Description
You can make a request to know the object status.
Perform start/stop and simple frequency setting.
Perform frequency setting in 0.005% increments.
Execute functions assigned to the inverter input terminals.
You can select either of RAM or EEPROM as the write
destination of set frequencies.
You can set the set frequency in 0.1/0.01Hz or 0.005% increments.
You can reset the inverter at an inverter alarm occurrence.
You can make an emergency stop of the inverter.
Input the set point for PID control.
Input the current measured value for PID control.
Input the current deviation for PID control.
Input a code to select a monitor type.
You can make command requests, e.g. operation mode
selection, parameter write, inverter reset, to the inverter.
You can set the time from when the inverter starts until when
data is sent to the network.
Used to prevent rotation in the wrong direction.
You can set the reference frequency of set frequency
(nviInvSetFreqP) and output frequency (nvoInvOutFreqP).
Set the maximum frequency of the inverter.
Set the minimum frequency of the inverter.
