Access to the hazardous area
Actuate emergency power-off switch
Due to the interruption on two channels at the emergency power-off switch, the
safety switching device is deactivated - output Q3 is immediately “0”.
Channel 1: Via the Energize input, the Compax3 devices receive the command to
guide the drive to a currentless state (using the ramp configured in the C3
ServoManager for "drive disable").
Channel 1 feedback 1: The "Controller Feedback" Compax3 outputs supply
current to Relays K1 and K2.
Channel 2: After the delay time set in the safety switching device, (this time must
be set so that all drives are stopped after it has elapsed) the output Q4 = “0”, which
in turn deactivates the Enable inputs ENAin of the Compax3 devices.
Channel 2 feedback: Via the series circuit of all feedback contacts, the “Safe
Torque-off” status (all Compax3 devices without current) is reported.
Only if the drives are all at a standstill, the safety door may be opened and the
hazardous area may be accessed.
If the safety door is opened during operation and the emergency-power-off switch
was not triggered before, the Compax3 drives will also trigger the stop ramp.
Caution! The drives may still move.
If danger to life and limb of a person entering cannot be excluded,
the machine must be protected by additional measures (e.g. a safety
door locking).
