holding zero velocity; drive then transfers velocity reference back to its previous
source once it receives a start command.
If P35[Motor Ctrl Mode] = 0 “Induction VHz” or 1 “Induction SV”
The drive then ramps to zero at the rate set in P736 [Find Home Ramp].
If the drive travels passed the proximity switch during decel
The drive reverses direction at a speed of 1/10 of P735 [Find Home Speed]. The
drive must then receive a rising edge of the proximity switch followed by a falling
edge pulse. Upon receiving the falling edge pulse the drive will decel at the rate set
in P736 [Find Home Ramp]. When the motor is “At Zero Speed,” the homing
sequence completes.
If the drive remains on proximity switch during decel
The drive reverses direction at a speed of 1/10 of P735 [Find Home Speed].
When the falling edge of the limit/proximity switch is reached the drive will
decel at rate set in P736 [Find Home Ramp]. When the motor is “At Zero
Speed,” the homing sequence completes.
NOT Hold At Home, P731 Bit 7
If a position control type mode is selected in P313 [Actv SpTqPs Mode] the drive
continues running, holding position and transferring position reference back to
its previous source. If velocity control type mode is selected in P313 [Actv SpTqPs
Mode] the drive continues running holding zero velocity and transferring
velocity reference back to its previous source.
Hold At Home, P731 Bit 7
If a position control type mode is selected in P313 [Actv SpTqPs Mode] the drive
continues running, holding position; the drive then transfers position reference
back to its previous source once it receives a start command. If velocity control
type mode is selected in P313 [Actv SpTqPs Mode] the drive continues running
