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

• current 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
