CHAPTER 5 LONWORKS COMMUNICATION FUNCTION
11
Example (2) : nviInvSetFreq = 0 to 400
When nviInvSetFreq is at 60Hz and nviDrvSpeedScale is 100%, the inverter is in forward run at 60Hz.
Valid Range: -163.84 to163.83%
Default Value: Is defined by nciDrvSpeedScale (Refer to 5.4.14).
Scaling: See chapter 6.1.4
5.2.5 Emergency Override (SNVT_hvac_emerg nviEmergOverride)
When EMERG_SHUTDOWN command is inputted, the inverter executes the deceleration stop and also the
value in EMERG_SHUTDOWN is supported but the other values are not supported.
(Deceleration time is dependant on Ramp Down Time (Refer to chapter 5.4.10))
