[Pr. PT15_Software position limit + (LMP)]
Set the address increasing side of the software position limit.
Set the stop method in [Pr. PD12.2 Stop process selection at software position limit detection].
When [Pr. PT15] and [Pr. PT17 Software position limit -] are set to the same value, the software position limit is disabled.
• When using pulses as the unit
When the value set in [Pr. PT15] is smaller than the value set in [Pr. PT17], the software position limit is disabled.
This function is enabled in the cyclic synchronous position mode and the profile position mode. The setting is disabled during
homing.
Change this function during servo-off, in the homing mode, velocity mode, or torque mode.
When the setting is changed during servo-on in the position mode, [AL. 035 Command frequency error], [AL. 069 Command
error], and [AL. 098 Software position limit warning] may occur, depending on the setting order of [Pr. PT15] and [Pr. PT17].
This function corresponds to [Max position limit (Obj. 607Dh: 2h)].
When the object is mapped to the cyclic communication, do not write values with engineering tools because the controller
overwrites the servo parameter values written with engineering tools.
[Pr. PT17_Software position limit - (LMN)]
Set the address decreasing side of the software position limit.
The other specifications are the same as [Pr. PT15].
[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.
If the value set in [Pr. PT19] is less than the value set in [Pr. PT21], [AL. 037 Parameter error] occurs.
This function is enabled in the profile position mode.
[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].
[Pr. PT29_Function selection T-3 (*TOP3)]
[Pr. PT29.0_Device input polarity 1]
Select the proximity dog input polarity.
0: Dog detection with off
1: Dog detection with on
