Function:
Select the interface at which to receive feedback from the motor.
A and B channel encoder, which can be connected to the digital input terminals 32/33 only. Termi-
nals 32/33 must be programmed to
Encoder module option which can be configured in par. group 17-1*
This parameter appears in FC 302 only.
Optional resolver interface module which can be configured in par. group 17-5**
encoder interface 2 of the optional programmable motion controller MCO 305.
Function:
Select the torque characteristic required.
VT and AEO are both energy saving operations.
Motor shaft output provides constant torque under variable speed control.
Motor shaft output provides variable torque under variable speed control. Set the variable torque
level in par. 14-40
Automatically optimises energy consumption by minimising magnetisation and frequency via
AEO Minimum Magnetisation

This selection maybe unavailable depending on drive configuration.
Function:
Allows up to 160% over torque.
For oversized motor - allows up to 110% over torque.
