Above is the table of parameters relevant to the KTY84 thermal protection function. Set Pn-740 as 1 to enable the
function, then the system will trigger the overheat alarm AL-200 if the measured temperature exceeds the level set
in Pn-741.
To enable thermal protection for Syntec encoders, simply set the thermal protection level to a value within the
range 0~145
℃
. If this level is already factory-set, it cannot be modified.
There are two ways to disable the thermal protection function, as follows:
For drives before V2.1.8, set the thermal protection level to 0.
For V2.1.8 and onward, use the parameter "Disable Encoder Int. Thermal Protection".
Example: Set Pn-742 "Encoder Int. KTY84 Protection Lv." as 140
℃
. To disable the protection, set Pn-74A "Disable
Encoder Int. Thermal Protection" as 1.
If the temperature exceeds the protection level, a corresponding overheat alarm will be triggered as follows:
