Vibration

tested in accordance with DIN/IEC 68/EN 60068

part 2-6;

0.15 mm path with 10 … 58 Hz;

2 g acceleration with 58 … 150 Hz

Shock

tested in accordance with DIN/IEC 68/EN 60068

parts 2-27;

±15 g at 11 ms duration; 5 shocks per direction

1)

With constant travel profile. The specifications apply only when the motor is directly mounted. If a gearbox is also installed, the

repeat accuracy will be different.

2)

Dependent on the encoder resolution

3)

Output torque less friction is dependent on speed.

4)

At maximum rotational speed

5)

Cylinder-dependent;  values with DSBC-32/40 (with ESBF-32/40, these values must be the limit)

6)

Horizontal use (for vertical use and symmetric, not-eccentric configuration up to 15 kg are possible)
