Instance Attribute "SpeedRef"
This attribute allows reading and writing of the speed reference set point. The unit of the attribute
must be (RPM / 2
If the SpeedScale attribute is not used by the master, the default unit [1 RPM] is assumed. This is
equivalent to the value 0 being used for SpeedScale.
Instance Attribute "TorqueActual"
This attribute allows reading of the torque actual value. The unit of the attribute must be (Nm /
TorqueScale
2 ), where the TorqueScale is attribute 24
If the TorqueScale attribute is not used by the master, the default unit [1 Nm] is assumed. This is
equivalent to the value 0 being used for the TorqueScale.
Instance Attribute "TorqueRef"
This attribute allows reading and writing of the torque reference set point. The unit of the attribute
TorqueScale
must be (Nm / 2
If the TorqueScale attribute is not used by the master, the default unit [1 Nm] must be assumed. This
is equivalent to the value 0 being used for TorqueScale. To set the drive to the torque control, see
Chapter 14 "APPENDIX 4 - FIELDBUS PARAMETRISATION".
Instance Attribute "ProcessActual"
This attribute allows reading of the process actual value. The unit of the attribute must be (% /
ProcessScale
2 ), where the ProcessScale is attribute 25
supported. See Chapter "9.3.1.1.4. Assembly Instance 25 – Extended Process Control Output" for
details.
Instance Attribute "ProcessRef"
This attribute allows reading and writing of the process reference set point. The unit of the attribute
ProcessScale
must be (% / 2
not supported. See Chapter "9.3.1.1.4. Assembly Instance 25 – Extended Process Control Output"
for details.
Instance Attribute "SpeedScale"
The SpeedActual and SpeedRef values are scaled according to the value of this attribute. The default
value is 0 .
d
The largest allowed value for this attribute is 7 (allowing resolution of 0.0078 RPM) and the
minimum allowed value is -4 (allowing resolution of 16 RPM). The maximum speed value for input/
output is thus ca 524000 RPM.
Instance Attribute "TorqueScale"
The TorqueActual and TorqueRef values are scaled according to the value of this attribute. The
default value is 0
The largest allowed value for this attribute is 7 (allowing resolution of 0.0078 Nm) and the minimum
allowed value is -8 (allowing resolution of 256 Nm). The maximum torque value for input/output is
thus ca 8.4 MNm.
Instance Attribute "RefFromNet"
This attribute reveals whether the torque or speed reference is local or from the network. If the
reference is local, the value of the attribute is 0. If the reference is from the network, then the value
of the attribute is 1.
