 Setting Operation Conditions
 Reverse Run Prohibit (n05)
The Reverse Run Prohibit setting disables accepting a reverse RUN
command from the control circuit terminal or Digital Operator. This set-
ting is used for applications where a reverse RUN command can cause
problems.
 Multi-step Speed Selection
Up to 16 speed steps (including Jog frequency reference) can be set
using the following combinations of frequency reference and input ter-
minal selections.
Setting Description
0 Reverse run enabled.
1 Reverse run disabled.
