The power enabling command (corresponding to pulse enable on an electrical
drive) can be issued and/or canceled via the following paths:
S Term. 63 (central power enable)
S Term. 663 (module-specific power enable)
S Control word (from NC)
S Error (ZK1, watchdog)
5530 CYLINDER_SAFETY_CONFIG Cross reference: -
Safety configuration
Bit 0= 0: Without shut-off valve
1: With shut-off valve
Bit 1= 0: Central shut-off valve
1: Axis-specific shut-off valve
Bit 2= 0: No valve spool checkback
1: Valve spool checkback present
Bit 3= 0: Velocity controller disable with power disable (PD)
1: Velocity controller disable without power disable (PD)
Bit 4= 0: Servo solenoid valve supply disconnected with PS with
shut-off valve (irrelevant without shut-off valve)

with shut-off valve (irrelevant without shut-off valve)

The manipulated variable delay time is the time which the velocity controller
enable continues to disable after the power enable delay time (MD 5532) has
expired. This delay time is needed to allow the shut-off valve to open or, in sys-
tems without shut-off valve, to allow the valve spool to move from the fail-safe to
the zero position.
Disconnecting the shut-off valve supply
If a shut-off valve is set in MD 5530 (bit 0 or bit 1 = 1) and the supply voltage of
the servo solenoid valve is to be disconnected when the power is disabled (MD
5530 bit=0), the manipulated variable delay (MD 5531) is the time it takes until
the voltage supply of the servo solenoid valve is interrupted. The shut-off valve
can be closed during this period.
Actions on PE (ext. 24 V supply available, controllers enabled):
S 24 V supply for servo solenoid valve is switched on immediately (if it is not
already connected).
S If 24 V supply for servo solenoid valve was available, then 24 V supply for
shut-off valve is switched on immediately, otherwise it is not switched on
until power enable delay period has run down.
S After the 24 V supply for the shut-off valve has been switched on, the status
word “Velocity controller enable” is not set until the manipulated variable
enable delay has run down.
