NOTE:
THE FOLDBACK SELECTION MAY NOT BE AVAILABLE ON SOME EARLY
VERSIONS OF SOFTWARE.
External Trip
- This parameter programs the control to expect to see a Normally Closed (NC)
switch at the external trip input terminal at the main control board's terminal strip. The choice is to
turn it ON or turn it OFF. If turned ON, the control will shut down if the circuit tied into the External
Trip Input opens. This is useful for connecting a motor overload thermostat.
Following Error
- Following error is the programmable tolerance for the At Speed opto-isolated
output. This parameter determines if the control will monitor the amount of following error that
occurs in an application or it will ignore it. This parameter can be set to ON or OFF. The factory
setting is OFF.
Miscellaneous Block
Restart Auto/Man
- Used to set the restart feature of the control to be AUTOMATIC or MANUAL
when a fault or a power failure occurs. MANUAL should be chosen to disable the auto restart
function. The factory preset is MANUAL.
Restart Fault/Hr
- Sets the maximum number of automatic restart attempts that will be allowed
before the control will require a manual restart. This feature is useful in applications that require
unattended operation and automatic operation even in the event of various fault conditions such as
unscheduled power outages. After one hour without reaching the programmed maximum # of
faults, the number of allowable restarts will be reset to the value specified in the # of Restarts
parameter. The range of adjustment is 0-10 restart faults/hr. The factory preset is 0.
Restart Delay
- Sets the amount of time in seconds between a fault and an attempted automatic
restart. This feature is useful in setting a sufficient time period for a fault to be cleared before an auto
restart is attempted. The range of adjustment is 0-120 seconds. The factory preset is 0 seconds.
Factory Settings
- This parameter can be activated by selecting YES which is done by pressing
the Up arrow key followed by an ENTER keystroke. This function is used to reset all parameters to
the factory preset values should drive operation become unstable, erratic or unpredictable. The
display will say "operation done" when the values have been reset. This parameter is not preset or
permanently programmable. It must be accessed each time a return to factory settings is desired.
Homing Speed
- In the BIPOLAR and SERIAL Operating Modes, this control features an ability to
rotate (ORIENT) the motor shaft to a "home" position when the Orient input switch on the controls
main terminal strip is activated. This parameter sets the speed at which the motor will rotate in the
Forward direction when the Orient input switch is closed. The speed can be faster or slower than
your "normal" operating speed. The range of adjustment is 0-MAX SPEED. The factory preset is
100 RPM.
