Note 1: The motor with an oil seal must be derated by 20% during use.
Note 2: Parameters in () are for the motors with a brake.
The parameter values in the preceding table are applicable when the motor works together 
with the Inovance servo drive and the armature coil temperature is 20°C.
The preceding table shows the characteristic parameters of the motor after the heatsink below 
is installed for the motor.
