Program explanations:
a) When X7 is triggered, M1144 will enable an acceleration. Set M1149 (counting temporarily stops) and 10
pulses will be sent out before the deceleration switch X0 is triggered and the program will enter the
deceleration section.
b) When X0 is disabled (i.e. zero return is completed), set M1148 to disable this function.
Note: The example offered here is one of the applications. Please adjust the settings of the parameters according to
the features of and restrictions on your machines.
