value 1 and the actual position value 2, in cyclic operation (phase 4),
are monitored for a maximum allowed actual position value difference
indicated in parameter
S-0-0391, Monitoring window feedback 2
. If
the absolute value of the difference is greater than the value of the
monitoring window, the
F2036 Excessive position feedback
difference
error message is generated.

The output of the position loop (P-0-0048) is limited to a maximum
absolute velocity value. The output signal of the position loop is a
velocity command value that already contains the additive component
for velocity feedforward, plus a possibly preset additive velocity
command value (S-0-0037). The limitation therefore has an effect on
the sum of the different command values.
6.5 Limitations
Overview
Limitations in Open-Loop Operation (U/f Operation)
To protect the device or motor the following parameterizable limitations
have been implemented in open-loop operation:
•
current and torque limitation
•

limitation
•
torque/force
limitation
•
stall protection loop for current limitation
•
current limitation loop
•
position
limitation
•
travel range limit switch
•
software limit switch
Limitations in Closed-Loop Operation
To protect the device or motor the following parameterizable limitations
have been implemented in closed-loop operation:
•
current and torque limitation
•
current
limitation
•
torque/force
limitation
•
velocity
limitation
•
position
limitation
•
travel range limit switch
•
software limit switch
