REMOTE KEYPAD FUNCTIONS

The

M key and the s and t keys on the remote keypad function the

same as the

Mode button and the s and t 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.

SETTING UP THE SCF 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 SCF 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 SCF manual.

If a 2-wire Start/Stop circuit is required, use the Alternate 2- Wire
circuit described in Section 11.3 of the SCF 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 SCF 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.

TROUBLESHOOTING

CONDITION / DISPLAY

POSSIBLE CAUSES

Remote Keypad display
is blank.

Parameter 14 - CONTROL is set to “01”
(TERMINAL STRIP ONLY). See Section 5.
The Remote Keypad is not wired correctly
to the drive. See Section 4.

Remote Keypad and/
or SCF drive displays
“JF”.

“JF” typically indicates a communication
problem. Check for proper wiring between
the remote keypad and the drive. A “JF”
fault can also occur due of the following:
- Attempting to start the drive from the

Remote Keypad and TB-1 is not closed to
TB-2. See NOTE 2 in Section 5

- Attempting to power the Remote Keypad

and an auxiliary 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 the
control source, and TB-1 must be closed to
TB-2 on the drive’s terminal strip.

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, Parameter
17 - ROTATION must be set to “02”
(FORWARD AND REVERSE), and the

key must be pressed with 4 seconds to
confirm the change. See Section 6.

WARNING!
If the remote keypad display is totally blank or is displaying a “JF” fault,
