Compax3 device description
192-120102 N7 - February 2004
41
Basic functions:
Compax3 devices disabled by:
Channel 1: Energize – input to “0” through open contacts of Emergency Power-off
Module (13-14)
Channel 2: Enable input to "0" through open contacts of Emergency power-off
module (57 -58)
Activate Emergency power-off module
Before the Compax3 can be placed in operation, the Emergency power-off module
must be activated by a pulse to Input S33/S34.
Prerequisite:
!
S3 closed
!
Safety door closed: This is required before the safety door monitor enables the
Emergency power-off module via Input S11 (by closing the contacts between 23
and 24).
!
Current to K2, K3 and K4
!
K2: receives current if all Compax3's are currentless (contact closed in
currentless state) = Channel 2 feedback
!
K3: receives current if Compax3 Device 1 is currentless (output = „1“ in
currentless state) = Channel 1 feedback
!
K4: receives current if Compax3 Device 2 is currentless (output = „1“ in
currentless state) = Channel 1 feedback
If S33 and S34 of the Emergency power-off module are briefly connected (pulse)
the contacts will be closed (between 13 and 14 and between 57 and 58)
Supplying current to Compax3
!
Compax3 devices are enabled by the Energize input and the Enable input via the
Emergency power-off module. (If a fault is still pending on Compax3, it must
previously be reset. The acknowledge/reset function depends on the type of the
Compax3 device).
!
Power is supplied to K1 and the mains power voltage is switched on by a K2
contact or by the closed safety door.
!
The motors are energized with current.
Summary: Compax3 is not energized with current unless the feedback functions
via K2, K3 and K4 are capable of functioning.
Case 1: Normal access to the hazardous area
Activate Emergency power-off switch
Disconnecting the connection between S11 and S31 /S32 (2 channels) deactivates
the Emergency power-off module and causes Contacts 13 - 14 to open
immediately.
Channel 1
: Compax3 devices receive the command via the Energize input to guide
the drive to a currentless state (using the ramp configured in the C3 ServoManager
for "drive disable").
Channel 1 feedback:
The "Controller Feedback" Compax3 outputs supply current
to Relays K3 and K4.
Channel 2:
After the delay time set in the Emergency power-off module, (this time
must be set so that all drives are stopped after it has elapsed) the contacts
