6.2.2 Input
Control commands
Start and stop the connected motor with the LCP and digital inputs.
Functions are divided into 2 groups. Functions in group 1 have higher priority than functions in group 2.
Table 31: Function Groups
Group 1 Coast stop, reset and coast stop, quick stop, DC braking, stop, and [OFF].
Group 2 Start, latched start, start reversing, jog, freeze output, and [Hand On].
6.2.3 Motor
Motor running
