This section describes the basic functions of the front panel keys.
This is a programmable function key. When it is pressed for at least 1 second,
the function set in the PF Setting parameter will operate.
Example for When the PF Setting Parameter Is Set to R-R (Default: R-R):
With this setting, the PF Key operates as a Reverse Run/reset Key to switch
between run status and reset status.
The status changes from reset to run status when the key is pressed for at
least one second and changes from run to reset status when the key is
pressed for at least two seconds.
Press this key to move between setting levels. The level is selected in the fol-
lowing order: operation level, program setting level, adjustment level, PID set-
ting level, and then operation level. From initial setting level you can go to and
from communications setting level.
Press this key to change parameters within a setting level.
The parameters can be reversed by holding down the key (moving one per
second in reverse order).
Each press of this key increments the value displayed on the No. 2 display or
advances the setting. Holding the key down speeds up the incrementation.
Each press of this key decrements values displayed on the No. 2 display or
reverses the setting. Holding the key down speeds up the incrementation.
Press these keys to change to the protect level. For details on operations
involving holding these keys down simultaneously, refer to 1-3 Setting Level
Configuration and Key Operations. For details on the protect level, refer to
SECTION 5 Parameters.
To restrict set value changes (in order to prevent accidental or incorrect oper-
ations), these key operations require simultaneously pressing the O key
along with U or D key. This applies only to the parameter for the password to
move to protect level. (Refer to page 182.)
The function that is set for the PF Setting parameter will operate when the
Mode Key and Up Key are pressed at the same time for at least one second.
They perform the same function as the PF Key. If you are using the E5CN-HT,
use the M+U Keys whenever the manual says to use the PF Key.
