Defined switching conditions in the CMAX
Value Description Condition
13 Stroke after
force Switching is only permissible in a
force record.
The preselected value is interĆ
preted as the stroke
1 (position
difference, with sign).
After reaching the MC condition
for the force task
2, monitoring
of the actual position is started.
The switch
3 occurs as soon
as the stroke 1 set in the pre−
selected value has been passed.
The stroke specified in the pre−
selected value refers to the actual
position at the time the MC condiĆ
tion was reached for the force
task
2.

Notes:
Ĉ The position could be difficult to reproduce and the absolute position is
usually no known or evident because the position at the time the MC condiĆ
tion was met is not output.
Ĉ The direction of the stroke must agree with the specified direction in which
the force acts. Otherwise, a diagnostic message (W27/E27) is output.
Ĉ If the stroke or speed monitoring is violated, the current positioning record is
ended and record switching does not occur.
Ĉ The timeout time (force) begins to elapse when the MC condition is met for
the force task. If the stroke is not reached within the timeout time, the curĆ
rent positioning record is ended, no record switching occurs, SPOS.MC is set
to 1 and a diagnostic message (W28/E28) is output.
Ĉ If the timeout time for force control is deactivated (set to 0), the drive waits
indefinitely for the switching position to be reached.
