Dithering frequency
This value is calculated from the configured period duration of the dither signal.
The value cannot be changed (read only).
Current control
You can use this parameter to activate the PID algorithm for the control of the output current.
The parameter is disabled in the default setting.
Note
High-speed output
You can use current control with the associated parameters only in "Pulse width modulation
PWM" mode with deactivated "High-speed output (0.1 A)".
Enable proportional action
You can use this parameter to activate the proportional action of the PID algorithm.
The parameter is enabled in the default setting.
Enable integral action
You can use this parameter to activate the integral action of the PID algorithm.
The parameter is enabled in the default setting.
Enable derivative action
You can use this parameter to activate the derivative action of the PID algorithm.
The parameter is disabled in the default setting.
Reference value current
You use this parameter to specify the maximum current as reference value for the current
setpoint. A value of 100% for OUTPUT_VALUE in the control interface corresponds to a
current setpoint in the magnitude of the reference value of the current.
The recommended setting is the value of the load current that is measured when current
control is deactivated and the duty cycle is 100%.
The default setting is "0 mA".
