PDS State Control Method
This section describes the relationship between the setting values of the PDS State Control Method
axis parameter and the PDS states.
When PDS State Control Method Is Set to 0
The following operation is performed when PDS State Control Method is set to 0: Switched on by
Servo OFF.
• After communications with the Servo Drive is established, MC Function Module automatically
changes the PDS state to Servo Ready (Switched on).
• If Enable of the MC_Power (Power Servo) instruction changes to TRUE in the Servo Ready
(Switched on) state, the PDS state changes to Servo ON (Operation enabled). This operation cor-
responds to 4: Enable operation in the state transition diagram.
• If Enable of the MC_Power (Power Servo) instruction changes to FALSE in the Servo ON (Opera-
tion enabled) state, the PDS state changes to Servo Ready (Switched on). This operation corre-
sponds to 5: Disable operation in the state transition diagram.
When PDS State Control Method Is Set to 1
The following operation is performed when PDS State Control Method is set to 1: Ready to
switched on by Servo OFF.
• After communications with the Servo Drive is established, MC Function Module automatically
changes the PDS state to Main Power OFF (Ready to switch on).
• If Enable of the MC_Power (Power Servo) instruction changes to TRUE in the Main Power OFF
(Ready to switch on) state, the PDS state changes to Servo ON (Operation enabled). This opera-
tion corresponds to 3: Switch on and 4: Enable operation in the state transition diagram. The
steps 3 and 4 are performed simultaneously.
• If Enable of the MC_Power (Power Servo) instruction changes to FALSE in the Servo ON (Opera-
tion enabled) state, the PDS state changes to Main Power OFF (Ready to switch on). This opera-
tion corresponds to 5: Disable operation and 6: Shutdown in the state transition diagram. The
steps 5 and 6 are performed simultaneously.
Additional Information
PDS State Control Method is set to 0 by default.
