● If you want to start the machine for a trial run, ensure that it is connected to the cooling water
supply.
WARNING
Risk of burns from hot steam
If the cooling water supply fails, the motor will overheat. If cooling water enters the hot
cooling water tubes, hot steam will suddenly be generated, which then escapes under high
pressure. The cooling water system can burst. This can result in death, serious injury or
material damage.
● Do not connect the cooling water supply until the machine has cooled down.
7.9 Switching off
● If the controller does not do this automatically, switch on any anti-condensation heating
during stoppages. This will avoid the formation of condensation.
● Do not switch on the anti-condensation heating for at least two hours after the motor has
been switched off. This prevents damage to the winding insulation.
7.10 Setting the motor parameters at the converter
The selection of the motor type is used to pre-assign specific motor parameters and to optimize
the operating characteristics and behavior. If the incorrect motor type has been selected, then
this can result in undesirable operating states, for instance increased noise.
● If you use the SINAMICS G120/G150 or SINAMICS S120/S150 converter, you can set the
motor parameters using STARTER or the "Advanced Operating Panel" AOP30.
● If you use the SINAMICS G120P converter, you can set the motor parameters using the
"Intelligent Operator Panel" (IOP).
Note
Preset space-vector modulation for SINAMICS S converters
Unlike SINAMICS G converters, space-vector modulation is preset for SINAMICS S
converters. Provided permitted by the application, the space-vector modulation can be
changed manually to an optimized pulse pattern for SIMOTICS FD motors.
The SINAMICS parameter is p1802 = 19 in the STARTER and in the AOP30.
