M-Max Series Adjustable Frequency Drive

Operational Data Indicator, continued
Under the system parameters S3.1 to S4.1 (see “System Parameter” on
Page 125
) you can
also display the operational data of the M-Max frequency inverter and adjust the contrast of
the display unit.
Example of Status Displays
The status displays of the digital inputs and outputs are equivalent. These make it possible to
check for whether an output control signal (for example, from an external controller) of the
inputs (DI1 to DI6) activates the frequency inverter. This provides you with a simple means for
checking the wiring (wire breakage).
The following table shows a few examples.
Display value:
●
1 = activated = High
●
0 = not activated = Low
