No interference with other devices is to be expected with network impedance less than Z
max
[Ohm]. In general, the maximum permissible network impedance will not be exceeded if the ma‐
chine is supplied at the transfer point with a rated current of I

2.12 Machine duty cycle
Calculating the cycling period
Cycling time = time under load + time at standstill
Calculating the duty cycle:
Duty cycle [%] =
time under load
time under load + standstill time
x 100
Example:
12 minutes
20 minutes
x 100 % = 60 %
The following values are valid for:
■ 20 °C ambient temperature
■ 30 % relative humidity
■ 1013 mbar air pressure
