Simplicity on the Worksite Solutions Guide for FAQs: E5CC/E5EC Using PID Control You set this parameter in the Initial Setting Level. The parameter is set to ON/OFF control by default. Turn ON the power supply. 1 2 Press the K ey for at least 3 seconds. Initial Setting Level ← Flashes 3 times. Press the (Level) Key for at least 3 seconds. ← in-t (IN-T) will be displayed to show that the Initial Setting Level has been entered. Using PID Control Change the parameter with the Key . 3 Initial Setting Level ← cntl (CNTL): Indicates the Control Method parameter. ← Default setting is onof (ONOF): ON/OFF control Press the ( Mode) Key several times to display cntl (CNTL).
If onof (ON/OFF control) is displayed, press the ( Up) Key to change to pid (PID) (PID control). * cp (CP): Default setting of control period is 20 seconds for a relay output (R) and 2 seconds for a voltage pulse output (Q). Change the parameter with the Key . 4 Initial Setting Level ← st (ST): Indicates the Self-tuning parameter. ← Default setting is on (ON): Enabled. Change the set value with the (Up and Down) Keys. off (OFF): on (ON): Self-tuning disabled. Use this setting to perform autotuning or to set the PID constants manually. Self-tuning enabled. Use this setting to perform You cannot set the following parameters while self-tuning (ST) is enabled. • Adjustment Level:
MV Upper Limit, MV Lower Limit, SP Ramp Set Value, and SP Ramp Fall Value • Advanced Function Setting Level: SP Ramp Time Unit * To set these parameters, first set the st (ST) (self-tuning) parameter in the Initial Setting Level to off (OFF) to disable self-tuning. self-tuning (Refer to on page 3-1.) 2.
