Module Configuration Attributes
478 Rockwell Automation Publication MOTION-RM003I-EN-P - February 2018
are only applicable to axis instances whose associated Inverter Support bit is set.
Array elements that are not applicable or not configured are set to 0.
Regenerative Power Limit
Usage Access T Data Type Default Min Max Semantics of Values
Optional - D Set REAL[8] []=100 []=0 []= % Motor Rated
This 8-element array limits the amount of power allowed to transfer between the
motor and the DC Bus during regenerative braking of the motor load for a given
axis instance. When using an external shunt resistor, set this value to its maximum
value. Since this is regenerative power, the value of the limit is negative.
Note that each drive instance in a multi-axis drive module can have an
independently configured Regenerative Power Limit. The indexed elements of this
array correspond to axis instances 1 thru 8. Individual elements of this attribute
are only applicable to axis instances whose associated Inverter Support bit is set.
Array elements that are not applicable or not configured are set to 0.
Converter Regenerative Power Limit
Usage Access T Data Type Default Min Max Semantics of Values
Optional - BD Set REAL 100 0
% Converter Rated
Limits the amount of regenerative power allowed to transfer from the DC Bus to
the converter. When using an external shunt resistor, set this value to its
maximum value. Since this is regenerative power, the value of the limit is negative.
Converter Type
Usage Access T Data Type Default Min Max Semantics of Values
Optional - BD Set USINT 0 - - Enumeration:
0 = AC/DC Non-Regenerative
1 = AC/DC Regenerative
2 = DC/DC Non-Regenerative
3 = DC/DC Regenerative
4-127 = (reserved)
128-255 = (vendor specific)
Enumerated list used to identify the type of Bus Converter. In the CIP Motion
specification the term 'Converter' applies to any device function that converts AC
or DC input power to DC Bus output power that may be used by Inverter power
structures to drive motors.
