309 Pulsecoder temperature
[Data type] Byte-axis
[Unit of data] Degrees centigrade
[Valid data range] 0 to 255
The temperature of the PCB in the αi pulsecoder is displayed. When it reaches
100°C (about 85°C in an ambient temperature in the pulsecoder), the motor
overheat alarm is generated.
Note
The temperature where the over heat alarm is generated has an error of
±5°C maximum.
403 1st spindle motor temperature
404 2nd spindle motor temperature
433 3rd spindle motor temperature
434 4th spindle motor temperature
[Data type] Byte
[Unit of data] Degrees centigrade
[Valid data range] 0 to 255
When αi spindle is used, the temperature of the αi spindle motor coil is
displayed. The temperature generating overheating is different in each motor.
The accuracy of temperature generating overheating has an error as follows.
… 160°C : ±5°C
160°C … 180°C : ±10°C
