Note 1. Use the renewal tool if using an existing encoder cable (including options).
(Refer to "[Appendix 2] Introduction to Renewal Tool".)
For HA-LFS 1000 r/min series of 15 kW or more, HA-LFS 1500 r/min series of 22 kW or more, and HA-LFS 2000 r/min series
of 30 kW or more, their substitute models have different thermal wiring from them. A new encoder cable is required when
using the substitutes.
2. This may change the motor inertia, making it necessary to adjust the servo gain.
Impact
Some regenerative options cannot be used for MR-J4.
Setup software (SETUP161E) cannot be used for MR-J4.
Use MR Configurator2.
Use MR-BAT6V1SET for MR-J4.
Replace the encoder cable because the shape of the CN2
connector is different. (Note 1)
An HIV wire is recommended for MR-J4. Therefore, when HIV
wires are not used for those already laid, use the renewal tool.
Some dynamic brakes cannot be used for MR-J4.
The recommended EMC filter is different.
The panel through attachment cannot be used for MR-J4.
Some models have no mounting compatibility.
Although HC-SFS, HC-UFS and HA-LFS series have an oil
seal, substitute models do not come with an oil seal. Use
models having an oil seal when necessary.
The total length may differ depending on models.
The HG motor has no G2-type reducer for high precision
applications.
The reducer efficiency differs between G2-type and G7-type.
In addition, the actual reduction ratio of HC-KFS and HC-MFS
series G1 types may differ from that of HG-KR series G1
types depending on models.
The moment of inertia of the HC-_FS/HA-_FS motor may
differ from that of the HG motor depending on models. (Note
2)
The range of the load to motor inertia ratio for the servo motor
may differ between the HC-_FS/HA-_FS motor and the HG
motor depending on models.
The power connector, encoder connector, and
electromagnetic brake connector may differ from one another
in shape.
The torque characteristics of the HC-_FS/HA-_FS motor may
differ from those of the HG motor.
The Rated speed/maximum speed of the HC-_FS/HA-_FS
motor may differ from those of the HG motor.
For HG-JR 1000 r/min series of 15 kW or more and HG-JR
1500 r/min series of 22 kW or more, the thermal sensor is
replaced with a thermistor. For HG-JR 1000 r/min series of 12
kW or less and HG-JR 1500 r/min series of 15 kW or less, the
thermal sensor is removed.
The encoder resolution differs as follows.
HC-_FS/HA-_FS motor: 131,072 pulses/rev
HG motor: 4,194,304 pulses/rev
The SSCNET positioning module and motion controller need
to be replaced with the SSCNET III/H positioning module and
motion controller. When using an existing controller, refer to
"[Appendix 1] MR-J4-_B_-RJ020+MR-J4-T20".
