HARDWARE
The user must configure the QC-RPS-160-SN0 power supply with:
1. The minimum DC BUS voltage required to properly meet the features
required by the system (especially with the needs of the motors installed
and
2. A voltage setpoint no lower than 1.48 x Vline, approximately.
The possible configuration it offers are:
QC-RPS-160-SN0 power supplies will always work in the mode
configured by the switches: either RPS mode or RB6 mode.
·1· RPS operating mode. Increase to the VP5 voltage value. The value of
the DC BUS voltage must be approximately that set by the user in
parameter VP5 of the QC-RPS power supply. By default, this value is
650 V DC. MAX. 725 V DC.
Select this configuration if 440 V AC
 Vline  420 V AC.
If it cannot properly meet the features required by the system, change the
value of VP5.
·2· RPS operating mode. Boost to 625 V DC. The DC BUS voltage is
lower than 625V DC, approx.
Select this configuration if 420 V AC  Vline  400 V AC. If the features
required by the system are not met, choose another switch configuration
to obtain a higher DC BUS voltage.
·3· RPS operating mode. Boost to 600 V DC. The DC BUS voltage is lower
than 600 V DC, approx.
Select this configuration if V
line  400 V AC.
If the features required by the system are not met, choose another switch
configuration to obtain a higher DC BUS voltage.
·4· RB6 operating mode. Maintain 1.41xV line. The voltage value of the
DC BUS will be the rectified value of the mains peak voltage.
Select this configuration if Vline  440 V AC. Note, however, that the RB6
operating mode can be configured for any line voltage. If it cannot
satisfactorily meet the features required by the system with this switch
configuration, choose another one.

INFORMATION. The QC-RPS-160-SN0 regenerative power supplies leave
the factory with the switches configured to option 2 (625 V DC). IMPORTANT.
Make sure software version 01.01 or higher is installed on the power
supply.
