PRODUCT DESCRIPTION
Synchronous motors tolerate only extremely short interruptions of supply without loss of synchronism. In practice, the dead time should be sufficient to allow the motor no-volt device to operate. Typically, a minimum dead time of 0.2-0.3 seconds is recommended.
Description:
SDRAM (Synchronous Dynamic Random Access Memory) provides
active storage for the internal software of the ACX series controller as
well as the current copy of the database. In case of a power failure,
SDRAM is battery backed-up via an internal rechargeable NiMH
battery pack.
The ACX series controller supports 128 MB of SDRAM. The SDRAM is
partitioned for dedicated functions, as described in the table below.
For more information about Warm Start, see “Available Restart Modes
for the ACX 57xx Series Controller” on page 121
Number of Personnel Records
The ACX 57xx series controller is perfect for large systems. A controller
servicing up to 8 areas can hold 480,000 personnel records. With such a
large local storage capacity, access decisions can be made quickly
without waiting for validation by a remote server.
Validate Access Events Locally
The ACX 57xx series controller generally validate access events locally.
If it is configured for remote validation and the record is not found
locally, then a remote validation is attempted. The communication
status (offline, etc.) should not affect the controller’s ability to validate
access events locally.
