1.9 Positioning control setting servo parameters group ([Pr. PT_ _])
[Pr. PT08_Homing position data (ZPS)]
Set the address that is to be the reference point of the machine coordinate system.
Subtracting the setting value of this servo parameter from the machine home position gives the coordinate of the home
position. The value in [Position actual value (Obj. 6064h)] changes at the same time as the homing completion.
The setting value of this servo parameter is reflected at completion of homing or when the servo amplifier is connected to a
network.
This function is enabled in the cyclic synchronous position mode and the profile position mode.
This function corresponds to [Home offset (Obj. 607Ch)]. The relation between [Home offset] and this servo parameter is as
follows.
[Home offset] = - [Pr. PT08]
The value that is set in this servo parameter is not reflected when the homing is incomplete.
Setting this servo parameter will compensate the software position limit.
After compensation, [Max position range limit (607Dh: 02h)] = [Max position range limit] - [Home offset]
After compensation, [Min position range limit (607Dh: 01h)] = [Min position range limit] - [Home offset]
[Pr. PT09_Travel distance after proximity dog (DCT)]
Set a travel distance after proximity dog at homing for the count type (Front end detection Z-phase reference) (Homing
method -2, -34) and dog reference.
The following shows the homing of the dog reference.
• Dog type rear end reference homing (Homing method -6, -38)
• Count type homing (Front end reference) (Homing method -7, -39)
• Dog type front end reference homing (Homing method -10, -42)
• Homing without index pulse (Homing method 19, 20, 21, 22, 23, 24, 27, 28)
This function is enabled in the cyclic synchronous position mode and the profile position mode.
[Pr. PT10_Stopper type homing - Stopping time (ZTM)]
Set a time from a moving part touches the stopper and torques reach to the torque limit of [Pr. PT11 Stopper type homing -
Torque limit value] to a home position is set for the stopper type homing.
This function is enabled in the cyclic synchronous position mode and the profile position mode.
[Pr. PT11_Stopper type homing - Torque limit value (ZTT)]
Set a torque limit value with [%] unit to the maximum torque at stopper type homing.
This function is enabled in the cyclic synchronous position mode and the profile position mode.
[Pr. PT12_Rough match output range (CRP)]
Set the range of the command remaining distance to output the rough match.
This function is enabled in the profile position mode.
