Break-away and acceleration torques dependent on motor con-
trol method
The table above indicates what typical torque is available on the motor
shaft of an asynchronous machine when the machine is driven by a
CDA3000 inverter module. The maximum motor rated current is limited by
the inverter module to 2 x I
N-Motor
.
For data relating to the servomotors refer to section 2.5.2.
