3 SPECIFICATIONS MELSEC-Q 3.2.1 Auto tuning function (1) What is the auto tuning function? (a) The auto tuning function is designed for the Q62HLC to set the optimum PID constants automatically. In auto tuning, a manipulated value turns ON/OFF and the PID constants are calculated according to the hunting cycle and amplitude, which take place when the measured value to a set value alternates between overshooting and undershooting.
Page 39 3 SPECIFICATIONS MELSEC-Q (2) Executing auto tuning Conditions for starting auto tuning When any of the following conditions is met, auto tuning is not executable. In the Unused channel setting (buffer memory address: 61, 93), 1 (Unused) is set for the channel. The control mode switching (buffer memory address: 50, 82) is set in any of manual control mode 1, manual control mode 2 or program control mode.
Page 40 3 SPECIFICATIONS MELSEC-Q Auto tuning operation Auto tuning performs operation as shown below. Auto tuning output is provided. Data collection starts when the process value returns to the set value after the first overshoot and undershoot. After data collection, auto tuning ends when PID constants and loop disconnection detection judgment time are set.

AT differential gap and AT additional lag can be optionally set within the setting range.
Page 44: Reverse/Forward Action Select Function

The execution of the loop disconnection detection is performed with the setting of loop disconnection detection judgment time (buffer memory address: 59, 91).
Page 47: Data Storage On Feram Function
3 SPECIFICATIONS MELSEC-Q POINT (1) When not using the loop disconnection detection function, set the loop disconnection detection judgment time (buffer memory address: 59, 91) to "0". (2) Setting the loop disconnection detection dead band will not cause a loop disconnection if there is no temperature variation of 2 or more when the control output is provided 100% or 0% at the set value.

It is used to turn on the device's hazard signal or operate the safety device. The alert function is classified as follows: •...
Page 50 3 SPECIFICATIONS MELSEC-Q 2) Lower limit deviation alert When the deviation [measured value (PV) - set value (SV)] is equal to or less than the alert set value, the system is put in an alert status. The setting range is full-scale. [When alert set value is positive] [When alert set value is negative] Measured value (PV)
Page 51 3 SPECIFICATIONS MELSEC-Q (2) The Q62HLC allows the alert function in (1) to be set with the addition of an alert dead band, alert delay count or wait/re-wait. The following table indicates the alert functions which can be used with the addition of alert dead band, alert delay count and wait/re-wait.
Page 52 3 SPECIFICATIONS MELSEC-Q (b) Alert delay count setting The system is set in the alert status when the process value (PV) that has reached the alert set value remains in the alert range until the sampling count becomes equal to or greater than the preset number of alert delays. The setting of alert delay count is made by the alert delay count (buffer memory address: 165).
Page 53 3 SPECIFICATIONS MELSEC-Q (c) Wait alert Choosing the wait alert ignores the alert status if the process value (PV)/deviation is in that status when the setting mode is changed to the operation mode, and makes the alert function invalid until the process value comes out of the alert status once.
Page 54: Control Output Setting At Cpu Stop Error Occurrence Function

Page 220: Precautions For Online Module Change
7 ONLINE MODULE CHANGE MELSEC-Q 7.4 Precautions for Online Module Change The following are the precautions for online module change. Always perform an online module change in the correct procedure. A failure to do so can cause a malfunction or failure. If you resume control after setting the prerecorded values to the buffer memory of the new module after an online module change, control cannot be resumed in the same control status since the manipulated values (MV) (buffer memory address:...
Page 221 7 ONLINE MODULE CHANGE MELSEC-Q (3) Data save After module change, the buffer memory returns to default value (value read from FeRAM). Saving and recovering the buffer memory contents is necessary to continue previous operating states in changed module. However, if recovery with sequence program or initial settings is possible, this operation is not necessary.
Page 222: Precautions After Module Change
7 ONLINE MODULE CHANGE MELSEC-Q 7.4.2 Precautions after module change (1) Data recovery Leaving from online module change mode once when changed module is normally recognized allows you to recover the data before resuming control. As direct device access (MOV Un\G*), FROM/TO instruction and auto refresh setting by sequence program are invalid at this moment, perform data recovery with test operation of GX Developer or GX Configurator-TC manually.
