5.3.5 Positioning
This section describes the parameter details about positioning.
Parameter Details
Positioning Completion Range
(Object: 0x64, Attribute: #90; Pn850)
Use the Positioning Completion Range to set the positioning completed range, i.e., to deter-
mine if the axis is In-position. The setting unit is [steps]. When the Positioning Completion
Range is set to 0, an In-position check will not be performed.
Fig. 5.9 Positioning Completion Range
When the following condition is satisfied in the above figure, the axis is viewed as being at
the In-position and the In-position Flag in the response data will be set to 1.
• X = (End point - Present value)

Pn850
Positioning Monitor Time
(Object: 0x64, Attribute: #91; Pn851)
Use the Positioning Monitor Time to set the time for performing In-position check. The set-
ting unit is [ms]. If, after the move command distribution from the DeviceNet Unit has been
completed, the positioning completed range is not entered within the time set, A.9A (posi-
tioning a completion timeout warning) will be sent.
If this parameter is set to 0, the positioning time is not monitored.
Positioning Near Range
(Object: 0x64, Attribute: #92; Pn852)
Use the Positioning Near Range to set the range for positioning area proximity to be
detected. If the difference between the present position and the target position are within this
parameter range, the proximity signal in the response data will be set to 1. The setting unit is
[steps].
