FUNCTION Provides the ability to individually configure the
state of each relay according to the following
list. At power-up and during the reset interval
all relays are in a disabled state.
No. 0
Name NO FAULTS
Open State FAULT
Closed State NO FAULT
Notes Indicates that the Microdrive is in an operational
state. This relay is failsafe and will be energised
on a fault free power-up or fault reset. A trip
condition, power loss or Microdrive failure will
cause the relay to de-energise.
No. 1
Name START
Open State NOT STARTED
Closed State STARTED
Notes Indicates that the Microdrive has received a
START command. Relay will de-energise
when the Microdrive receives a STOP command
or if the Microdrive trips on a fault.
No. 2
Name RUN
Open State NOT RUNNING
Closed State RUNNING
Notes Indicates that the Microdrive is running.
No. 3
Name START OR RUN
Open State NOT START OR RUN
Closed State START OR RUN
Notes Microdrive is started or is running.
No. 4
Name INVERTER O/L
Open State NOT OVERLOADED
Closed State OVERLOADED
Notes Indicates that the Microdrive will eventually trip
(or has already tripped) on drive thermal trip
if left running at the present current. The
overload will go inactive if the output current
is reduced to the Microdrive rating or less. This
is a predictive overload and the relay will pulse
to warn of impending trip.
No. 5
Name MOTOR O/L
Open State NOT OVERLOADED
Closed State OVERLOADED
Notes Indicates that the motor will eventually trip (or
has already tripped) on motor thermal trip if
left running at the present current and speed.
The overload will go inactive if the cooling is
improved sufficiently (higher speed) or the
current is reduced sufficiently. This is a
predictive overload and the relay will pulse to
warn of impending trip.
No. 6
Name FREQ SENSE
Open State BELOW Fr OFF
Closed State ABOVE Fr ON
Notes See Screens 2930. Becomes active when
the inverter frequency has exceeded the upper
frequency sense point (FR ON - Screen 29).
Becomes inactive when the frequency goes
below the lower frequency sense point (FR
OFF - Screen 30). If the lower frequency
sense point is set to zero, this signal will
become inactive only when the Microdrive
stops (comes out of run). If the upper
frequency sense point is 0 then it will become
active as soon as the Microdrive goes into run.
The upper frequency sense point will always
be higher than the lower frequency sense
point.
No. 7
Name CURRENT SENSE
Open State BELOW SENSE I
Closed State ABOVE SENSE I
Notes See Screen 31. Indicates that the current has
exceeded the current sense point (Screen
31). This relay output exhibits 5% hysteresis.
No. 8
Name INVERTER DIRECTION
Open State FORWARD
Closed State REVERSE
Notes The relay reflects the sign of the output
frequency.
No. 9
Name COMMS OUTPUT
Open State NOT SET
Closed State SET
Notes This signal can be toggled by the serial
communications line and has no relation to the
state of the Microdrive. It is intended purely for
user convenience.
No. 10
Name AT SET FREQ
Open State NOT AT FREQUENCY
Closed State AT FREQUENCY
Notes ±0.5Hz. This signal indicates that the Microdrive
is not accelerating or decelerating.
No. 11
Name OVERLOAD ALARM
Open State NOT OVERLOADED
Closed State OVERLOADED
Notes Motor overloaded or inverter overloaded.
No. 12
Name POWER FLOW
Open State Inverter supplying power.
Closed State Inverter regenerating.
No. 13
Name FEEDBACK SENSE
Open State FEEDBACK ABOVE REFERENCE
Closed State FEEDBACK BELOW REFERENCE
Notes See Screen 54. Indicates that the feedback
signal has exceeded the reference signal plus
half the hysteresis (Screen 54).
SETTING UP If relay outputs are not required no adjustment
is required. These screens may be left in any
state.
Select the desired relay output mode for each
required relay.
