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.
