Reset
Within a part program, a modified control range limit can be reset by explicitly programming
CLC_LIM without a "CLC_LIM( )" argument. This reapplies the limits from the following
machine data:
• MD62505 $MC_CLC_SENSOR_LOWER_LIMIT[0] (lower clearance control motion limit)
• MD62506 $MC_CLC_SENSOR_UPPER_LIMIT[0] (upper clearance control motion limit)
RESET response
The default setting from the above-mentioned machine data becomes effective after power
on reset, NC RESET and end of program.
Error messages
The following programming errors are displayed with an alarm:
• Programming more than 2 arguments
• Programming arguments outside the permissible limits
2.6.4 Direction-dependent traversing motion disable
Syntax
$A_OUT[
Number
Number of the parameterized digital output (see below: Parameterization)
• Format: Integer
• Range of values: 1, 2, . . . max. number of digital outputs
Enabling signal
Enabling signal, can be inverted (see below: Parameterization)
• Format: Integer
• Range of values: 0, 1
System variable $A_OUT[n] can be set block-synchronously in the part program or
asynchronously via synchronized actions.
