DI HOA Start
This digital input function provides Hand-Off-Auto control. It functions like a
three-wire start signal; with the exception, that it does not require the DI Stop to
be high for a full input cycle before the drive looks for a rising edge on DI HOA
Start. Use this feature by configuring P176 [DI HOA Start].
DI MOP Inc, DI MOP Dec
These digital input functions are used to increment and decrement the Motor
Operated Potentiometer (MOP) value inside the drive. The MOP is a reference
value that can be incremented and decremented by external devices. The MOP
value has a configurable preload that is retained through a power cycle. For the
drive to use the MOP value as the current speed reference, either P545 [Speed
Ref A Sel], P550 [Speed Ref B Sel], or P563 [DI ManRef Sel] must be set to
P558 [MOP Reference].
DI Accel 2, DI Decel 2
These digital input functions toggle between primary and secondary ramp rates.
For example, with a digital input programmed to P179 [DI Accel 2], an open
digital input follows P535 [Accel Time 1]. A closed digital input follows P536
[Accel Time 2].
DI SpTqPs Sel 0 and 1
These digital input functions provide the ability to switch between different
Speed/Torque/Position modes, (P309 [SpdTrqPsn Mode A], P310 [SpdTrqPsn
Mode B], P311 [SpdTrqPsn Mode C], and P312 [SpdTrqPsn Mode D]) from
digital input combinations. See
Speed Torque Position on page 266 for a
complete description of these modes and the digital input combinations that
activate each mode.
DI Stop Mode B
This digital input function selects between two different drive Stop modes. If the
input is open, then P370 [Stop Mode A] selects which Stop mode to use. If the
input is closed, then P371 [Stop Mode B] selects which Stop mode to use. If this
input function is not configured, then P370 [Stop Mode A] always selects which
Stop mode to use. See also
Stop Modes on page 96 for more details.
