HARDWARE
It is also highly recommended to use auto-transformers instead of isolating
transformers when only an adaptation of the working voltages is required.
Remember that if the isolating transformer is installed, depending on its
power and impedance, it may be required to install a second choke in series
with the one that musts be installed with XPS power supplies.
MANDATORY. For systems with XPS power supplies, install isolating
transformers ONLY when the type of mains so requires.
WARNING. Not complying with the previous indications could cause the DDS
system to perform poorly.
INFORMATION. When using a transformer, it is preferable to install an RPS
power supply in RB6 mode (rectifier) rather than an XPS power supply. The
operation will be similar to that of the XPS with less disturbances in mains,
smaller voltage variations at the motor, less noise, etc.
INFORMATION. When in a system with XPS power supply, the pulses of the
drives are activated, a very low frequency blinking (flashing) may be observed
on the amber LED of energy regeneration to mains. THIS BEHAVIOR IS
NORMAL and does NOT indicate that the system is not working properly.
Deactivating the pulses, the LED will stop blinking.
