(c) Enablement of setting contents
Enable the setting contents by turning Setting change instruction (YnB) OFF ON OFF during the setting
mode (Setting/operation mode status (Xn1): OFF).
When the set value is out of the range, a write data error (error code: 4
H
) occurs, and the Q64TCN
operates with the previous set value. Turning Setting change instruction (YnB) OFF ON OFF after the
error occurrence and setting a value within the range operate the Q64TCN with the new set value.
(d) Default value
The default values are set to 0 in all channels.
(53)CT Heater current process value (Un\G256 to Un\G263)
The heater current value which Q64TCTTBWN or Q64TCRTBWN detects is stored in this buffer memory area.
Values to be stored vary depending on the setting of CT CT selection (Un\G272 to Un\G279). ( Page 140,
Section 3.4.2 (55)
•Q64TCTTBWN
•Q64TCRTBWN
To perform the measurement of the heater current, the following buffer memory areas need to be set.
•CT CT input channel assignment setting (Un\G264 to Un\G271) ( Page 139, Section 3.4.2 (54))
•CT Reference heater current value (Un\G280 to Un\G287) ( Page 141, Section 3.4.2 (56))
If the both are set to 0, the heater current cannot be measured. If either of them is not set, the heater current cannot be
measured precisely.
