Set

Home Sensor
Backoff

USINT

1

Causes the drive to move in the direction opposite
the direction specified by the Homing Velocity
setting, when the homing procedure is started with
the Sensor input active. Motion will continue in the
reverse direction (moving at the Homing Accel,
Homing Decel, and Homing Velocity settings), until
the Sensor input is detected inactive, at which point
the normal homing procedure will take over.
Controls whether the drive backs off the sensor if
the sensor is active at the start of the homing
operation.

Note: This parameter does not apply if 'Home to
Marker' is selected as the Homing Type.
0 - Disable (default)
1 - Enable

339

Set

Homing Velocity

DINT

4

Cnts /
Sec

The commanded velocity used during homing. The
sign of the parameter value specifies the direction of
motion during homing.
Range: -0x7fffffff to 0x7fffffff
Default: 100000

340

Set

Homing Accel/
Decel

UDINT

4

Cnts /
Sec

2

The acceleration and deceleration rate used during
homing.
Range: 0 to 0x7fffffff
Default: 100000

341

Set

Home Offset
Move

DINT

4

Cnts

The distance the motor position will be from the
home position after the homing procedure is
complete.
Range: -0x7fffffff to 0x7fffffff
Default: 0

342

Set

Homing Stop
Decel

UDINT

4

Cnts /
Sec

2

The deceleration rate used to bring the motor to a
stop when a homing procedure is terminated with
the Stop Homing input or the Stop Homing
command.
Range: 0 to 0x7fffffff
Default: 100000

343

Set

Home Sensor
Polarity

USINT

1

Specifies the digital input state that the drive uses
to determine if the Home Sensor input is active.
0 - Inactive to active transition (default)
1 - Active to inactive transition

344

Set

Home Position

DINT

4

Cnts

This value is used as the home position when the
Define Home input is activated, or at the completion
of a homing procedure.
Range: -0x7fffffff to 0x7fffffff
Default: 0

345

Set

Homing Creep
Velocity

UDINT

4

Cnts /
Sec

For the Homing Type selection 3 - Home to Sensor,
Backward to Marker -
this velocity is used to travel
back to the marker after the drive finds the sensor
edge.
Range: 0 to 0x7fffffff
Default: 10000
