MAN key on the keypad is active only when the drive is in LOCAL

mode. In REMOTE mode, the AUTO/MAN key is disabled.

AUTO The drive will respond to a 0-10 VDC signal, 4-20 mA signal, or one of the

four PRESET SPEEDS, depending on the programming of terminals TB-

13A, TB-13B and/or TB-13C. The AUTO/MAN key is disabled.

NOTE: If no AUTO reference is selected using TB-13A, TB-13B or TB-13C,

speed control defaults to the keypad.

MANUAL The drive will respond to the p and q keys on the keypad. The AUTO/

MAN key is disabled.

A/M SPD The AUTO/MAN key is always active.

NOTE: If the drive is switched from LOCAL to REMOTE mode, speed

control will switch to AUTO. If the drive is switched from REMOTE

to LOCAL mode, speed control will switch to MANUAL mode. The

AUTO/MAN key can then be used to select the desired mode.
