Use the following screws and washers for flange assembly.
Motors with low rotor inertia (type code designation "0") are optimized for dy‐
namic applications with maximum acceleration capacity.
In the mean rotor inertia design (type code designation "1"), the motor is opti‐
mized for applications with increased requirements on controllability and syn‐
chronous operation.
The speed to the corresponding winding designations are standard values.
The specified rated speed can deviate from the specified in the technical data
sheet. The speed is determined to define the winding designation on which
the standstill torque on the voltage limit characteristic curve U
(tolerance range ca. ± 250 1/min).

The motor temperature is monitored by two systems that are operated inde‐
pendently of each other. The mounted temperature sensor and the drive-in‐
ternal temperature model ensure the best protection of motors against ther‐
mal overload.
The threshold values for motor temperature monitoring are contained in the
encoder data memory and are read in and monitored automatically during the
operation with IndraDrive controllers. Threshold values for MS2E motors:
●
Motor-warning temperature (125°C)
●
Motor-disconnection temperature (130°C)
