Rockwell Automation 8720MC 8720MC Regenerative Power Supply User Manual - Manual (Page 99)

This parameter sets the rated input current in units of amperes. The set value affects the FWD and REV
Current Limits (U.001 and U.002), overload detection, etc.
In case of paralleled units, the total current value of the connected units must be set to this parameter.
When pressing the
key or the key, the displayed value changes 1 Amp per stroke in case of single
unit, 2 Amps per stroke in case of two paralleled units, and 3 Amps per stroke in case of three paralleled
units.
The Rated Current cannot been changed, when the password has not been set, while operating even if the
password has already been set, or when an error occurred.
ATTENTION: Only qualified electrical personnel familiar with the construction and
operation of this equipment and the hazards involved should change this parameter.
Read and understand this instruction manual in its entirety before proceeding. Failure
to change parameter values could result in destruction of the equipment, severe bodily
injury or loss of life.
Parameter Range: 10 to 35 Amps 15 kW unit (single 15 kW unit)
20 to 70 Amps 30 kW unit (2 paralleled 15 kW units)
30 to 105 Amps 45 kW unit (3 paralleled 15 kW units)
10 to 70 Amps 37 kW unit (single 37 kW unit)
20 to 140 Amps 75 kW unit (2 paralleled 37 kW units)
30 to 210 Amps 110 kW unit (3 paralleled 37 kW units)
30 to 215 Amps 125 kW unit (single 125 kW unit)
60 to 430 Amps 250 kW unit (2 paralleled 125 kW units)
90 to 645 Amps 375 kW unit (3 paralleled 125 kW units)
Default Setting: 28 Amps 15 kW unit (single 15 kW unit)
56 Amps 30 kW unit (2 paralleled 15 kW units)
84 Amps 45 kW unit (3 paralleled 15 kW units)
65 Amps 37 kW unit (single 37 kW unit)
130 Amps 75 kW unit (2 paralleled 37 kW units)
195 Amps 110 kW unit (3 paralleled 37 kW units)
190 Amps 125 kW unit (single 125 kW unit)
380 Amps 250 kW unit (2 paralleled 125 kW units)
570 Amps 375 kW unit (3 paralleled 125 kW units)
Parameter Type: Requiring the password, configurable only while the unit stops

U.002 REV Current Limit
F.001 Unit Selection
F.002 Rated Current (Note 1)
This parameter sets the
rated input current of the
8720MC-RPS
Regenerative Power
Supply. In case of multiple
units connected in parallel,
the total current of the
connected units must be
set.
For most applications, it is
recommended that this
parameter not be adjusted.
Note 1: This parameter is
available from software
version No. 3.00 (to be
shown on the parameter
F.018) or later only.
Parameters 7-7
Larger values of the Current Control Proportional Gain set in this parameter result in faster response of the
current control loop. But if the gain is set to a too large value, the unit becomes more susceptible to
overcurrent detection and unstable by starting vibration of input current. Decreasing the gain value will help
increase stability, but result in less respondence.
F.003 Current Control Proportional Gain
This parameter determines
the response of the current
control.
For most applications, it is
recommended that this
parameter not be adjusted.
Parameter Range: 0.01 to 10.00 times
Default Setting: 1.00 times
Parameter Type: Requiring the password, configurable only when the unit is normal
