(Index 4000h) Control input command (w) / Inverter status (r)
Sub Index
Data type
Default value
00h
Access attribute
Availability of mapping to PDO Enable
<Detail>
Perform control command to the inverter. And read the inverter status.
When written at the same time as Index 4010h control input command (w) (written at the same time with
SDO and PDO), the latter writing has priority.
(1) Control input command (Writing)
The following items can be sent to the inverter as control input command.

JOG (jog operation selection)
*1 Signal names are initial values. Definitions change according to the Pr. 180 to Pr. 189 (input terminal function selection).
*2 The signal within parentheses is the default setting. Since jog operation/automatic restart after instantaneous power failure/start self-holding/ reset
cannot be controlled by the network, they are invalid in the initial status.
*3 STF and STR are valid only when the internal status of the FR-A7NCA (Refer to page 112) is Operation Enable.
The motor runs at the speed of target_velocity at transition to Operation Enable.
(To change the rotation direction at transition to Operation Enable, set target_velocity to negative speed.)
