MKE Synchronous Servomotors
Electrical connection
Bosch Rexroth AG
R911414374, Edition 01
Connection thermo controller
The connection of the PTC resistors, for the
motor temperature evaluation, is shown in the
respective connection diagrams of the drive con-
trol units.
WARNING
Risk of explosion due to impermissible tempera-
ture increase in case of faulty temperature evalu-
ation!
The connections [1] and [2] of the PTC resistor
(triplet PTC thermistor) must be connected to
the temperature monitoring of the drive con-
troller!
The maximum permissible surface temperature
of the MKE motors is ≤
135
°C, which corre-
sponds to temperature class T4. The triplet ther-
mistors installed in the MKE motors, in conjunc-
tion with the evaluation circuits of the drive
controllers, ensure reliable and safe overtemper-
ature shutdown.
