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
P12
TB-13E FUNCTION
P14
CONTROL
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 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
The SCL/SCM Remote Keypad has a three digit display like the
SCL/SCM 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.
Set to REMOTE KEYPAD (13)
Set to REMOTE KEYPAD (21)
Set to REMOTE KEYPAD ONLY (02).
Make sure the keypad
is properly wired to the
drive and the cable is
away from noise.
