Vibration severity and vibration severity grade A according to IEC 60034‑14

The vibration severity is the RMS value of the vibration velocity (frequency range from 10 Hz to 1000 Hz). The vibration severity is measured using electrical measuring devices according to DIN 45666.

The specified values refer only to the motor. These values can increase as a result of the overall system vibrational behavior due to installation.

Vibration severity limit values

The speeds of 1800 rpm and 3600 rpm and the associated limit values are specified according to IEC 60034‑14.
The speeds of 4500 rpm and 6000 rpm and the specified values are defined by the motor manufacturer.

The motors maintain vibration severity grade A up to the rated speed.

Balancing according to ISO 21940‑32

Apart from the balance quality of the motor, the vibrational quality of motors with attached belt pulleys is mainly determined by the balance state of the mounted component. If the motor and the mounted component are balanced separately before being joined, the balancing process of the belt pulley is to be adapted to the motor's balancing type.

SIMOTICS S‑1FS2 motors with feather key are always half-key balanced. In general, motors with a plain shaft are recommended for systems with the most stringent vibrational quality requirements.

Vibration stress, immitted vibration values

The requirements of environmental class 3M8 (according to EN 60721‑3‑3 Table 6) must be maintained for proper function and saferd the bearing life. The following limits are valid for (immitted) vibration values introduced into the motor from outside:

Vibration velocity Vrms according to ISO 10816, max. 4.5 mm/s (0.18 in/s)

Vibration acceleration apeak axial and radial 50 m/s2 (164 ft/s2)

During transport, the motors withstand single shocks (6 ms) of up to 250 m/s2 (820 ft/s2).

Ambient temperature and installation altitude

Operating range without restrictions:

Temperature range from -15 °C to +40 °C (5 °F to 104 °F), installation altitude up to 1000 m (3281 ft).

If deviating conditions are encountered, the S1 characteristic of the motor must be adapted with regard to speed and torque.

Use the following equation to calculate the reduced S1 characteristic:
S1red (n) = xD × S140 °C (104 °F); 1000 m (3281 ft) (n/xD)

Encoder system

In motors with integrated OCC/DRIVE-CLiQ interface, the sensor ** is already digitally prepared in the motor, and then transferred quickly and without loss to the drive system. Motors with an OCC/DRIVE-CLiQ interface simplify commissioning and diagnostics, as the motor parameters and encoder system are identified automatically.

Multiturn absolute encoder:

AM22DQC: Absolute encoder 22-bit + 12-bit multiturn

This encoder outputs an absolute angular position between 0° and 360° in the specified resolution. It can also count 4096 revolutions. The absolute position is also sensed in the de-energized state. So with a ball screw, for example, the absolute position of the slide can be determined over a longer distance.

Holding brake

Many drives need a holding brake with an EMERGENCY STOP function for safety reasons or to meet process requirements. The brakes used on SIMOTICS S-1FS2 motors operate on the quiescent current principle. A spring or permanent magnet exerts a tensile force on the brake armature disk, i.e. in a state of zero current, the brake is closed and the motor shaft thereby stopped.

An electric current that flows through a coil generates an opposing field that counteracts the force effect of the spring or permanent magnet and releases or holds open the brake. Only a limited number of braking operations can be performed for an EMERGENCY STOP or power failure without causing excessive wear on the holding brake. The holding brake is not an operational brake. Regular dynamic braking leads to increased wear and premature brake failure. In order to ensure the functionality and specification of the brake, neither the total operating energy nor the maximum switching energy per braking operation may be exceeded.

The brake control is already fully integrated into the SINAMICS S210 converter system, so that an external circuit is not necessary.

After an EMERGENCY STOP sequence with the maximum single switching energy, a cooling time of at least 5 minutes is required.

The following table contains technical specifications of the holding brakes for operating on a SINAMICS S210.

1) Typical values at an ambient temperature of 20 °C (68 °F). At -15 °C (5 °F), the break-induced currents can increase by up to 30 %.
