SETTING UP THE SCL/SCM DRIVE
To set up the SCL/SCM 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. Th
is results in some functions of the drive
being unavailable. Th
ese are explained below:
1. Th
e 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. Th
ese settings
are related to direction control. Only the Remote Keypad can be used for
direction commands.
Refer to the SCL/SCM 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.

REMOTE KEYPAD DISPLAY
Th
e SCL/SCM Remote Keypad has a three digit display like the SCL/SCM drive.
Th
e 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).
Th
e 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.
