Protection against impermissibly high surface temperatures
Explosion-proof servomotors in categories 3D and 3GD ensure safe operation under
normal operating conditions. The servomotor must be switched off securely in the case
of overload to avoid the risk of impermissibly high surface temperatures.
NOTE ON EXPLOSION PROTECTION
The CMP servomotors come equipped with KTY temperature sensors. The tempera-
ture monitoring for the motors must be performed using the KTY temperature sensor
and the provided temperature model. Due to the high dynamics, this is the only way to
provide for an effective thermal protection.
This is why, during startup and after any changes to the inverter parameters, you must
check that the temperature model of the servo inverter is activated. This is the only way
for the drive to be switched off if an overtemperature is detected.
The motor may only be restarted after the fault that tripped the temperature sensor has
been eliminated.
