196 Unidrive SP Regen Installation Guide
www.controltechniques.com Issue Number: 2
10.4 Component data
The following parts may be used:
• Motoring drive
• Regen drive
• Regen inductor
• Softstart resistor
• Switching frequency filter (optional)
• EMC filter (optional)
•Varistors
•Fusing
• Contactors
• Overloads
In addition to the above the additional items are also required to
assemble a Unidrive SP Regen Brake Resistor replacement system:
• Isolating transformer
• DC bus diode
10.4.1 Regen inductors
The regen inductor duty is very arduous, and therefore, correct
component selection is critical. The most sensitive aspect being the
inductor linearity. Only inductors specified in this installation guide
should be used.
The regen inductor supports the difference between the PWM voltage
from the Regen drive and the sinusoidal voltage from the supply. One
three-phase regen inductor is required per Regen drive.
Each regen inductor is fitted with a 170°C thermistor mounted in the
centre coil. The thermistor is set to 170°C at which point the resistance is
1000Ω, beyond 170°C a rapid rise in resistance will be seen.
If the permissible cable lengths are exceeded additional cooling may be
required for the regen inductors, refer to section 4.4.4 Cable length on
page 41.
Table 10-21 200V Regen inductor specifications
Table 10-22 400V Regen inductor specifications
The internal EMC filter must be removed from drive.
CAUTION
The regen inductors have a normal operating temperature of
approximately 170°C depending upon the ambient and the
motor cable lengths. Care must be taken so that this does not
create a fire risk.
