Overview
The 9450F is the same 700 kg·cm drivetrain as the 9450D, built in the side-mounted configuration: the mounting flange moves to the sides of the case and the output carries a machined lever arm instead of a bare spline. Same 100 × 50 × 97 mm body, 895 g, 24–30 V.
The point of the F layout is the load path. A side-mounted flange takes the reaction torque across a longer bolted face, and the lever arm puts the push-pull rod in line with the load instead of hanging a linkage off a spline. On a 700 kg·cm actuator that difference is what keeps the bracket from flexing.
This page covers the RS-485 / Modbus build: the same mechanics on a differential serial bus, which is what survives long cable runs and electrically noisy cabinets. Modbus keeps it compatible with industrial PLCs and HMIs. This build is the side-mounted F configuration.

How to size it
The side flange bolts to a face, not to a tray, so the bracket has to be flat and stiff over the full 122.7 mm width. Shim it rather than preloading one corner — a twisted flange shows up as current ripple at the output, not as a servo fault.
Same current budget as the D: 22.5 A stall at 30 V, 450 mA idle. The lever arm also means the load is applied off-axis from the shaft centre, so check the side load against the bearing rating before extending the arm.
FAQ
How is the 9450F different from the 9450D?
Mounting and output: the F is side-mounted with a lever arm, the D has the standard ear-mount case with a bare 25T spline. Drivetrain, torque and current ratings are the same.
What connector does it use?
The PWM, TTL and CAN builds end in a J30J-15TJL connector, supplied separately. The Modbus build ends in a socket, also with the cable ordered separately.
Does it speak standard Modbus?
The sheet specifies RS-485 Modbus as the command signal. Ask for the register map and the supported function codes before you write the PLC program — they are not printed on the inspection sheet.
How long can the cable be?
RS-485 is differential, so tens of metres are routine at moderate bit rates. Terminate the pair at both ends and keep the power pair separate.
