8.3
Device Control
The device control for the servo drive is carried out in the order shown in the following flowchart. Control-
word (Object 6040h) controls the operating status of the servo drive, and Statusword (Object 6041h) is used to
monitor this status.
∗
1.
In Quick stop Active state, the SERVOPACK automatically transits to the Switch on Disabled state at the following
cases:
-The main power supply was turned off.
-HWBB signal was inputted.
-The motor was stopped.
∗
2.
In Switched on state, the SERVOPACK automatically transits to the Switch on Disabled state at the following cases:
-The main power supply was turned off.
-HWBB signal was inputted.
-Motor operation was already enabled by the engineering tool (SigmaWin for
Σ
-V-SD (MT)).
∗
3.
In Ready to Switch on state, the SERVOPACK transits to the next state in the following cases:
-The main power supply was turned on.
-EtherCAT State Machine (ESM) is in Operational state.
-The servomotor is not run by SigmaWin for
Σ
-V-SD (MT).
∗
4.
In Operation Enabled state, the SERVOPACK automatically transits to the Switch on Disabled state at the following
cases:
-The main power supply was turned off.
-HWBB signal was inputted.
Note 1.
shows state.
2. STW means the Statusword of Object 6041h.
3. ______ (underline) means the control command of Controlword (Object 6040h).
