30 CONTROL (START/STOP CONTROL)

This parameter selects the START/STOP control source, which is either the keypad

(LOCAL), the terminal strip (REMOTE), or the serial link (SERIAL). The LOCAL/REMOTE

key on the keypad is also aected by the setting of this parameter. The following settings

are possible:

LOCAL The drive will only respond to START/STOP commands from the keypad.

The LOCAL/REMOTE key is disabled.

REMOTE The drive will only respond to START/STOP commands from the terminal

strip. The LOCAL/REMOTE key is disabled.

SERIAL The drive will only respond to START/STOP commands through the serial

link.

KEYPAD The LOCAL/REMOTE key on the keypad is enabled and is used to toggle

between LOCAL and REMOTE modes. Press the LOCAL/REMOTE key

to select the desired mode and then press the ENTER key within three

seconds.

NOTE: If LOCAL mode is selected, a jumper is required between TB-1

and TB-2 to allow the drive to START.

TB STRIP The terminal strip is used to select LOCAL or REMOTE mode. LOCAL mode

if TB-13A or TB-13C is set for LOCAL SELECT and a contact closure is

made between TB-13A or TB-13C and TB-2. If the contact closure is not

made, the drive will be in REMOTE mode.

KEYPAD 2 Acts the same as KEYPAD, but TB-1 is disabled as a STOP input when in

LOCAL mode. Therefore, a jumper is not required between TB-1 and TB-2

to START in LOCAL mode.

NOTE 1: The STOP key on the keypad is always active. The STOP

input at TB-1 is active unless CONTROL is set to KEYPAD

2 and LOCAL mode is selected.

NOTE 2: Refer to Parameter 70 - PID MODE for information on the

eects of LOCAL and REMOTE mode when operating the

drive in PID mode.

sp RPM (revolutions per minute) pid GPM (gallons per minute)

sp GPH (gallons per hour) pid /HR (units per hour)

NONE (no units displayed) pid F (degrees Fahrenheit)

pid % (percent of PID feedback) pid C (degrees Celsius)

pid PSI (pounds per square inch) pid MPM (meters per minute)

pid FPM (feet per minute) pid GPH (gallons per hour)

NOTE: If one of the “pid” units is selected, but the drive is in MANUAL (open-loop)

speed control mode or PID MODE is DISABLED, the displayed speed units

will default to HERTZ.
