Santerno Sinus Penta - List of Parameters C285 to C294

PROGRAMMING GUIDE
SINUS PENTA
397/486
In Two PIDs mode:
if C171a = 0: Disabled, the PID output is summed with the PID2 output;
if C171a is enabled, the logic state of the configured input determines which is the output of the PID regulator to be
used: 0 → PID, 1→ PID2.
In 2-zone mode:
if C171a is enabled, when the selected input is activated, the 2-zone mode (MIN or MAX) is disabled. In that case, the
PID regulator always operates on the error resulting from C285–C288 and with parameters P2xx.
The PID regulator output may be used as:
• an external output;
• a speed/torque reference of the drive;
• a speed/torque reference increase or, if the IFD control is used, the PID regulator input may be used for
correcting the output voltage.
If the PID regulator output is the speed reference of the drive, the selected speed/torque ramp is applied.
SERIAL LINK
The Serial Link source is an input from the MODBUS link: the reference value shall be written by the user to the
following addresses:
