Notes:
At travel speeds of more than 1,6 m/s and/or travel time of more than 30 seconds apply braking
resistors of higher capacity respectively pulse duty factor OD.
When calculating the braking resistor please take note that the installation efficiency is very important.
The above listed braking resistors are for standard installations. Further calculations for specific
installations on request.
The permissible duty cycle can be calculated approximately as follows:
Example: For an elevator with a rise of 12 m and a driving speed of 1 m / s, the permissible duty cycle
of the braking resistor is 10 %.
4.3 Ambient conditions
Ambient temperature 5 ... 50 °C
Maximum humidy 90% condensation not permissible
Maximum height 2000 m above 1000 m power-reduction 1% per 100 m
Degree of protection IP 20
4.4 Mains voltage cut-in frequency
A max. of 3 mains cut-in operations per minute is permissible.
Higher values may damage the converter!
