Power Drive Systems standard EN61800–3
The Drive meets the immunity requirements of EN61800–3 irrespective of
the environment in which it is operating.
The emission requirements of this standard are also met depending on the
environment category, as follows:
First environment: Restricted distribution only: specified RFI filter
required
Second environment: No RFI filter required (but RFI filter(s) are
recommended where sensitive electronic systems are operating
nearby); emission limits are under consideration
EN61800–3 defines the first environment as one that includes domestic
premises. It also includes establishments directly connected without
intermediate transformers to a low-voltage power supply network which
supplies buildings used for domestic purposes.
The second environment is one that includes all establishments other than
those directly connected to a low-voltage power supply network which
supplies buildings used for domestic purposes.
Restricted distribution is defined as a mode of sales distribution in which the
manufacturer restricts the supply of equipment to suppliers, customers or
users who separately or jointly have technical competence in the EMC
requirements of the application of Drives.
Note
If a Power Drive System is included as part of equipment
covered by a separate EMC product standard, the EMC
standard for the complete equipment applies.
Frequencies
AC supply frequency: 50Hz to 60Hz ±2Hz
PWM switching frequency: 3kHz nominal (selectable up to 12kHz)
Maximum output frequency: 240Hz (up to 960Hz)
For operation at PWM switching frequencies above 3kHz, refer to the
Dinverter A Technical Reference Manual.
Accuracy
and
resolution
The following data applies to the Drive only; it does not include the
performance of the source of the control signals.
Output frequency accuracy: ±0.01%
Output frequency resolution:
0.001Hz up to 480Hz
0.002Hz from 480Hz to 960Hz
Output voltage accuracy: depends on
AC supply stability
Output voltage resolution: 0.4%
Tracking-accuracy of output current to changes in load:
±10% above 20Hz (with a motor matched to the Drive)
Tracking-resolution of output current to changes in load: 0.1%
