POINT
The following table summarizes the changes from MR-J3 series to MR-J4 series.
For details, refer to the reference document/items.
For large capacity models of 30 kW or more, Refer to "Part 5: Review on
Replacement of MR-J3-DU_ with MR-J4-DU_"
Connector shape, pin arrangement, signal abbreviation,
and location are different.
Terminal block shape, location, and method of drawing out
wires are different.
MR-J4 servo amplifier has P3 and P4 in the upstream of
the inrush current suppression circuit. Note that the
locations of the P1 and P terminals of MR-J3-11K_ to MR-
J3-22K_ are different.
There is no difference caused by the replacement from the
MR-J3 servo amplifier to the MR-J4 servo amplifier.
General-purpose interface is upward compatible, but the
parameter needs to be changed. The parameter converter
function of MR Configurator2 can transfer the parameter
setting for MR-J3 to the setting for MR-J4. For SSCNET III
interface, the MR-J3 compatibility mode is available with the
MR-J4 series and the parameter does not need to be
changed.
MR-J3 and MR-J4 have compatibility in mounting.
Note that the positions (clearances) of mounting screws for
the 5 kW (200 V), 3.5 kW (400 V), 11 kW, and 15 kW have
been changed to reduce the size of external dimensions.
The servo motor has a different dynamic brake coasting
distance.
For MR-J4, in the shipping status, the servo motor
decelerates to stop during a forced stop or when an alarm
has occurred. The stop method for MR-J4 is different from
the method of when an emergency stop or a forced stop of
MR-J3 is enabled.
The time it takes to reach servo-on from power-on is
different.
Those for MR-J3 may not be usable. Select those for MR-
J4.
Those for MR-J3 may not be usable. Select those for MR-
J4.
Those for MR-J3 may not be usable. FR-HAL is
recommended.
Those for MR-J3 may not be usable. FR-HEL is
recommended.
Some regenerative options cannot be used for MR-J4.
Setup software (SETUP221E) cannot be used for MR-J4.
Use MR Configurator2.
"MR Configurator2" can also be used for MR-J4 series and
MR-J3 series.
Use MR-BAT6V1SET for MR-J4.
When more than 15 kW of HG-JR 1000 r/min series or
more than 22 kW of HG-JR 1500 r/min series is used,
setting changes are required for the following encoder
cables.
