1 SERVO PARAMETER DETAILS
1.9 Positioning control setting servo parameters group ([Pr. PT_ _ ])
[Pr. PT19_Position range output 1 a (*LPP1)]
Set the address increasing side of the position range output 1 address.
Use this servo parameter and [Pr. PT21 Position range output 1 address -] to set the range where position range 1 (POT1)
turns on.
This function is enabled in the profile position mode and positioning mode (point table method).
The unit can be changed to 0.001 mm, 0.0001 inch, 0.001 degree or pulses with [Pr. PT01.2 Unit for position data].
If [Pr. PT19] is set to a value less than [Pr. PT21] while [Pr. PT01.2] is set to "3" (pulse), [AL. 037 Parameter error] occurs.
When [Pr. PT01.2] is set to "2" (degree), set [Pr. PT21] as the starting point and [Pr. PT19] as the ending point.
An example setting of the degree unit is as follows.
The output range is the section where the servo motor moves from "-" to "+" in the CCW direction.
Set the output range of moving range A as follows:
• [Pr. PT21] = 315.000 degrees
• [Pr. PT19] = 90.000 degrees
Set the output range of moving range B as follows:
• [Pr. PT21] = 90.000 degrees
• [Pr. PT19] = 315.000 degrees
The setting range is 0 to 359.999 degrees. If a value out of the setting range is set, the value will be converted as shown in the
table below.
The values of the output range shown above will be the values after conversion.
[Pr. PT21_Position range output 1 address - (*LNP1)]
Set the address decreasing side of the position range output 1 address.
The other specifications are the same as [Pr. PT19 Position range output 1 a].
