* Rated data with reference Aluminum plate 457mm x 457mm x 12.7mm
** Derating:
Brake motor option reduces continuous torque ratings by 1Nm.
Non-resolver feedback options reduce continuous torque ratings by:
AKM72 = 2.0 Nm AKM73 = 2.7 Nm AKM74 = 3.4 Nm
Motors with non-resolver feedback and brake option, reduce continuous torque by:
AKM72 = 3.9 Nm AKM73 = 5.1 Nm AKM74 = 6.2 Nm
For motors with optional shaft seal, reduce torque shown by 0.25 Nm and increase M
R
by the same amount.
*** Technical data with connector option H. In case of using the connector option C the standstill current is limited
to 23,5A.
