5.9.2 Speed comparators
The message “Speed comparator active” is set when the following two conditions are fulfilled:
– The actual speed is within the parameterisable limits
( › minimum and š maximum).
– The first condition has at least been fulfilled over the specified time period (damping time).
In all other cases the message is inactive.
When the drive leaves the speed zone again, the message is reset immediately.
The speed comparators can be used in all operating modes (positioning mode, speed mode, force
mode).

You can allocate this signal to digital output 6 or 7 in FCT on the “Digital I/O” panel.
1) The limit values can be both positive and negative. If the minimum value is greater than the maximum value, the condition for the
speed comparator is never fulfilled.

5.9.3 Force comparators
The message “Force comparator active” is set when the following two conditions are fulfilled:
– The actual force calculated with the help of the measured current is within the parameterisable
limits ( › minimum and š maximum).
– The first condition has at least been fulfilled over the specified time period (damping time).
In all other cases the message is inactive.
When the drive leaves the force zone again, the message is reset immediately.
The force comparators can be used in all operating modes (positioning mode, speed mode, force
mode).

You can allocate this signal to digital output 6 or 7 in FCT on the “Digital I/O” panel.
1) The limit values can be both positive and negative. The prefix here indicates the direction of the force. If the minimum value is
greater than the maximum value, the condition for the force comparator is never fulfilled.
