Reverse Speed Limit Input
Program Torque Torque Control
This parameter Enables/Disables the Reverse Speed Limit Input control
function. When enabled and operating in the Torque Control mode, the reverse

This parameter provides a value to be used as the Reverse Speed Limit setting
if F428 is selected at F427.
Speed Limit (torque=0) Center Value Reference
Program Torque Torque Speed Limiting
The system has the ability to limit the amount that the speed may vary as a
function of a changing load while operating in the Torque Control mode. This
parameter sets the input signal source or value that will be used to control the
allowable speed variance.
Settings:
0 — Disabled
