SPEED ERROR
(26)
This block
• selects the source for speed error
calculation (speed reference -
actual speed) in different control
modes
• selects the sources for speed
reference and speed reference
feedforward
• defines the speed error filtering
time
• defines an additional speed step to
the speed error
• defines the supervision of speed
error with the speed error window
function
• defines inertia compensation during
acceleration
• shows the used speed reference,
filtered speed error and the output
of the acceleration compensation.
