FIG 7-50 Signal-flow chart (section) for additional torque set-values
Purpose
The additional torque set-values can be used for friction compensation or
acceleration (dv/dt)
Parameter setting
1. Input
With the function ”freely assignable analog inputs” eachinputcanbeassignedto
a ”terminal signal” from the table in C145.
If signals are assigned to the inputs, the inputs codes are for display only. If the
terminal control is deactivated, the actual terminal value will be accepted for
operation.
