Parameterization of the axis characteristic
The axial course of the acceleration characteristic must be parameterized using the following
machine data:
Number MD Identifier Default Value
linear circular
32000
MA_MAX_AX_VELO 10,000.0
mm/min
27.7
r.p.m.
32300
MA_MAX_AX_ACCEL 1 m/s
2
2.77
rev’s/s
2
35220 MA_ACCEL_REDUCTION_SPEED_POINT 1
35230 MA_ACCEL_REDUCTION_FACTOR 0
* : The selection of the value depends on the motor characteristic.

Service display of the axis drive behavior
SINUMERIK 802S provides two possibilities to evaluate the axis drive behavor:
Servo Trace
To provide axis service, the Servo Trace function is integrated in the Diagnosis menu, which
can be used for graphical representation of the axis setpoint speed.
