“C” Group: Intelligent Terminal Functions

Output Function Adjustment Parameters

The overload level parameter (C41)sets the motor current level at which the overload signal becomes true. The range of settings is from 0% to 200% of the rated current for the inverter. This function is for gener- ating an early warning logic output, without causing either a trip event or a restriction of the motor current (those effects are available on other functions).

Drive Parameters

 

 

The frequency arrival signal is intended to indicate when the inverter output has reached (arrived at) the target frequency. You can adjust the timing of the leading and trailing edges of the signal via two parameters specific to acceleration and deceleration ramps, C42 and C43.

The Error for the PID loop is the magni- tude (absolute value) of the difference between the Setpoint (desired value) and Process Variable (actual value). The PID output deviation signal (output terminal function option code 04) indicates when the error magnitude has exceeded a magni- tude you define.
