N2 Points
Point Description
3-05: Keypad Setpoint Command
This point monitors and controls the Keypad Setpoint Command. The units for this point
are defined by Drive Parameter #31 (Units). The minimum and maximum values for this
point are defined by Drive Parameter #75 (Feedback @ Min) and #76 (Feedback @ Max),
respectively. The range of adjustment for Drive Parameters #75 and 76 is –32768 to
32767.
The ability to command this point through the N2 network is dictated by Drive Parameter
#30 (Control) and the drive HOA (Refer to Point 3-03). If this point is not being overridden,
this value can also be set using the drive’s MOP function or the UP and DOWN arrow keys
on the drive keypad.
NOTE: If the MOP function or the drive keypad is currently changing the keypad setpoint
command, serial override commands of this point will not be accepted.
