Position Limit Parameters
Enable Min (-) and Max (+) - Select the direction in which the limit parameters are active.
Absolute Position Limits- Set the position in user units where the limits become effective, since
they are absolute a home must be completed before they will take effect.
Use percent of analog range- This option is normally used if the position mode is analog
position and the user desires to base the position limits on the percent of the analog position
min and max settings. If this box is checked the percent of analog input command will be used
instead of the absolute position limits for example in a valve application.
Limits Used Outside of Position Limits- These limits take affect when the commanded position is
outside of the Position Limit parameter values.
Velocity- This is the velocity limit in user units. If set to zero the motor / actuator will stop
near the position limit. If set to a non zero value, the velocity will be ramped to this
velocity at the position limit position.
Foldback Current- The current will be limited to this value when the commanded position
is outside of the position limit range and seating current limit has been reached and the
time has expired.
Seating Current Limit- If a hard stop is hit while outside of the position limit range the
current will built to this value for the specified time. When the time has expired Foldback
current will take effect. If it is not desired to have extra current for seating this value
should be set equal to the Foldback current.
Analog Input Calibration
The analog input for voltage and 20mA mode are calibrated at the factory, if there appears to be
error in the value being read the user may re-calibrate the input if necessary. To calibrate, first
select the mode to calibrate, Voltage Mode or 20mA Current Mode, then click the calibrate
button. The Analog Input value is displayed in the units of the selected mode. The parameter is
only available with firmware revision 2.0 or higher.
