5.2.2 Rated currents
The maximum permissible drive output current and the peak current are dependent on the power
stage switching frequency, the drive type and the ambient temperature.
All the specifications below are given for an ambient temperature from +5°C (41°F) to +40°C (104°F).

Table 10: Rated and peak output current. Peak current maximum 12s. The drive continuously calculates a thermal
model (i^2*t) for the three motor phases and for the three drive phases and switches off before damage can occur.
Overload protection on the supply side: The TPxxx power supply hardware manual demands a three phase input
current protection of 20A and a maximum prospective current rating of 40 kArms. Equivalent protection must be
provided if a third party power supply is used.
5.2.3 EMC and Motor properties
There are restrictions on the motor and motor cable properties depending on the PWM frequency. In
the following table, capacity refers to the sum of cable capacity and motor capacity with respect to
earth.

Table 11: Permissible motor and motor cable properties.
The Hardware Manual of the power supplies (TP80 and TP130) contain
Further restrictions on the total permissible capacity of all motors and motor cables attached to the
same power supply.
The expected EMC class according to the standard EN 61800-3 depending on these properties.
To reach these EMC requirements, proper shielding is mandatory, see chapter 7.2. Some motor proper-
ties might require a motor-side sine filter.
If a third party power supply is used, be aware that
The EMC level reached depends strongly on the common mode filter capability of the power supply.
The complete system must be tested for conformance with 61800-3, especially the conducted emis-
sions part.
Input protection circuitry must protect the Dc-Bus from external Burst and Surge events.
