However:
The RPS-80 supplies 80 kW and can return up to 80 kW to mains for an S1
duty cycle. For an S6-40% duty cycle it supplies 104 kW and can return
104 kW to mains.
The RPS-75 supplies 75 kW and can return up to 75 kW to mains for an S1
duty cycle. For an S6-40% duty cycle it supplies 97 kW and can return 97
kW to mains.
The RPS-45 supplies 45 kW and can return up to 45 kW to mains for an S1
duty cycle. For an S6-40% duty cycle it supplies 59 kW and can return 59
kW to mains.
The RPS-20 supplies 20 kW and can return up to 20 kW to mains for an S1
duty cycle. For an S6-40% duty cycle it supplies 26 kW and can return 26
kW to mains.
NOTE PRIOR TO INSTALLATION
Before installing an RPS power supply when using non-FAGOR motors, re-
member that:
INFORMATION. They all integrate an auxiliary 24 V DC, 8 A power
supply to feed its own control circuits and those of the modular drives
connected to them. Consequently, they will not require the auxiliary power
supply APS-24 to perform this function unless more than 8 A are required.
i
MANDATORY.
Any element that will be part of the drive-motor system powered by an RPS
must meet the isolation requirements described in EN 61800-5-1.
• All the components connected to the intermediate circuit must run perma-
nently on a voltage higher than 625 V in the intermediate circuit.
• If the motor temperature sensor is a KTY type, it must also meet the re-
quirements described in EN 61800-5-1.
RECOMMENDATION.
Configure the RPS power supply with the minimum bus voltage to satisfac-
torily meet the features required by the system.
