Defined switching conditions in the CMAX

Value

Description

Condition

14

Position at
force

Switching is only permissible in a
force record.
The preselected value is interĆ
preted as the position value

1.

Switching occurs as soon as the
current actual position reaches
the preselected value, indepenĆ
dently of whether the MC condiĆ
tion for the force task has already
been met (case

3, signals with

solid lines) or not (case

2, sigĆ

nals with dashed lines).
Attention: SPOS.MC (Motion ComĆ
plete) is not set to 1 during record
processing, but only when the
CMAX has carried out the last
chained record.

Notes:
Ĉ The direction of the switching position with respect to the starting position

must agree with the specified direction of the acting force. 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 again when the MC condition is

met for the force task. If the switching position is not reached within the
timeout time, the current 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.
