In REMOTE mode (terminal strip start/stop control), speed control is only selected
using the TB-13 input selects. For AUTOMATIC speed control, one of the TB-
13 input selects must be set to the desired speed reference, and that terminal must
be closed to TB-2. The drive will then respond to the automatic speed reference.
If none of the TB-13 input selects are closed to TB-2, speed control will default to
MANUAL mode, and the drive will respond to the keypad or speed pot, depending
on Parameter 29 - MANUAL. This will cause the Form C relay or open-collector
outputs to indicate MANUAL mode if set to indicate AUTO/MAN mode.
0 - 10 VDC and 4 - 20 mA INPUT SIGNALS
TB-13A, TB-13B, and TB-13C can all be programmed to select 0-10 VDC or 4-
20 mA input.
PRESET SPEEDS
TB-13A can be programmed to select SPEED #1, TB-13B to select SPEED #2,
and TB-13C to select SPEED #3. Closing any two of these terminals to TB-2 will
select SPEED #4. Refer to Parameters 1-4: SPEED #1 - #4 in Section 18.0 -
DESCRIPTION OF PARAMETERS.
JOG
The JOG function only works when the drive is in REMOTE mode, and only
when the drive is in a STOP condition. TB-13B can be programmed to select
either JOG FORWARD or JOG REVERSE. The jog speed is set by PRESET
SPEED #2. Close TB-13B to TB-2 to JOG, and open the contact to STOP.
MOP - MOTOR OPERATED POT
TB-13A and TB-13B are used for this function, which sets the speed of the drive
using contacts wired to the terminal strip. Program TB-13A to select DEC FREQ,
and program TB-13B to select INC FREQ. Closing TB-13A to TB-2 will activate
the DEC FREQ function, and will cause the speed setpoint to decrease until the
contact is opened. DEC FREQ will operate when the drive is in RUN mode or
STOP mode. Closing TB-13B to TB-2 will activate the INC FREQ function, and
will cause the speed setpoint to increase until the contact is opened. INC FREQ
will only operate when the drive is in RUN mode.
WARNING!
When operating in JOG mode, the STOP key WILL NOT stop the drive. To stop
the drive, the contact between TB-13B and TB-2 must be opened.
