29 MANUAL (MANUAL)

This parameter selects the speed reference source when the drive is set for MANUAL speed control (see

parameter 28 - AUTO/MAN above). The speed reference options are KEYPAD (UP and DOWN ARROW

keys), or 0 - 10 VDC (from a speed pot wired to TB-2, 5A, and 6; or some other 0-10 VDC source).

30 CONTROL (START/STOP CONTROL)

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!

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

explains the possible settings:

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 UNITS)

HZ UNITS sets the units of the output speed display on the keypad. This parameter can be set to the

following speed units: HERTZ, RPM, % HZ, /SEC, /MIN, /HR, GPH and NONE.

NOTE: The intended use of "/SEC", "/MIN", and "/HR" are units per second, units per minute, and units

per hour.

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: If the desired speed display is RPM, and a standard 60 Hz, 1800 RPM motor is being used, set

UNITS to RPM and set HZ MULTIPLIER to 30.00. This would 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 in order for the display to read 11.10 RPM,

representing the output speed of the gear reducer rather than motor speed.
