è
Establish CVE control interface
Establish the CVE interface as a control interface via the FCT by selecting “Control via Ethernet CVE”
on the control interface page, then “saving”, and switching the controller off and back on again.
–
As soon as the controller is ready, bit 2 is set to the value 1 (MC = 1) in the SPOS status byte
(CVE object 239/0).
Takeover of master control through CVE
After the FCT device control is deactivated, the CVE control interface does not automatically receive
back master control but must actively take it back itself.
1. Establish an Ethernet connection with the controller.
2. Write the value 2 to the CVE object 3/0.
–
The CVE interface has the master control.
Enable operation
Requirements:
–
The drive is switched on, the CVE interface has been set and there is no malfunction.
–
The inputs of the emergency stop interface [X4] are active, that is, 24 V must be applied to TO and
ES and 0 V to RB (
è
4.2.5 Emergency stop interface [X4]).
–
In the control byte CPOS (CVE object 240/0), bit 1 and 2 must be set to the value 0
(START = 0 and HOM = 0).
1. Enable the drive (controller) by setting bit 0 in the control byte CCON (CVE object 240/0) to the
value 1 (ENABLE = 1).
–
As soon as this status has been reached, bit 0 in the SCON status byte (CVE object 239/0) is set
to value 1 (ENABLED = 1).
2. Enable the operation by setting bit 1 in the control byte CCON (CVE object 240/0) to the value 1
(STOP = 1).
–
As soon as this status has been reached, bit 1 in the SCON status byte (CVE object 239/0) is set
to value 1 (OPEN = 1).
The operation is enabled (controlled status).
