Local/Remote key function [217]
The Toggle key on the keyboard, see section 10.2.8, page
89, has two functions and is activated in this menu. As
default the key is just set to operate as a Toggle key that
moves you easily through the menus in the toggle loop. The
second function of the key allows you to easily swap between
Local and normal operation (set up via [214] and [215]) of
the AC drive. Local mode can also be activated via a digital
input. If both [2171] and [2172] is set to Standard, the
function is disabled.
Lock Code? [218]
To prevent the keyboard being used or to change the setup
of the AC drive and/or process control, the keyboard can be
locked with a password. This menu, “Lock Code [218]”, is
used to lock and unlock the keyboard. Enter the password
“291” to lock/unlock the keyboard operation. If the
keyboard is not locked (default) the selection “Lock Code?”
will appear. If the keyboard is already locked, the selection
“Unlock Code?” will appear.
When the keyboard is locked, parameters can be viewed but
not changed. The reference value can be changed and the
AC drive can be started, stopped and reversed if these
functions are set to be controlled from the keyboard.
Rotation [219]
Overall limitation of motor rotation
direction
This function limits the overall rotation, either to left or
right or both directions. This limit is prior to all other
selections, e.g.: if the rotation is limited to right, a Run-Left
command will be ignored. To define left and right rotation
we assume that the motor is connected U-U, V-V and W-W.
Speed Direction and Rotation
The speed direction can be controlled by:
• RunR/RunL commands on the control panel.
• RunR/RunL commands on the terminal strip
(terminals 1-22).
• Via the serial interface options.
• The parameter sets.
