Converter AC Line Config Attributes
These are the regenerative converter AC Line configuration attributes associated with the AC Line input to a converter.
Converter AC Input Frequency
Usage | Access | T | Data Type | Default | Min | Max | Semantics of Values |
|---|---|---|---|---|---|---|---|
Optional - G | Set/SSV | USINT | 1 | - | - | Enumeration: 0 = 50 Hz 1 = 60 Hz 2-255 = Reserved |
The Converter AC Input Frequency attribute determines the nominal frequency of the AC Line connected to the converter.
Converter AC Input Phasing
Usage | Access | T | Data Type | Default | Min | Max | Semantics of Values |
|---|---|---|---|---|---|---|---|
Optional - G | Set/SSV | USINT | 0 | - | - | Enumeration: 0 = Three-Phase (R) 1 = Single-Phase (O) 2-255 = Reserved |
The Converter AC Input Phasing attribute determines whether the Converter input power to AC line is Single-Phase or Three-Phase.
Converter AC Input Voltage
Usage | Access | T | Data Type | Default | Min | Max | Semantics of Values |
|---|---|---|---|---|---|---|---|
Optional - G | Set/SSV | UINT | 480 | 0 | maxint | Volts (RMS) |
The Converter AC Input Voltage attribute configures the converter for the intended AC line voltage during normal operation.
AC Line Voltage Unbalance Limit
Usage | Access | T | Data Type | Default | Min | Max | Semantics of Values |
|---|---|---|---|---|---|---|---|
Optional - G | Set/SSV | REAL | 3 | 0 | 100 | % of Nominal |
The AC Line Voltage Unbalance Limit attribute sets the maximum allowed voltage unbalance between the AC line phases. Exceeding this limit results in a Converter AC Unbalance exception. Nominal voltage is defined by the AC Line Voltage Nominal attribute.
AC Line Current Unbalance Limit
Usage | Access | T | Data Type | Default | Min | Max | Semantics of Values |
|---|---|---|---|---|---|---|---|
Optional - G | Set/SSV | REAL | 3 | 0 | 100 | % of Rated |
The AC Line Current Unbalance Limit attribute sets the maximum allowed current unbalance between the AC line phases. Exceeding this limit results in a Converter AC Unbalance exception. Rated current is defined by the Converter Rated Input Current attribute.
AC Line Resonance Damping Gain
Usage | Access | T | Data Type | Default | Min | Max | Semantics of Values |
|---|---|---|---|---|---|---|---|
Optional - G | Set/SSV | REAL | 0 DB | 0 |  | Volts/Amp |
The AC Line Resonance Damping Gain sets the gain for active damping of resonant currents in the AC line filter.
AC Line Sync Kn
Usage | Access | T | Data Type | Default | Min | Max | Semantics of Values |
|---|---|---|---|---|---|---|---|
Optional - G | Set/SSV | REAL | 500 | 0 | | Radians/Volt/Sec |
The AC Line Sync Kn sets the proportional gain.
AC Line Sync Configuration
Usage | Access | T | Data Type | Default | Min | Max | Semantics of Values |
|---|---|---|---|---|---|---|---|
Optional - G | Set | BYTE | 0x04 0:0 1:0 2:1 | - | - | Bit Field: 0: Ig nore Voltage Unbalance 1: Ignore Voltage DC Offset 2: Use Internal Center Frequency 3-7: Reserved |
The AC Line Sync configuration controls the operation of the AC Line Synchronization function of regenerative converters.
Ignore Voltage Unbalance: When this bit is set the line synchronization ignores measured voltage unbalance.
Ignore Voltage DC Offset: When this bit is set the line synchronization ignores measured DC voltage offset.
Use Internal Center Frequency: When this bit is set the line synchronization uses an internal vendor specific value as the center frequency. When this bit is clear, the line synchronization uses the Converter AC Input Frequency as the center frequency.
AC Line Sync Error Tolerance
Usage | Access | T | Data Type | Default | Min | Max | Semantics of Values |
|---|---|---|---|---|---|---|---|
Optional - G | Set/SSV | REAL | 10 | 0 | 90 | Degrees |
The AC Line Sync Error Tolerance attribute sets the maximum allowed phase error associated with the AC line synchronization function of the regenerative converter. Exceeding this limit results in an AC Line Sync Loss exception.
AC Line Sync Kj
Usage | Access | T | Data Type | Default | Min | Max | Semantics of Values |
|---|---|---|---|---|---|---|---|
Optional - G | Set/SSV | REAL | 86666 | 0 | | Radians/Volt/Sec 2 |
The AC Line Sync Kj sets the integral gain of the AC Line Synchronization function in a regenerative converters.
AC Line Sync Kn
Usage | Access | T | Data Type | Default | Min | Max | Semantics of Values |
|---|---|---|---|---|---|---|---|
Optional - G | Set/SSV | REAL | 500 | 0 | | Radians/Volt/Sec |
The AC Line Sync Kn sets the proportional gain of the AC Line Synchronization function in a regenerative converters.
Demonstration Mode Select
Usage | Access | T | Data Type | Default | Min | Max | Semantics of Values |
|---|---|---|---|---|---|---|---|
Optional - BD | Set | USINT | 10 | 0 | 90 | Enumeration: 0 = Inactive 1 = Active 2-255 = (reserved) |
Activating Demonstration Mode, or ‘Demo Mode’, allows the associated converter and inverter power structures to operate using Single-Phase, 110/120 VAC, 50/60Hz, AC line input. Converter and inverter performance is significantly limited as compared to standard operation with Demo Mode inactive. All converter and inverter modules in a common DC bus configuration should have the same Demo Mode setting to avoid faulting.
The purpose of Demo Mode is to allow demonstration of products in non-industrial environments. It is not intended for use in real motion applications.
