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 safety category are the drive safety functions rated to?

SIL2, Cat.3/PL d

How can I review the previous alarms that are not currently active on a drive?

Go to “Drive” > ”Diagnostics” > ”Alarms history”

What is the difference between OFF1, OFF2 and OFF3?

OFF enables are the three main enables that exist in the drive. By individually removing them they are differentiated in the following way: 

  •  OFF1 – Speed setpoint = 0 and the drive brakes the motor along the configured deceleration ramp (p1121). 
  • OFF2 – Pulses are immediately supressed and motor will coast to a stop. If there is a holding brake, then this will be engaged straight away. 
  • OFF3 – Speed setpoint = 0 and drive is braked along the OFF3 ramp (p1135).

What safety category are the drive safety functions rated to?

SIL2, Cat.3/PL d

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. 

I have a flashing green COM light on my Control Unit. What does this mean?

Communication from a master device is partially or yet to be fully established. Therefore, cyclic communication is not possible.
