3–6 Installation/Wiring for Stand-Alone Drives
Speed Select/Frequency Reference
The drive speed command can be obtained from a number of different
sources. The source is determined by drive programming and the
condition of the Speed Select Inputs on TB6 (or reference select bits
of command word if PLC controlled - see Appendix A).
The default source for a command reference (all speed select inputs
open) is the selection programmed in [Freq Select 1]. If any of the
speed select inputs are closed, the drive will use other parameters as
the speed command source. See Table 3.B and the examples that
follow.
Table 3.B
Speed Select Input State vs. Frequency Source
Important: The final speed command may be affected by the type of
modulation selected with [Speed Control], parameter 77.
See [Speed Control] in Chapter 7 for further information.
Important: If a bi-polar input option (LA6 or LA7) is installed, the
signal is designated “Analog Input 0.” Note the following:
3 Wire Control – If [Input Mode] is set to “3 Wire”
and the bi-polar input is selected as the active
frequency reference [Freq Select 1 or 2], it is
assumed that direction control is desired via analog
polarity. If another source has control of direction, a
“Bipolar Direction” fault (F16) will occur. If
direction control via polarity is not required, bit 7 of
[Direction Mask] should be set to “0.” This causes
the input to be treated as a 0-10V frequency
reference only. Negative analog signals are treated
as zero and direction control must come from
another source.
2 Wire Control – If [Input Mode] is set to “2 Wire,”
it is assumed that direction control is provided via
the 2 wire inputs (Run Forward and Run Reverse).
Bit 7 of [Direction Mask] must be set to “0.” This
causes the input to be treated as a 0-10V frequency
reference only. Negative analog signals are treated
as zero. Failure to set the Mask will generate a
“Bipolar Direction” (F16) fault.
