Variable: nviDrvSpeedStpt
Format: SNVT_switch
Explanation:
This network variable input provides a speed reference setpoint. When
nviDrvSpeedStpt.state is set to zero, the drive is stopped.
Valid Range:
Default Value:
Default value is AUTO (state = 0xFF). This value is adapted at power up.
This network variable input uses adapter Parameter 7 - [RcvHrtBeat
Time] if this function is set up for use. The actual drive speed also depends
on nviDrvSpeedScale.
Variable: nviDrvSpeedScale
Format: SNVT_lev_percent
Explanation:
This network variable input provides scaling for nviDrvSpdStpt. For
example, if nviDrvSpeedStpt value is 100% and nviDrvSpeedScale value is
-150%, then actual speed setpoint value is -150% (reverse direction at 1.5
times nominal speed).
Valid Range: -163.84…163.83%
Default Value: Defined by nciDrvSpeedScale.
