SIMOVERT MASTERDRIVES
A positive edge on the "enable homing" control signal enables the
homing logic for one cycle. When the home position is detected, the
position is set to the set value and the "home position detected"
checkback signal is output [330.7 and 335.7]. The checkback signal
remains active until the "enable homing" control signal is canceled
again. The time chart below illustrates the sequence.
