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 affected 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
effects of LOCAL and REMOTE mode when operating the
drive in PID mode.
31 UNITS (SPEED/PID UNITS)
This parameter sets the units of the output speed or the PID display on the keypad. The
following choices are available:
sp HERTZ pid CFM (cubic feet per minute)
sp RPM (revolutions per minute) pid GPM (gallons per minute)
sp %HZ (percent Hertz) pid IN (inches)
sp /SEC (units per second) pid FT (feet)
sp /MIN (units per minute) pid /SEC (units per second)
sp /HR (units per hour) pid /MIN (units 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.
