1 SERVO PARAMETER DETAILS
1.11 Positioning extension setting servo parameters group ([Pr. PV_ _ ])
[Pr. PV07_Profile deceleration (PDEC)]
Set the deceleration used in the profile position mode (pp) and the profile velocity mode (pv).
The unit is [pulse/s
2
].
When the setting value of this servo parameter is "0", the servo motor decelerates in accordance with the time constant set in
[Pr. PT50 Speed deceleration time constant].
This function is enabled when [Pr. PT01.1] is set to "1". This function and [Pr. PT50] are mutually exclusive.
This function corresponds to [Profile deceleration (Obj. 6084h)].
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. PV09_Deceleration at forced stop (RSBDEC)]
Set the deceleration to be used for the forced stop deceleration function.
The unit is [pulse/s
2
].
When the setting value of this servo parameter is "0", the servo motor decelerates in accordance with the time constant set in
[Pr. PC24 Deceleration time constant at forced stop].
This function is enabled when [Pr. PT01.1 Speed/acceleration/deceleration unit selection] is set to "1". This function and [Pr.
PC24] are mutually exclusive.
This function corresponds to [Quick stop deceleration (Obj. 6085h)].
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. PV11_Homing speed extension setting (ZRFE)]
Set the servo motor speed for homing.
The unit is [pulse/s].
This function is enabled when [Pr. PT01.1 Speed/acceleration/deceleration unit selection] is set to "1". This function and [Pr.
PT05 Homing speed] are mutually exclusive.
The setting value will be clamped at the maximum speed. When changing the speed to the permissible speed, set the speed
in [Pr. PA28.4 Speed range limit selection].
This function corresponds to [Speed during search for zero (Obj. 6099h: 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.
