30 CONTROL (START/STOP CONTROL)
WARNING!
If CONTROL is set to LOCAL, TB-1 is disabled and CANNOT be used
as a STOP switch! Incorrect use of TB-1 may result in damage to
equipment and/or injury to personnel!
WARNING!
STOP ( TB-1) and EXTERNAL FAULT ( TB-13D) circuitry may be
disabled if parameters are reset to factory defaults! The drive must be
reprogrammed after a RESET in order to insure proper operation (see
Parameter 65 - PROGRAM).
FAILURE TO DO SO MAY RESULT IN DAMAGE TO EQUIPMENT
AND/OR INJURY TO PERSONNEL!
This parameter is used to select the source of the start/stop command and direction
control. The following settings are available:
LOCAL
START/STOP and FORWARD/REVERSE commands from
the keypad only.
REMOTE START/STOP and FORWARD/REVERSE commands from
the terminal strip only.
BOTH LOCAL operation if TB-13A or TB-13C is programmed for
LOCAL SELECT and a contact closure is made from TB-13A
or TB-13C to TB-2. If the contact closure is not made, the drive
will be in REMOTE mode.
31 UNITS (SPEED/PID UNITS)
UNITS sets the units of the output speed or PID display on the keypad.
The following choices are available:
Speed mode: HERTZ, RPM, %HZ, /SEC, /MIN, /HR, GPH, NONE
PID mode:
%, PSI, FPM, CFM, GPM, IN, FT, /SEC, /MIN, /HR, F, C,
MPM, GPH
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. If one of the "speed" units is selected, but PID MODE is ENABLED
and the drive is in Auto mode, the displayed PID units will default to %.
32
HZ MULT (HERTZ MULTIPLIER)
The HZ MULTIPLIER is used to scale the output speed indication on the display.
If UNITS is set for HERTZ or % HZ, this parameter has no effect. Multiplying the
output frequency by the HZ MULTIPLIER will yield the desired speed value on the
display.
Example: The desired speed units is RPM with a standard 60 Hz, 1800 RPM motor.
Set UNITS to RPM and set HZ MULT to 30.00. This will result in a speed display
of 1110 RPM for an output frequency of 37 Hz (37 Hz X 30 = 1110 RPM). Also, if
there was a 100:1 gear reducer in the system, Parameter 33 - SPEED DP below
could be set to XX.XX to represent the output of the gear reducer (11.10 RPM in
the example).
