Drive Output Attributes
These are the inverter output related attributes associated with a Motion Control Axis.
Output Frequency
Usage | Access | T | Data Type | Default | Min | Max | Semantics of Values |
|---|---|---|---|---|---|---|---|
Required - F Optional - C | Get | T | REAL | - | - | - | Hertz |
The Output Frequency attribute is the time averaged output frequency applied to motor. Frequency value is in terms of electrical cycles.
Output Current
Usage | Access | T | Data Type | Default | Min | Max | Semantics of Values |
|---|---|---|---|---|---|---|---|
Required - D !LTM | Get | T | REAL | - | - | - | Amps (RMS) |
The Output Current attribute is the output current applied to motor.
Output Voltage
Usage | Access | T | Data Type | Default | Min | Max | Semantics of Values |
|---|---|---|---|---|---|---|---|
Required - D !LTM | Get | T | REAL | - | - | - | Volts (RMS) |
The Output Voltage attribute is the phase-to-phase output voltage applied to motor.
Output Power
Usage | Access | T | Data Type | Default | Min | Max | Semantics of Values |
|---|---|---|---|---|---|---|---|
Required - D | Get | T | REAL | - | - | - | Kilowatts |
The Output Power attribute is the mechanical output power of the motor. This value represents the product of applied motor torque/force and motor speed. If the axis is configured for Frequency Control, the Velocity Feedback signal is derived from the Velocity Reference signal.
PWM Frequency
Usage | Access | T | Data Type | Default | Min | Max | Semantics of Values |
|---|---|---|---|---|---|---|---|
Optional - D | Set | T | UINT | - | - | - | Hertz |
The PWM Frequency attribute sets the carrier frequency for the Pulse Width Modulation output to the motor. Drive derating is required at higher PWM frequencies due to switching losses. Current loop update time is tied directly to the PWM frequency so loop performance generally increases with increasing PWM rate.
