Max. torque (N⋅m)		25.2
Acceleration/Deceleration (Note 6)	Maximum speed (degree/s)	450
	Min. Speed (degree/s)	20
	Rated acceleration/deceleration (G)	0.3
	Max. Acceleration/Deceleration (G) (Note 7)	0.7
Brake	Brake specification	Non-excitation electromagnetic brake
Brake	Brake retention torque (N・m) (Note 8)	16

(Note 8) Allowable moment of inertia and brake retention torque are not necessarily compatible.

　Please confirm that the load torque is lower than the retention torque.

Important notes on selection

(1) The output torque decreases as the rotation speed increases. For details, please check the "Correlation diagram of rotational speed and output torque".
(2) The allowable moment of inertia of the rotating workpiece varies depending on the rotation speed. For details, please check the "Correlation diagram of rotational speed and allowable moment of inertia".
(3) The brake is for holding. Do not use for braking/emergency stop purposes.
(4) When making a selection, please calculate according to the "Selection method (page 2-95 onwards)" and check the usage conditions before making your selection.
(5) If push operation is required, please check the "Correlation diagram of pressing force and current limit value" first. Pressing force shown are their standard value.
(6) The maximum acceleration/deceleration is 0.7G in horizontal/ceiling position and 0.5G in sideways/vertical position.
(7) When connecting the RCON-EC connection specification (ACR) to the EC connection unit (RCON-EC-4), the number of connections that can be made is limited. Refer to page 2-798 for further details.
