US - Basic Setup Parameters
Absolute Analog Speed
A uni-polar 0...+10VDC analog signal connected to terminals AN1+ and AN1-
controls the speed from 0...High Speed. The High Speed must be set in
LS02. For controllers which do not output 10V corresponding to High Speed,
the analog input can be scaled by LA05 AnIn1 Gain. In addition, the AN1+
and AN1- inputs can be programmed to receive the speed prole as either a
voltage or current signal using parameter LA50.
The speed prole acceleration, deceleration and jerk rates are externally
generated by the controller. It is possible to limit external prole rates by
setting LS15 = Internal Prole (4) and adjusting the according LS20-25 High
Speed prole rates.
The direction is determined by digital inputs assigned in LI04-11 as Up (25)
and Down (26). Both direction signals cannot be signaled simultaneously at
the beginning of a run, otherwise ‘Direction Selection Failure’ will occur.
Bi-polar Analog Speed
A bi-polar, 0... ±10V analog signal connected to the terminals AN1+ and AN1-
controls the speed from 0...±High Speed. The High Speed must be set in
LS02. For controllers which do not output 10V corresponding to High Speed,
the analog input can be scaled by LA05 AnIn1 Gain. In addition, the AN1+
and AN1- inputs can be programmed to receive the speed prole as either a
voltage or current signal using parameter LA50.
The speed prole acceleration, deceleration and jerk rates are externally
generated by the controller. It is possible to limit external prole rates by
setting LS15 = Internal Prole (4) and adjusting the according LS20-25 High
Speed prole rates.
The direction is determined by the polarity of the analog signal, although a
direction input is needed to control the start and stop routines. A digital input
must be assigned in LI04-11 as Up (25) or Down (26). Either or both Up and
Down inputs can be assigned but the direction selected does not matter since
the actual direction is determined by polarity of the analog signal. If both
directions are assigned as inputs, they cannot be signaled simultaneously at
the beginning of a run, otherwise ‘Direction Selection Failure’ will occur.
