Specifying attributes for an AXIS_SERVO_DRIVE tag
The axis tags differ from the basic tag. The AXIS_SERVO_DRIVE tag
has these attributes
TuningSpeed
Specify the tuning speed in revolutions per second (any positive number).
Specify:
TuningSpeed := value
TuningTorque
Specify the tuning torque % rated (any positive number).
Specify:
TuningSpeed := value
DampingFactor
Specify the damping factor (any positive number).
Specify:
DampingFactor := value
DriveModelTimeConstant
Specify the drive model time constant (any positive number).
Specify:
DriveModelTimeConstant := value
PositionServoBandwidth
Specify the maximum allowable value for position bandwidth (any positive number), given
the damping factor. This parameter is disabled if the loop configuration is set to velocity.
Specify:
PositionServoBandwidth := value
VelocityServoBandwidth
Specify the unity gain bandwidth that is to be used to calculate the subsequent gains for a
motion apply axis tuning (MAAT) instruction (any positive number).
Specify:
VelocityServoBandwidth := value
TuningConfigurationBits
Specify the tuning configuration bits. Enter a hexadecimal number.
Specify:
TuningConfigurationBits := 16# value
