SV160E2
Definition of Home Position
The Home Position is any position on your machine that you can sense and stop at. Once at the Home Posi-
tion, the Profile Position must be set to an appropriate value. If you use the unit’s
CW/CCW Find Home
com-
mands, the Profile Position will automatically be set to zero once the home position is reached.
When the
Profile Position is preset or homed, the Encoder Position will also be set to the same value.
Defining a Home Position is completely optional. Some applications, such as those that use an
SV160E2 for speed control, don’t require position data at all.
Definition of Homing Speed
Homing speed is the speed of the final segment of the homing move. It is equal to 10% of the Target Speed
that is programmed as part of the move.
Position Preset
One of the ways to define the Home Position is to issue the Preset Position command over the network. The
Profile Position can be preset anywhere in the range of -1,073,741,824 to +1,073,741,823.
CW/CCW Find Home Commands
The other choice is to use the unit’s Find Home commands to order the SV160E2 to find the Home Position
based on sensors brought into the unit. The CW Find Home command begins searching by rotating the motor
shaft in the clockwise direction and ends when the home sensor triggers while the SV160E2 is rotating in the
clockwise direction
at the Homing Speed.
The CCW Find Home command operates in the same way but
starts and ends with motion in the counter-clockwise direction.
Homing Inputs
Up to three physical DC inputs can be used when homing the driver.
Home Input:
This input is used to define the actual home position of the machine.
CW Limit Switch Input:
This input is used to prevent overtravel in the clockwise direction.
CCW Limit Switch Input:
This input is used to prevent overtravel in the counter-clockwise direction.
Homing Configurations
A SV160E2 must have one of its DC inputs configured as the home input before one of the
CW/CCW Find
Home
commands can be issued.
You do not have to configure and use CW or CCW Limits. If you choose to configure the
module this way, then the SV160E2 has no way to automatically prevent over travel during a
homing operation. In linear applications, you must prevent over travel by some external
means, or ensure that the homing command is issued in the direction that will result in reach-
ing the homing input directly.
This chapter explains the various ways of homing an SV160E2. Inputs used to
home the unit are introduced and diagrams that show how the unit responds to a
homing command are given.
