Servo motor
Mounting compatibility
Some models have no mounting compatibility.
Part 7, Section 1.1
Dimensions
The total length may differ depending on models.
Part 7, Section 2.1
Part 7, Section 2.2
Part 7, Section 2.3
Reducer
The actual reduction ratio of HF-KP and HF-MP series G1
types may differ from that of HG-KR series G1 types
depending on models.
Part 7, Section 2.3
Part 7, Section 2.4
Moment of inertia
The moment of inertia of the HF-_P/HC-_P/HA-_P motor
may differ from that of the HG motor depending on
models. (Note)
Part 7, Section 2.5
Load to motor inertia ratio
The range of the load to motor inertia ratio for the servo
motor may differ between the HF-_P/HC-_P motor and the
HG motor depending on models.
Part 7, Section 2.5
Connector
The power connector, encoder connector, and
electromagnetic brake connector may differ from one
another in shape.
Part 7, Section 2.6
Torque characteristics
The torque characteristics of the HF-_P/HC-_P motor may
differ from those of the HG motor.
Part 7, Section 2.7
Rated speed/maximum speed
The Rated speed/maximum speed of the HF-_P/HC-_P
motor may differ from those of the HG motor.

Instruction Manual
(Vol. 3)
Encoder resolution
The encoder resolution differs as follows.
HF-_P/HC-_P motor: 18bit ABS
HG motor: 22 bit ABS

Controller
(SSCNET
interface only)
MR-J4W2-_B servo amplifiers have two operation modes.
"J4 mode" is for using all functions with full performance and
"J3 compatibility mode" is compatible with MR-J3W-_B
series for using the amplifiers as the conventional series.
When you connect an amplifier with SSCNET III/H
communication for the first controller communication with
the factory setting, the operation mode will be fixed to "J4
mode". For SSCNET III communication, the operation mode
will be fixed to "J3 compatibility mode".
Note. This may change the motor inertia, making it necessary to adjust the servo gain.
