Overview of Alarms

SINAMICS-Alarms

The limit value for the function "Safely-Limited Speed" (SLS) is greater than the speed that corre-

sponds to an encoder limit frequency of 500 kHz.

This fault does not result in a safety stop response.

Fault value (r0949, interpret decimal):

Maximum permissible speed.

Correct the limit values for SLS and carry out a POWER ON.

SI: Safety Integrated

SLS: Safely-Limited Speed / SG: Safely reduced speed

Acknowledge:

IMMEDIATELY (POWER ON)

At least one enabled "Safety Cam" (SCA) is parameterized in p9536 or p9537 too close to the toler-

ance range around the modulo position.

The following conditions must be complied with to assign cams to a cam track:

- the cam length of cam x = p9536[x]-p9537[x] must be greater or equal to the cam tolerance + the

position tolerance (= p9540 + p9542). This also means that for cams on a cam track, the minus posi-

tion value must be less than the plus position value.

- the distance between 2 cams x and y (minus position value[y] - plus position value[x] = p9537[y] -

p9536[x]) on a cam track must be greater than or equal to the cam tolerance + position tolerance (=

p9540 + p9542).

This fault does not result in a safety stop response.

Fault value (r0949, interpret decimal):

Number of the "Safe Cam" with an illegal position.

See also: p9501 (SI Motion enable safety functions (Control Unit))

Correct the cam position and carry out a POWER ON.
