11.2 Connected Unit Count Determination Method
Refer to the power capacity calculation method below in [Method of Calculating Rated Current and
Peak Current] and [Required Number of Power Supply Units], and determine the number so that the
load rated current and the peak current fall within the allowable range of the power supply.
· To calculate the MCON power supply current, refer to "1.3 Power Supply Capacity Calculation" in
the MCON instruction manual.
· To calculate the MSEP power supply current, refer to "1.3 Power Supply Capacity Calculation" in the
MSEP instruction manual.
·To calculate the RCP6S gateway system power capacity, refer to "1.3 Calculation of Number of
Connectable Axes and Power Capacity" in the RCP6S fieldbus communication instruction manual.
· For RCON, "calculator software", which automatically calculates the required power capacity, is
available by setting the operating conditions and operating pattern of the actuator, in order to
determine the number of connected PSA-24 power supply units.
Refer to the "Calculation Software Instruction Manual (ME0381)" for the operation method, etc.
If the following phenomenon occurs after actual operation, operation can be performed by connecting
the power supplies in parallel and increasing the number of units.
· Overcurrent protection circuit engages [Refer to "Protective Function Specifications" on page 1-5]
Power capacity calculation method
[Method of Calculating Rated Current and Peak Current]
Refer to Appendix Tables 1-1 to 1-8 for the rated current and maximum current for each actuator.
1. Models without rated current notation
Total rated current (A)= Maximum current per actuator (A) x Number of actuators
+ Control power supply current of each controller (A) x Number of controllers
2. Models with rated current notation
Total rated current (A) = Rated current per actuator (A) x Number of actuators
+ Control power supply current of each controller (A) x Number of controllers
Total peak current (A) = Maximum current per actuator (A) x Number of actuators simultaneously activated
+ Control power supply current of each controller (A) x Number of controllers
(Note) The controllers that include control power supply current in "Power Supply Current" of Tables
1-1 to 1-8 do not require separately adding the control power supply current of the controller.
(Note) If the controller is fieldbus specification, add 0.3A multiplied by the number of controllers.
