7.6.3 Functions
Use this submenu to set the parameters for different functions. The parameters are divided into groups according to the functions.
7.6.4 Protections
Use this submenu to set the parameters for different protection functions. The parameters are divided into groups according to the
protection functions.
7.6.5 PID Setup
Use this submenu to set the PID parameters.
Analog Input Range: The range of the sensor.
l
Proportional Gain (Kp): The magnified proportional value of the SV-PV error.
l
Unit: %
¢
Set range: 0–30000
¢
Integral Gain (Ki): The magnified proportional value of an accumulation of each sampling time unit times the error value.
l
Unit: %
¢
Set range: 0–30000
¢
Differential Gain (Kd): The magnified proportional value of an error variable of each sampling time unit.
l
Unit: %
¢
Set range: 0–30000
¢
Upper Limit: If the upper limit is 900 RPM, the PID output stays at 900 RPM when the adjusting output value is above 900 RPM.
l
Lower Limit: If the lower limit is 300 RPM, the PID output stays at 300 RPM when the adjusting output value is below 300 RPM.
l
Error Band: The error band value is equal to the SV-PV deviation. If the difference between SV and PV is smaller than the error band,
l
PID stops output and the drive maintains the current output speed.
PID Output: The display of the actual PID output results.
l
SV: The expected values of the user set.
l
PV: The real value of the system output.
