When coast to stop is specified in stopping method selection (n004), DC Injection Braking at stop does not operate.
6.5 Building Interface Circuits with External Devices
6.5.1. Using Sequence Input Signals (n035 to n039)
Multi-function contact input Terminal S2 to S6 functions can be changed when necessary by setting constants n035 to
n039, respectively. Neither of these parameters can receive a setting common with the other.
• Terminal S2 function: Set to n035
• Terminal S3 function: Set to n036
• Terminal S4 function: Set to n037
• Terminal S5 function: Set to n038
• Terminal S6 function: Set to n039
