Motor Control Performance

V/F Mode
Speed Regulation: + / - 20% of motor slip with slip compensation enabled

Vector Mode
Under / Over Voltage Trip Levels
The following levels are not user adjustable and define the operating voltage levels of
the drive and brake chopper circuit.
Automatic Switching Frequency Reduction
The switching frequency selected in 2606 will be automatically reduced based on the
heatsink temperature according to the data in section. In addition, switching
frequency is reduced under the following conditions:

Output Frequency based Effective Switching Frequency Reduction
At low output frequency, Effective Switching Frequency is automatically reduced.
Hysteresis is applied to prevent continuous switching. The operation is according to
the following table:
Command Source Response Time
Digital Input <8ms
Analog Input <16ms
Modbus RTU Interface <8ms from receipt of valid command
Power Stage <10ms to enable output
