A dead circuit stops a wired awning halfway out. Somfy answers that with the Compact Manual Override on the LT50 530R2 CMO, a crank socket in the motor head that turns the tube by hand. The motor runs on standard 4-wire control and carries 30 Nm at 14 rpm. That torque sits between the 25 Nm and 50 Nm wired CMO motors in the same LT50 range, and it covers the bulk of residential awning and shutter work.
Awnings and rolling shutters that have to move without power
Somfy publishes two applications for this reference: awnings and rolling shutters. Both hang outside, and both face the same problem during an outage. A retracted awning survives weather better than an extended one, and a shutter that drops and stays down blocks an opening you may need. The CMO head answers both cases. A homeowner cranks the awning in or the shutter up with no power at the motor.
30 Nm at 14 rpm suits a mid-size lateral arm awning or a shutter curtain of moderate weight. Torque follows tube diameter and roll weight. Size the motor from the finished tube and the weight of the fabric or slats it carries. Opening width alone will mislead you. An installer who needs more muscle moves up to the 50 Nm 550R2 CMO in the same family. One who needs less drops to the 25 Nm 525A2 CMO.
The CMO head and the crank hardware it needs
The Compact Manual Override puts a drive socket in the motor head. A crank handle engages an override shaft, the shaft meets the eye at the motor, and the operator winds the tube in either direction. Somfy sells that shaft as a separate part, because the drop from the motor head down to a comfortable crank position changes with every opening. The Somfy CMO Awning Override Shaft, 100mm with Geiger eye covers a short drop and uses the Geiger eye most awning hoods are cut for.
A CMO motor head carries its own bracket profile. An LT50 star plate will not hold it. Order a bracket cut for a CMO head, and check the override thread against the shaft in your hand before the awning hood goes on. Head clearance matters here. The CMO head adds length at the motor end, and the 30.98 in overall figure in the table below already includes it.

Figures above come from Somfy's own published data for reference 1045017 and from the Somfy 500 Series databook.
Tube fit, crowns and drives
Minimum tube inner diameter is 1.85 in. A tube narrower than that will not clear the motor body, which measures 1.77 in across. Motor length runs 30.98 in, so measure from the bracket face to the idler end before you order a tube or cut one down. Leave room for the crown at the drive end and the idler at the far end.
Round and octagonal tube each take their own crown and drive. The Somfy LT50 2.5" Round Crown and Drive Set fits 2.5 in round tube, the profile most lateral arm awnings use. The Somfy Octagonal LT50 70mm Crown and Drive Set fits 70 mm octagonal tube, which dominates rolling shutter work. If the crown already sits in a good tube and the drive wore out, the Somfy LT50/60 Octagonal 70mm Drive replaces the drive on its own.
Match the crown to the inside shape of the tube. A 70 mm octagonal crown will not seat in round tube, and a round crown spins inside an octagonal one. Dry-fit the crown and drive on the bench, slide the motor in, and check that the drive pin seats before you lift the assembly into the brackets.
Wiring and limit setting on a 4-wire motor
Standard 4-wire control gives you up, down, common and ground. A wired wall switch, a relay or a dry contact output drives the motor. The 2464 cable leaves the head at 6.56 ft, so plan the junction box inside that reach or add an approved extension in conduit. The motor draws 1.5 A at 120V 60 Hz and pulls 170 W while it runs. Standby draw reads 0 W.
Limits are mechanical on this motor. Two adjustment screws in the head set the upper and lower stop, and the gearbox allows 34 turns of travel between them. Set the limits with the tube free to turn, then run the awning or shutter through both directions under load and trim the screws. A CMO limit setting tool makes the adjustment easier on a mounted motor.
Class I insulation puts a ground on this motor. Bond it. IP 44 covers splashing water from any direction, which suits an awning hood or a shutter box but not direct immersion. Thermal protection holds for 5 minutes of continuous running. That covers the duty cycle an awning sees, and it will trip on a long test loop, so give the motor a rest between runs.
Order the 530R2 CMO and the parts that finish the job
The Somfy 530R2 CMO 120V 4-Wire Motor (1045017) ships with a 5 year Somfy warranty and UR certification. Somfy has built the 500 Series around this platform for years, and the LT50 crown, drive and bracket catalog behind it reaches almost any tube you will meet on a retrofit.
Most jobs need the crown, the drive, a CMO bracket and an override shaft on top of the motor. Order them in one go and the install finishes in a single visit. A tube you measured twice saves the second trip.
Frequently asked questions
What torque does the Somfy 530R2 CMO deliver?
Somfy rates this motor at 30 Nm, near 265 in-lb, at 14 rpm. That places it in the middle of the LT50 wired CMO range, above the 25 Nm 525A2 CMO and below the 50 Nm 550R2 CMO. Size from the finished tube diameter and the weight of the awning fabric or shutter curtain the tube carries.
What tube does the 530R2 CMO fit?
Minimum tube inner diameter is 1.85 in, and the motor body measures 1.77 in across with an overall length of 30.98 in. Use an LT50 crown and drive matched to the tube shape, 2.5 in round or 70 mm octagonal. The crown locates the motor in the tube and the drive transfers the torque.
Does the CMO override need a separate shaft?
Yes. The motor carries the override socket in its head, and the crank shaft comes as its own part so you can match the length to the drop from the motor head to the crank position. A 100 mm shaft with a Geiger eye covers short drops on awning hoods. Measure the drop before ordering.
How are the limits set on this motor?
Two mechanical screws in the motor head set the upper and lower stop, with 34 turns of travel available between them. Turn the screws with the tube free to rotate, run the shade through both directions under load, then trim. A CMO limit setting tool reaches the screws on a mounted motor.
