Auto/Manual The Auto/Manual facility is essentially a higher priority reference
select. It allows a single control device to assume exclusive
control of reference select, irrespective of the reference select
digital inputs, reference select DPI commands, the reference
mask, and the reference owner.
If the “Auto/Manual” input function is closed, then the drive will
use one of the analog inputs (defined by [TB Man Ref Sel]) as
the reference, ignoring the normal reference selection
mechanisms. This mode of reference selection is called
“Terminal Block Manual Reference Selection Mode”.
If this input function is open, then the terminal block does not
request manual control of the reference. If no control device
(including the terminal block) is currently requesting manual
control of the reference, then the drive will use the normal
reference selection mechanisms. This is called “Automatic
Reference Selection” mode.
The drive arbitrates among manual reference requests from
different control devices, including the terminal block.
Acc2 & Dec2 A single input function is used to select between Accel Time 1/
Decel Time 1 and Accel Time 2/Decel Time2.
If the function is open, the drive will use Accel Time 1 as the
acceleration rate and Decel Time 1 as the deceleration rate. If
the function is closed, the drive will use Accel Time 2 as the
acceleration rate and Decel Time 2 as the deceleration rate.
Accel 2, Decel 2 One input function (called Accel 2) selects between Accel Time
1 and Accel Time 2, and another input function (called Decel 2)
selects between Decel Time 1 and Decel Time 2. The open
state of the function selects Accel Time 1 or Decel Time 1, and
the closed state selects Accel Time 2 or Decel Time 2.
MOP Inc and MOP Dec. The MOP is a reference setpoint (called the
MOP Value) that can be incremented and decremented by
external devices. These inputs are used to increment and
decrement the Motor Operated Potentiometer (MOP) value
inside the drive. The MOP value will be retained through a
power cycle.
While the MOP Increment input is closed, the MOP value will
increase at rate contained in MOP Rate. Units for rate are Hz
per second.
While the MOP Decrement input is closed, MOP value will
decrease at rate contained in MOP Rate. Units for rate are Hz
per second.
If both the MOP Increment and MOP Decrement inputs are
closed, the MOP value will stay the same.
In order for the drive to use the MOP value as the current speed
reference, either Speed Ref A Sel must be set to MOP.
