Homing Profiles (continued)
Profile with Overtravel Limit
Figure R4.2 below shows the move profile generated by a CW Find Home command when you use the CW
Overtravel Limit.
The profile is generated when you encounter an overtravel limit in the direction of travel. (In this example,
hitting the CW limit while traveling in the CW direction.)
The SV160E2 will stop and issue an Input Error to your host if you activate the overtravel
limit associated with travel in the opposite direction. i.e. Activating the CCW limit during a
CW Find Home command. This can occur if the overtravel limits are not wired to the
SV160E2 correctly, or if both overtravel limits are activated while the unit is trying to find the
home position.
Figure R4.2 Profile with Overtravel Limit
1) Acceleration to the Programmed Speed
2) Run at the Programmed Speed
3) Hit CW Limit and stop, followed by a two second delay. The Immediate Stop Deceleration value is
used to decelerate at this point. If this parameter equals zero, the motor stops without deceleration.
4) Acceleration to the Programmed Speed opposite to the requested direction.
5) Run opposite the requested direction until the Home Input transitions from Active to Inactive
6) Deceleration and stop, followed by a two second delay.
7) Return to the Home Input at the Homing Speed. (10% of the Programmed Speed.) Stop when the
Home Input transitions from Inactive to Active.
If the overtravel limit is active when the Find Home Command is issued, the profile will begin
at step 4.
