Torque Per Amp (E16) is used in the automatic calculation of the speed controller gains.
RFC-S
Torque Per Amp (E16) is used for automatic speed controller gain set up, and so the correct value for the motor should be entered if this feature is
required.
The Inertia Compensation Total Inertia (E15), Torque Per Amp (E16) and Inertia compensation acceleration (E18) are used to produce a torque feed-
forwards value that should accelerate and decelerate the load at the required rate. This value can be used as a feed-forwards term that is added to
the speed controller output. Inertia Compensation Torque (E17) gives the torque as a percentage of rated torque.
This is the profile generator output acceleration rate, and is set in 100mm/s
