Operation for Setting
· To select the parameter setting displayed as the initial value, press the Down arrow
key to move to the next parameter.
· To change and set the parameter setting, press the SET/ENTER key to start the set-
point blinking. The blinking state allows you to make changes (setting mode). Use the
Up/Down/Left/Right arrow keys to change the setpoint. Press the SET/ENTER key to
register the setting.
Note that there are some parameters which are not displayed depending on the model and suffix
codes, control mode (CTLM), control type (CNT), etc. The parameters for professional setting
mode (LEVL: PRO) are not described in this manual. See User’s Manual (IM 05P01C31-01EN).
