Parameterization
The following machine data is used to parameterize the digital outputs:
● MD62523 $MC_CLC_LOCK_DIR_ASSIGN_DIGOUT[n] (assignment of the digital outputs
for disabling the CLC movement)
n = 0 → Digital output for disabling the negative traversing direction
n = 1 → Digital output for disabling the positive traversing direction
Example
The following digital outputs are to be used:
● $A_OUT[3] to disable the negative traversing direction
● $A_OUT[4] to disable the positive traversing direction
Parameter settings in the machine data:
● MD62523 $MC_CLC_LOCK_DIR_ASSIGN_DIGOUT[0] = 3 (assignment of the digital
outputs for disabling the CLC movement)
● MD62523 $MC_CLC_LOCK_DIR_ASSIGN_DIGOUT[1] = 4
Effect:
● $A_OUT[3] = 0 → Negative traversing direction enabled
● $A_OUT[3] = 1 → Negative traversing direction disabled
● $A_OUT[4] = 0 → Positive traversing direction enabled
● $A_OUT[4] = 1 → Positive traversing direction disabled
Inversion of the evaluation
Enter the negative number of the digital output to evaluate the digital output signal with
inversion:
Parameter settings in the machine data:
● MD62523 $MC_CLC_LOCK_DIR_ASSIGN_DIGOUT[0] = -3 (assignment of the digital
outputs for disabling the CLC movement)
● MD62523 $MC_CLC_LOCK_DIR_ASSIGN_DIGOUT[1] = -4
Effect:
● $A_OUT[3] = 0 → Negative traversing direction disabled
● $A_OUT[3] = 1 → Negative traversing direction enabled
● $A_OUT[4] = 0 → Positive traversing direction disabled
● $A_OUT[4] = 1 → Positive traversing direction enabled
