Description:
High-speed, optically-isolated filtered
registration input for each axis. Inputs can
be either 5 or 24V DC. Refer to Figure 4.5 for
typical registration device inputs.
Note: To further reduce electrical noise, a
dedicated power supply may be required for
the registration sensors.
You can disable the registration input filters
by removing jumpers P0-P3 on the input
wiring board.
Two software-programmable outputs are
available:
• A voltage corresponding to the motor
velocity and direction of rotation will be
present between these terminals. ±1.0V/
krpm is available. Minimum impedance that
can be placed across this output is 10k ohm.
• A voltage corresponding to positive and
negative current will be present between
these terminals. ±2.5V DC equals 100% of
motor continuous current rating. ±5.0V DC
equals 200%. Minimum impedance that can
be placed across this output is 10k ohms.
Any axis analog current/voltage output may
be linked to either analog output using
internal software parameters. By default
Axis 0 velocity is linked to A TEST 0 and
Axis 0 current is linked to A TEST 1.
When you apply 24V AC/DC control power
to the system and no system faults are
detected, the Drive OK relay contact closes.
The contact remains closed until a drive fault
occurs, the DC bus voltage is lost, or you
remove 360/480V input power from the
system module. If a drive fault is detected or
the DC bus voltage is lost, the relay contact
opens. You can wire the Drive OK contacts
into the Estop string to open the main power
contactor if a fault occurs. The contact rating
is 115V AC or 24V DC, 1A.
