Home Switch Selection
• Parameters 825 [Dig In1 Sel] and 826 [Dig In2 Sel] are available to be set
as the Home Switch when using Encoder0, Encoder1, the Stegmann
Feedback board, or the Resolver Feedback board. Only one may be set. If
using the Multi-Device Interface board, the registration input for the
Rotary or Linear device being used is the “Home Switch” input for homing
(Refer to the
Multi-Device Interface for PowerFlex 700S Drive Installation
Instructions, publication 20D-IN004 ). Firmware version 3.003 provides
option 39 “Home Switch” in parameters 827 [Dig In3 Sel]…830 [Dig In6
Sel]. These inputs do not function as a “Home Switch” and will be
removed in a future firmware release.
• Parameter 1120 [Home Accel Time] - The homing sequence will
accelerate to the speed set in parameter 1122 [Home Speed] at this rate. It
is only used during the homing sequence.
• Parameter 1121 [Home Decel Time] - The homing sequence will
decelerate from the speed set in [Home Speed] at this rate when the
selected home type event has occurred. It is only used during the homing
sequence.
• Parameter 1122 [Home Speed] - The homing sequence will attempt to
accelerate to this speed. This speed will be maintained until the home type
event has occurred. It is only used during the homing sequence.
• Parameter 1123 [Home Position] Not supported in firmware version 3.003 -
The drive will be redefined to this position after the Homing sequence is
complete.
