MR-CM simple converter

Combination of simple converter and servo amplifier

Selection method
Select a servo amplifier for connection that meets the following conditions.
• Connectable servo amplifier models
MR-J5-10_ to MR-J5-200_, MR-J5W2-22G_ to MR-J5W2-1010G_, MR-J5W3-222G_/MR-J5W3-444G_
• The sum of rated capacities of connected servo amplifiers [kW] ≤ 3 kW (MR-CM3K rated output)
For multi-axis servo amplifiers, the calculation uses the sum of the rated capacities of all axes as the rated capacity of one
servo amplifier.
• Number of connectable servo amplifiers to one MR-CM3K ≤ 6
A multi-axis servo amplifier is counted as one servo amplifier unit, rather than the number of axes.

Servo amplifier setting when using a simple converter

When using a simple converter, set [Pr. PA02.4] of the servo amplifier connected in the latter stage to "1" (simple converter is
used). If the simple converter is used without setting [Pr. PA02.4], unexpected alarms may occur.
The simple converter and the external regenerative option connected to the servo amplifier can be used together. To use an
external regenerative option, set [Pr. PA02.0-1]. Note that the simple converter does not have a regenerative function. Also,
an external regenerative option cannot be connected to the simple converter.
