Note1: The PID number (1 to 8, R) is displayed on Group display while the parameter SP, SUB,
HYS, SU.HY, DR, or SU.DR is displayed.
Note
When changing the setpoint of the parameter PIDG., if the setpoint of the parameter PIDN
which belongs to the SP menu is larger than that of the parameter PIDG., the PIDN setpoint is
changed to the PIDG. setpoint.
