PT57
ZSTH
Home
position shift
distance
(extension
parameter)
This parameter is the extension parameter of [Pr. PT07].
When [Pr. PT57] is used, the home position shift distance is calculated as follows.
Home position shift distance = [Pr. PT07] + ([Pr. PT57] × 65536)
This function will be enabled in the profile mode.
The unit can be changed to 10
-3
[degree] or [pulse] with the setting of [Pr. PT01].
Setting range: 0 to 32767

PT59
DCTH
Travel
distance after
proximity dog
(extension
parameter)
This parameter is the extension parameter of [Pr. PT09].
When [Pr. PT59] is used, the travel distance after proximity dog is calculated as follows.
Travel distance after proximity dog = [Pr. PT09] + ([Pr. PT59] × 65536)
This function will be enabled in the profile mode.
The unit can be changed to 10
-3
[degree] or [pulse] with the setting of [Pr. PT01].

_ _ _ x Home position return - Deceleration time constant selection
Select a parameter used for setting the deceleration time constant at home position return.
The acceleration time constant is fixed to [Pr. PT61].

time constant
Set the acceleration time constant for the home position return. Set an acceleration time taken from
0 r/min to the rated speed.
This function will be enabled in the profile mode.
When "Using [Pr. PT61] as deceleration time constant (_ _ _ 0)" is selected in "Home position
return - Deceleration time constant selection" of [Pr. PT60], the value set in this parameter is used
as a deceleration time constant at home position return.
This parameter corresponds to "Homing acceleration (Index: 609Ah)". When this parameter is
mapped to the link device of CC-Link IE Field Network Basic, the value written with MR
Configurator2 is overwritten by the controller. Thus, do not write a value with MR Configurator2.

time constant
Set the deceleration time constant at the home position return. Set a deceleration time taken from
the rated speed to 0 r/min.
This function will be enabled in the profile mode.
When "Using [Pr. PT62] as deceleration time constant (_ _ _ 1)" is selected in "Home position
return - Deceleration time constant selection" of [Pr. PT60], the value set in this parameter is
enabled.
Setting range: 0 to 20000

PT63
ZSP2L
Zero speed 2
level
Set a speed level for turning on the zero speed 2.
When the state in which the absolute value of the servo motor speed exceeds the parameter
setting value continues for the time set in [Pr. PT64 Zero speed 2 filtering time] or longer,
"Statusword (Index: 6041h) bit 12 Speed" will be turned off.
This function will be enabled in the profile velocity mode.
This parameter corresponds to "Velocity threshold (Index: 606Fh)". When this parameter is
mapped to the link device of CC-Link IE Field Network Basic, the value written with MR
Configurator2 is overwritten by the controller. Thus, do not write a value with MR Configurator2.
