HS45
2
Each HS45 has a two-phase output (A, B) 90° out of phase, with
complements (A, B), (A Quad B Output). A marker pulse with
complement (Z, Z) is also present.
The HS45 has a diagnostic package that includes Adaptive Electronics
and a Fault-Check output and red/green LED for local indication.
With this package, the HS45 can maintain itself, and provide an
alarm if there is a problem
before
the problem causes un scheduled
downtime.
ADAPTIVE ELECTRONICS
A perfect duty cycle consists of a waveform whose “high” and
“low” conditions are of the same duration (50%/50%). It is possible
over time for the duty cycle and edge separation to change due
to component drift, temperature changes, or mechanical wear.
The Adaptive Electronics extend the life of the HS45 by constantly
monitoring and correcting duty cycle and edge separation over time.
FAULT-CHECK
If the Adaptive Electronics reach their adjustment limit, the LED will
turn red and Fault-Check alarm will notify the drive and operator of
an impending failure. This output can occur before a failure, allowing
steps to be taken to replace the unit before it causes unscheduled
downtime. Fault-Check annunciation is available as an “alarm” output
through the connector.
SAFETY
The HS45 is not considered as a safety device and is not suitable for
connection into a safety system. The mechanical overspeed switch
(option 6xx) is suitable for connection into safety systems.
CAUTION
Do not disassemble mechanical overspeed option.
Doing so may modify the overspeed set point or cause
the switch to malfunction. If the factory seals are not
intact on the overspeed switch, do not use it--return to
the factory for service and calibration.
