Siemens SIMOTICS FD 1LL1, Operating Instructions & Installation Instructions

Page: 112 / 188

If you want to start the machine for a trial run, ensure that it is connected to the cooling water
supply.
WARNING
Risk of burning from hot steam
If the cooling water supply fails, the motor will overheat. If cooling water runs into the hot
machine, hot steam suddenly forms, which 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 you use the SINAMICS G120/G150 or
SINAMICS S120/S150 converter, you can set the motor parameters via STARTER or the
"Advanced Operating Panel" AOP30.
If you use the SINAMICS G120P inverter, you can set the motor parameters via the "Intelligent
Operator Panel" (IOP).
NOTICE
Undesirable operating states
If the incorrect motor type has been selected, then this can result in undesirable operating
states, for instance increased noise.
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.
