To avoid an actuation of the controller back-up fuse, it is
recommended to wait about 1 min. between a main power
OFF/ON cycle.
For single phase connection the voltage ripple on the DC-bus is
25Vpp for 5A (peak current SC-610-2), 50Vpp for 10A (peak
current SC-610-5) and for 15 (peak current SC-610-7). This
can limit the max. Speed of the motor.
When the controller will be supplied directly from the main or
via autotransformer, it is
NOT PERMITTED to connect the Vcc-
to PE. This connection will damage the controller!
4.1.2 Mains Filter (strongly required)
Following results are desired through the application of mains filters:
The electronic system should be protected from high frequency interferences which could enter via the
mains cable (noise immunity) and vice versa the mains cable may not transmit interferences from the
electronic systems to the adjoining components (elimination of interference).
To choose the fitting mains filter types following points have to be considered:
1. The need of power of the connected controller. Thereby the capacity and the ability of peak phase current
has to be considered. The listed filter can be overloaded by 1.5 of the nominal current during 1 min./h.
2. The required or present mains impedance.
The table below shows the corresponding mains filter types:
