⇒
Run Freq Hyst
This parameter provides a plus-or-minus value for the Run Frequency setting.
Parameter Type — Numerical
Factory Default — 0.0
Changeable During Run — Yes
Minimum — 0.0
Maximum — 30.0
Units — Hz
Run Time Alarm Setting
Program
⇒
Protection
⇒
Run Time Alm Set
This parameter sets a run-time value that, once exceeded, provides an output
signal. The output signal may be used to control external equipment or used to
engage a brake.
Note: The time displayed is 1/10th of the actual time
(0.1 hr. = 1.0 hr.).
Parameter Type — Numerical
Factory Default — 175.0
Changeable During Run — Yes
Minimum — 0.1
Maximum — 999.9
Units — Hours (X 100)
RX Speed Frequency #1
Program
⇒
Freq Settings
⇒
RX Speed Freq #1
This parameter is used to set the direction, gain, and bias of the RX input
terminal when the RX terminal is used as the control input while operating in
the Speed Control mode.
RX Input Speed/Direction Control Setup
Perform the following setup to allow the system to receive Speed control input
at the RX input terminal:
• Program
⇒
Utility Group
⇒
Frequency Mode
⇒
Rx.
• Program
⇒
Utility Group
⇒
Command Mode
⇒
Terminal Block.
• Provide a Run command (F and/or R).
Speed/Direction Control
Perform the following setup to allow the system to perform Speed control from
the RX input terminal:
• Set RX Speed Frequency #1,
• Set the RX input signal level (RX Speed Ref #1) that represents RX Speed
Frequency #1,
• Set
, and
• Set the RX input signal level (RX Speed Ref #2) that represents
.
Once set, as the RX input voltage changes, the directional information, and the
output frequency of the ASD will vary in accordance with the above settings.
This parameter sets RX Speed Frequency #1 and is the frequency that is
associated with the setting of
Speed Control mode.
