Subfunctions
The APC function module is subdivided into the following subfunctions:
● Active Vibration Suppression (APC without sensor on the load side) (Page 556):
– Is a rugged function to dampen oscillation.
– Does not require a direct measuring system
– Can be individually activated as function module "Active Vibration Suppression (AVS/
● APC to reduce machining-related oscillation (Page 562):
– Is a rugged function to dampen machining-related oscillation.
– Can be used in addition to other functions.
– Does not require a direct measuring system
● APC with encoder combination and differential position feedback (Page 565):
– The function is used to influence the speed control loop. The speed control response can
– Requires a direct measuring system.
– Encoder combination and differential position feedback are functions that are
● APC with acceleration feedback (Page 570):
– The function uses the acceleration measured using the direct measuring system to
– Requires a direct measuring system.
– An external acceleration sensor can be used instead of measuring the acceleration
● APC with load velocity control (Page 576):
– Requires a direct measuring system.
– The function controls the velocity at the direct measuring system. Oscillation is
