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:
Alarm Alarm Name
Alarm 220 Motor Over Temperature
Alarm 320 Encoder Internal Over Temperature
Alarm 321 Encoder External(1) KTY84 Over Temperature
Alarm 322 Encoder External(2) KTY84 Over Temperature
Alarm 324 2nd Encoder Internal Over Temperature
Alarm 325 2nd Encoder External(1) KTY84 Over Temperature
Alarm 326 2nd Encoder External(2) KTY84 Over Temperature
For diagnosis and troubleshooting of overheat alarms, refer to the table below:

Check if the analog temperature
feedback is fine 1. Check if the wiring is loose or
abnormal
2. Check if the parameters Pn-740,
Pn-741 are correct
