10.4.2 Softstart resistor - type TG series
The start-up circuit limits the amount of current flowing into the DC bus of
the Regen drive and motoring drive(s) when the supply is first switched
on.
The softstart resistors required for single regen multiple motoring
applications are as specified in the following table. Resistor energy pulse
rating and overload are non-standard and therefore important.
The following resistors can be configured to meet the required
resistance (series parallel arrangements).
Table 10-24 Softstart resistor
Softstart resistor MCB
Protection for the softstart circuit is provided using a thermal overload to
protect against a high impedance short circuit, and a separate magnetic
overload to protect against a direct short circuit.
Table 10-25 Softstart resistor MCB
10.4.3 Switching frequency filter
The AC input terminals of a Regen drive produce a PWM output voltage,
which has a sinusoidal component at line frequency, plus significant
harmonics at the switching frequency and its multiples.
Switching frequency filter inductors
The following inductors are standard 3-phase inductors, rated at drive
rated current for a single regen system. They carry only 50/60Hz current
with a negligible amount of high frequency current.
The switching frequency filter inductors need to be rated to the total
current requirement of the system.
