NETWORK VARIABLES
6.6.3 PID deviation (network input SNVT_lev_percent nviInvPIDDev)
Input the set value of air volume, temperature, etc. in 0.005% increments.
⋅ Data acceptance timing........... At network variable receive (nv_update_occurs event)
For example, when the set point is 25°C and the current temperature is 30°C on a 10°C/0% and 50°C/
100% detector (deviation: +5°C),
As the PID deviation, input 12.50%.
Data Name Initial Value Range Increments
nviInvPIDDev 0.000% -100.00% to +100.00% 0.005%/bit
REMARKS
• Control cannot be exercised at less than the minimum resolution (0.01%) of the inverter.
• When the value outside of the range is input, the input value is made invalid and the inverter operates with the value
set last time.
