1.2 General Description
u Z1000 Model Selection
Refer to Table 1.1 for drive selection depending on the motor power and Normal Duty (ND) or Heavy Duty (HD) rating.
Note: The models and capacities in shown here are based on standard settings and operation conditions. Higher carrier frequencies and higher
ambient temperatures require derating.
