4.13 Complying with speed-torque curve
Risk of explosion if the speed-torque characteristic is exceeded
If the load torque exceeds the speed-torque characteristic, then the temperature class can be
exceeded. An explosion can occur. This can result in death, serious injury or material damage.
● It is not permissible that the values defined by the speed-torque characteristic are exceeded.
● Observe the data on the extra rating plate on the motor.
4.14 Voltage and frequency fluctuations during line operation
Unless otherwise stated on the rating plate, the permissible voltage/frequency fluctuation is
corresponds to Zone B in IEC / EN 60034‑1. Permissible fluctuations that go beyond this are
indicated on the rating plate.
Operate the machine in continuous operation in Zone A. Prolonged operation in Zone B is not
recommended:
● Exceeding the permissible tolerances for voltage and frequency can lead to an
impermissibly high temperature rise of the winding. This can result in long-term damage to
the winding.
● Limit exceptions of this sort with regard to the values that arise, how often, and for how long
they occur.
● Where possible and within a reasonable time take corrective actions such as reducing the
power. In this way you can avoid that the service life of the machine is reduced as a result
of thermal aging.
4.15 Phase synchronization during supply system switching
Damage to the machine may be caused when switching to another supply system with different
phasing.
● The phasing must be synchronized during switching. Use appropriate means to
synchronize the phasing.
4.16 System-inherent frequencies
Excessively high vibration levels and system resonances can damage the machine set.
● Configure and match the system consisting of the foundation and machine set in such a way
that no system resonances can arise and result in the permissible vibration levels being
exceeded.
● The vibration values according to DIN ISO 10816-3 must not be exceeded.
