SAMI G S 7.4 Adjusting Display Contrast The contrast of the LCD can be adjusted for optimal viewing. This can be done when the display is at Main or Group level. To adjust contrast, hold down and press or . It may be necessary to adjust the display contrast if the SAMI has been installed in a location with high ambient temperatures. The factory default setting is optimum for an ambient temperature between 15 o C and 30 o C. Running data and keypad control parameters A complete description of the parameter Groups is given in chapter 9, Drive parameters. Operating Data parameters are described here. 7.5 Operating Data The monitored values are updated five times a second.
The accuracy figures given in brack- ets are valid for steady state signals. Actual reference signal is shown once a second if the frequency converter is stopped. Note! If measured value goes beyond the range of the parameter, expression marks ("!!") are shown on the display. * ) This parameter indicates small current value even though the motor cables and the motor is not connected.
