7 PROTECTION COORDINATION MODE
DISABLED (STANDALONE DRIVE)
• Do not apply power to the main circuit power supply terminals (L1/L2/L3) of the servo amplifier. Doing so will cause the
servo amplifier and converter unit to malfunction.
• Connect the polarities of the DC power supply between the converter unit and the servo amplifier correctly. Connecting
them incorrectly will cause the converter unit and servo amplifier to malfunction.
• Only the MR-J4 series can be used with the protection coordination mode disabled (standalone drive).
• When using a servo amplifier other than a drive unit in combination with the converter unit, set the rotary
switch for converter setting (SW1) of the converter unit to "8" to disable protection coordination mode.
• The regenerative capacity cannot be improved by connecting two or more converter units in a row. Two or
more converter units cannot be connected to the same DC power supply line.
• When using a servo amplifier and converter unit in combination, set the parameters of the servo amplifier to
enable EM1 (Forced stop 1).
• In this configuration, only the STO function is supported. The forced stop deceleration function cannot be
used.
• When using the converter unit, set the parameters of the servo amplifier.
In this chapter, the connection between the MR-CV_ power regeneration converter unit and the servo amplifier is explained
using the MR-J4-_B_ servo amplifier as an example.
