Listing of the supported attributes
3 Get AtReference BOOL 1: The inverter currently runs at reference
speed or reference torque (depending on
attribute 6, DriveMode).
4 Get / Set NetRef BOOL • 0: Reference via local setting on the device
or terminal
• 1: Reference via network (e.g. from the
scanner)
6 Get / Set DriveMode USINT Drive mode:
• 1: Idle speed (frequency)
• 3: Torque control
In order to be able to use the torque control
for the assembly object instances 22 (0x16),
23 (0x17), 72 (0x48), 73 (0x49), this attribute
has to be written.
