NOTICE
Do not misuse the holding brake as a working brake
because this causes increased wear, resulting in
premature failure.
NOTICE
Using servo drives with brakes can reduce the number of
drives allowed, depending on the total length of each
hybrid line. See the shell diagram in the

3.2.2.3 Cooling
The servo drives are self-cooling.
Cooling (heat dispersal) is primarily via the flange, with a
small amount dispersed by the housing.
3.2.2.4 Thermal Protection
Thermal sensors monitor the maximum allowable
temperature of the motor winding and switch the motor
off if the limit of 140 °C is exceeded. Thermal sensors are
also present in the drive to protect the electronics against
overtemperature. An error message is sent via Real-Time
Ethernet to the higher-level PLC and is also shown on the
LCP.
3.2.2.5 Built-In Feedback Devices
The built-in feedback device measures the rotor position.
There are 3 feedback variants available:
•
Resolver
•
17-Bit single-turn encoder
•
17-Bit multi-turn encoder
