Drives FAQs
SINAMICS V90
What is the peak torque profile?
300% rated torque for 300ms in 10sec
Can a Motor Brake Cable be connected to a SINAMICS V90 directly?
The Motor Brake Cable can be attached directly to the 400V version of the V90. The 200 V version requires an external relay to connect the motor brake cable. The relay must be connected via the setpoint cable for the SINAMICS V90 pulse train version and via I/O cable for the SINAMICS V90 PROFINET version. I/O cable is necessary for the brake control of the SINAMICS V90 PROFINET 200 V version, and for applications requiring additional DI/DO in addition to PROFINET communication.
What's the maximum motor cable length?
For both power and signal motor cables, up to 20m sizes are available from Siemens. The maximum permissible length for custom cables is 30m.
SINAMICS G120
What safety category are the drive safety functions rated to?
SIL2, Cat.3/PL d
What could be causing a return value of 8090 for DPRD_DAT/DPWR_DAT?
The hardware ID may be incorrect on the LADDR input. The required ID is the one used by the telegram - not the ID of the drive. For Startdrive, this can be found in the device view by going to Properties > General > Telegram configuration > [device name] > Start address. For drives not configured with Startdive, this can be found in the device view byhighlighting the row of the telemgra in Device overview, then navigate to Properties > General > Hardware identifier.
How can I review the previous alarms that are not currently active on a drive?
Go to “Drive” > ”Diagnostics” > ”Alarms history”
SINAMICS S120
What safety category are the drive safety functions rated to?
SIL2, Cat.3/PL d
How can I test and document the safety configuration?
By using a a script, the Safety Acceptance Test and associated documents can be efficiently executed/recorded. The latest script is available at:
In an emergency stop state I disable my line module at the same time as the drives. Is this the best/safest way?
No. The line module should be disabled when all axes have stopped moving. This allows for the line module to regenerate any excess energy that is produced by the motors stopping. A typical example would be to use a delayed safety contact to disable the module after the SS1 delay time has expired.
