PID Control Restart Frequency after
Stopping for Process Control (300EHex-12Hex)
PID Control Sleep Frequency for
Process Control (300EHex-10Hex)
• PID Control Restart Delay Time after Stopping for Process Control (300EHex-19Hex)
The inverter restarts when both of the following conditions are satisfied.
1. The discharge pressure falls, the frequency reference value of the PID controller output rises, PID
Control Restart Frequency after Stopping for Process Control (300EHex-12Hex) is exceeded, and
PID Control Restart Delay Time after Stopping for Process Control (300EHex-19Hex) elapses.
2. The difference between SV (command value) and PV (feedback value) becomes more than PID
Control Restart Feedback Deviation after Stopping for Process Control (300EHex-18Hex), and the
PID Control Restart Delay Time after Stopping for Process Control (300EHex-19Hex) elapses.
