The FEEDBACKS block allows you to view speed feedback and motor current related diagnostics.
Parameter Descriptions
QUADRATIC TORQUE
Designed for all Motor Control Modes.
When TRUE, selects QUADRATIC allowing higher continuous ratings with less overload capability. Quadratic Torque
operation is especially suited to fan or pump applications. When FALSE, selects CONSTANT duty.
OVERLOAD LEVEL
Designed for all Motor Control Modes, except PMAC control mode.
This reduces I*t limit for shaftless printing applications. However, with OVERLOAD LEVEL set to LOW, no pwm
frequency reduction occurs during overload conditions.
Enumerated Value : Level
DC LINK VOLTS
This shows the voltage across the dc link capacitors.
TERMINAL VOLTS
This shows the rms voltage, between phases, applied by the Drive to the motor terminals.
