8. 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 “02” (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.
RUN key: Press RUN to Start the drive. TB-1 must be closed to
TB-11. See the wiring diagram in Section 4
WARNING!
If the remote keypad display is totally blank or only the decimal points are lit,
or it 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 DRIVE
To set up the SM drive to work with the Remote Keypad, the following
parameters must be programmed:
P11 TB-13B FUNCTION Set to REMOTE KEYPAD (13)
P12 TB-13E FUNCTION Set to REMOTE KEYPAD (21)
P14 CONTROL Set to REMOTE KEYPAD ONLY (02).
When this is done, and the Remote Keypad is connected, only the Remote
Keypad can start the drive and select direction. This results in some functions
of the drive being unavailable. These are explained below:
1. The Dynamic Braking option cannot be used because TB-13E is required
for the Remote Keypad.
2. Settings 05, 06, and 07 on TB-13A (Parameter 10) are disabled. These
settings are related to direction control. Only the Remote Keypad can be
used for direction commands.
Refer to the SM Installation and Operation Manual for more information.
NOTE: Once the drive is set up for Remote Keypad control, the buttons on
the front of the drive are disabled. If they are pressed, the drive display and
Remote Keypad display will show “SE”, indicating that the buttons are disabled.
STOP
RUN
7. REMOTE KEYPAD DISPLAY
The SM Remote Keypad has a three digit display like the SM drive.
The displays below are examples of the drive in RUN mode. On the left, the
drive is running at 43.6 Hz. On the right, the speed has been changed to 52.8
Hz (during speed command changes, the upper left decimal point turns on).
The displays below are examples of problems that will occur if the drive is not
properly programmed or if the keypad is not wired properly to the drive.
Make sure Parameters 11,
12, and 14 are properly
set. Make sure the keypad is
properly wired to the
drive and the cable is
away from noise.
POSSIBLE CAUSES
Remote Keypad display
is blank, or only the
decimal points are
illuminated. Parameter 14 - CONTROL is set to “01”
(TERMINAL STRIP ONLY)
Parameter 11 - TB-13B is not set to “13”.
Parameter 12 - TB-13E is not set to “21”.
The Remote Keypad is not wired correctly to the
drive.
Remote Keypad and/or
SM 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 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.
