7. TROUBLESHOOTING
R F
Reverse/Forward key: Selects Forward or Reverse direction.
The R/F key is only active if Parameter 17 - ROTATION is set
to “2” (FORWARD AND REVERSE).
When the R/F key is pressed, the symbol for the opposite
direction will blink on the display. Press the M key within four
seconds to confirm the rotation change.
Below are the display symbols used to indicate direction:
FORWARD REVERSE
6. REMOTE KEYPAD FUNCTIONS
The M key and the ▲ and ▼ keys on the remote keypad function the same
as the Mode button and the ▲ and ▼ buttons on the drive. The other
remote keypad functions are described below:
STOP key: Press STOP to Stop the drive. The STOP key is
active whenever the remote keypad is operational, even if the
remote keypad is only used for programming and monitoring.
RUN key: Press RUN to Start the drive. The RUN key is only
active if the remote keypad is selected as the Start/Stop control
source.
WARNING!
If the remote keypad display is totally blank or is displaying a “JF” fault, the
STOP key WILL NOT stop the drive. The remote keypad must be
operational in order for the STOP key to be active.
5. SETTING UP THE SM-PLUS DRIVE
There are three possible control scenarios when using the remote keypad:
1. The remote keypad is used for Start/Stop control, Forward/Reverse
selection, programming, and monitoring.
2. The remote keypad is used for programming and monitoring, but the
drive’s terminal strip is used for Start/Stop control and Forward/Reverse
selection.
3. The remote keypad is used for programming and monitoring, while
Start/Stop control and Forward/Reverse selection can be toggled
between the remote keypad and the drive’s terminal strip.
In all of the above scenarios, speed is controlled from the remote keypad
unless another speed reference source is selected.
NOTE 1: The STOP key on the remote keypad will work even if the
terminal strip is used for Start/Stop control.
1. REMOTE KEYPAD TO PROGRAM, MONITOR AND
CONTROL
a. Set Parameter 14 (CONTROL) to “02” (REMOTE KEYPAD
ONLY).
b. Install a jumper between terminal TB-1 and TB-2 on the drive’s
terminal strip.
2 . REMOTE KEYPAD TO PROGRAM AND MONITOR, AND
TERMINAL STRIP TO CONTROL.
a. Set Parameter 14 (CONTROL) to “03” (TERMINAL STRIP OR
REMOTE KEYPAD).
b. Wire the Start/Stop and Forward/Reverse circuits to the drive’s
terminal strip according to the SM-Plus manual.
3. TOGGLE CONTROL BETWEEN REMOTE KEYPAD AND
TERMINAL STRIP
a. Set Parameter 14 (CONTROL) to “03” (TERMINAL STRIP OR
REMOTE KEYPAD).
b. Choose either Terminal 13A or 13C on the drive as the input that
will toggle between remote keypad control and terminal strip control.
To use TB-13A, set Parameter 10 (TB-13A FUNCTION SELECT) to
“08” (REMOTE KEYPAD).
To use TB-13C, set Parameter 12 (TB-13C FUNCTION SELECT) to
“07” (REMOTE KEYPAD).
c. Wire a selector switch or relay contact between TB-13A or TB-13C
(whichever was programmed for REMOTE KEYPAD in Step b
above) and TB-2 on the drive’s terminal strip.
d. Wire the Start/Stop and Forward/Reverse circuits to the drive’s
terminal strip according to the SM-Plus manual.
NOTE: If a 2-wire Start/Stop circuit is required, use the Alternate 2-
Wire circuit described in Section 11.3 of the SM-Plus manual.
To select the Remote Keypad as the control source, close TB-13A or TB-
13C (whichever was programmed for REMOTE KEYPAD) to TB-2.
To select the terminal strip as the control source, open TB-13A or TB-13C
with respect to TB-2.
NOTE 2: When the remote keypad is selected for Start/Stop control,
terminal TB-1 on the SM-Plus drive must be closed to TB-2 to allow the
drive to run. TB-1 is a Stop input and it is always active. If it is open with
respect to TB-2, the drive will not run.
STOP
RUN
CONDITION / DISPLAY POSSIBLE CAUSES
Remote Keypad display
is blank. Parameter 14 - CONTROL is set to “01”
(TERMINAL STRIP ONLY)
The Remote Keypad is not wired correctly to the
drive.
Remote Keypad
and/or SM-Plus
drive displays “JF” JF is a serial fault, which indicates a communi-
cation problem. Check for proper wiring between
the remote keypad and the drive.
A “JF” fault will also occur if an attempt is made
to power the remote keypad and an ausiliary
relay from TB-11. See Note 2 in Section 4.
The RUN key does not
work to start the drive. To start the drive using the RUN key, the
Remote Keypad must be selected as teh control
source, and TB-1 must be closed to TB-2 on the
drive’s terminal strip. Refer to Sections 4 and
5.relay from TB-11. See Note 2 in Section 4.
The R/F key does not
work to change rotation
direction. To use the R/F key to change rotation direction,
the remote keypad must be selected as the
control source, and Parameter 17 (ROTATION)
must be set to “02” (FORWARD AND
REVERSE). Refer to Sections 4 and 5.
